Foreground and background in the narrative discourse of Luke’s Gospel: Some remarks on the function of the Greek imperfect and pluperfect indicative tense-forms1

The distinction between foreground and background in narrative discourse is a pervasive phenomenon in the literatures of the world, and languages have a variety of devices to indicate this distinction. The use of the tense-forms of the verb for this purpose has been studied in a variety of languages, including the Greek of the New Testament. The aim of this study is to explore, describe, and classify the functions of the imperfect and pluperfect indicative in the Gospel of Luke’s narrative discourse. The study is restricted to narrative proper (which includes embedded narratives, such as the parables of Jesus), but excludes direct and indirect discourse, and comments by the author of the Gospel. The findings are that the main function of the imperfect in the Gospel of Luke’s narrative discourse is to provide background information. This is related to the imperfect’s “imperfective” aspect and its characteristic linking to another verbal utterance, which also promotes cohesion in the text. The imperfect’s main specific use is to provide background information in the form of setting the scene for events that follow in the main storyline. It is also used in the introduction of participants in a scene, to provide supplementary details, in epilogues, and in explanatory clauses. In a few instances, the imperfect expresses foreground information. The pluperfect is always used for background information. This is related to its characteristic of describing a continuing state in the past which is the result of an event in the past. The pluperfect’s specific uses are to set the scene for mainline events that follow, together with the imperfect; to provide supplementary details about persons, events, etc. in the main storyline; and to explain the reason for events in the main storyline.


The aim and scope of the paper
The aim of the research that underlies this paper is to investigate, describe, and classify the functions of the imperfect and pluperfect indicative tense-forms (henceforth, "imperfect" and "pluperfect", respectively) in indicating foreground and background information in the narrative discourse of the Gospel of Luke (henceforth, "Luke"). The study is confined to narrative proper in Luke, i.e. the main storyline and offline information in narrative discourse. The study also includes embedded narratives, such as the parables of Jesus, but excludes direct and indirect discourse, and comments by the author.
This paper is the first attempt at a detailed analysis of the function of the imperfect to denote foreground and background in Luke as a whole. Although the backgrounding function of the imperfect in the New Testament (henceforth, "NT") is relatively well-known, the various subcategories of meaning of the concept of 'background', as it applies specifically to Luke, need to be identified and discussed. The study is also new in the sense that it attempts to provide further evidence that the function of the imperfect in Luke's narrative proper is not restricted to background information, but that it can denote foreground in certain circumstances.
Although the function of the few occurrences of the pluperfect in Luke's narrative proper has received some attention, 2 this paper offers a number of new perspectives.

The foreground vs. background distinction in narrative discourse
The foreground vs. background distinction in narrative discourse is defined in a number of ways in literature studies. The definition used in this paper derives mainly from that of Callow (1974: 52-53), 3 who relates foreground to thematic prominence. According to Callow, thematic material "carries the discourse forward, contributes to the progression of the narrative or argument [and] develops the theme of the discourse". Non-thematic or background material "serves as a commentary on the theme but does not itself contribute directly to the progression of the theme […] [It] fills out the theme but does not develop it".
In addition to thematic prominence, a number of other indicators have been proposed for foreground and background in narrative discourse. According to Fleischmann (1985: 857), the "conventional view" in many discourse studies -such as those of Talmy (1978), Hopper (1979aHopper ( , 1979b, and Hopper and Thompson (1980) -is that: those events which constitute the 'main line' of the story are typically encoded as action verbs, aspectually perfective, while supportive material is typically packaged in the form of stative or durative predicates, aspectually imperfective. 4 Other indicators that have been proposed include morphosyntactic devices, involving degrees of transitivity, 5 events vs. non-events, 6 voice, and word order. 7 The indicators are not mutually exclusive, and often co-occur with specific tense-forms of the verb in indicating foreground and background.
In the field of NT studies, considerable research has been undertaken during the last few decades on the foreground-background distinction in narrative discourse and its relationship to specific Greek tense-forms with their accompanying aspectual and time characteristics. This was mostly due to the impetus of the work of Porter (1989) and Fanning (1990) on the aspectual and temporal characteristics of the Greek verb-tenses, and the ensuing upsurge of interest in these areas. 8 In some instances, research was done on extensive corpuses, such as books or chapters of the NT. 9 It is now important to discuss briefly the view of the aspectual and time characteristics of the imperfect and pluperfect tense-forms which is used in this study on narrative proper in Luke.

The imperfect
Scholars generally agree that the aspect of the imperfect is "imperfective". For example, "imperfective aspect" is described by Fanning (1990: 27) as an internal viewpoint "without reference to the beginning or end-point of the action, but with a focus instead on its internal structure or make-up" 10 . This is in contrast with the aorist, of which the aspect is generally viewed as perfective.
However, it should be added that the imperfect has other important characteristics related to its aspect. In a recent paper on the function of imperfect tense-form in narrative discourse in John's Gospel (Du Toit 2017: 215), I drew attention to the view of Seiler (1952: 113) that the imperfect in Modern Greek always establishes a reference to another verbal utterance. 11 Bakker (1966: 26), who applies Seiler's view to NT Greek, defines the "chief characteristic" of the imperfect as follows: "[The imperfect] always has a relationship with another verbal notion, a point from which, around which, or before which the speaker views the process in its perspective". To this should be added the important remarks of Rijksbaron (1988: 237) that the "non-closed" and "ongoing" nature of the imperfect "raises expectations as to what is going to happen next" and "serves as a powerful means to establish cohesion in a text".
With regard to the time-reference of the imperfect, there is no agreement among scholars on whether the imperfect has an inherent characteristic to refer to past time, or whether the reference to the past (in contexts where the imperfect appears) is due to deictic or aspectual features (e.g. remoteness; Du Toit 2017: 218). 12 This issue is not of crucial importance to the present topic, and will not be debated here. In this paper, it is assumed, as in Du Toit (2017: 218), that time-reference is integral to the imperfect in narrative proper, and refers to past time. 8 Cf. Porter (1994: 23), Levinsohn (2000: 169-196), and Campbell (2007Campbell ( , 2008

The pluperfect
The view of the pluperfect's temporal and aspectual characteristics that is used in this paper is formulated by Wallace (1996: 583) as follows: "[…] The force of the pluperfect is that it describes an event that, completed in the past, has results that existed in the past as well (in relation to the time of speaking)" 13 , and "The pluperfect describes the state resulting from the event as continuing" 14 . Wallace distinguishes the following uses of the pluperfect: (i) Intensive pluperfect: According to Wallace (1996: 584), "this use of the pluperfect places the emphasis on the results that existed in past time […] It is different from an imperfect in that the imperfect describes the event itself as progressive, while the pluperfect only describes the state resulting from the event as continuing". Cf. the following examples from Wallace (1996: 584-585), reproduced here in a shortened form: Luke 4:17: τὸν τόπον οὗ ἦν γεγραμμένον ("the place where it was written"), and 4:29: τοῦ ὄρους ἐφ᾽ οὗ ἡ πόλις ᾠκοδόμητο ("of the mountain on which the city was built").

The function of the imperfect and pluperfect to indicate background information
The dominant tense-forms in the indicative mood that occur in narrative discourse in Luke (excluding direct and indirect discourse, and comments by the author) are the aorist (838 times) 15 and imperfect (329 times in its simple, i.e. non-periphrastic, form). 16 There are considerably fewer occurrences of the other tense-forms: the pluperfect occurs 12 times in its simple form, and 4 times in its periphrastic form; the historical present 12 times; and the perfect indicative twice in its simple form. 17 13 The view of the pluperfect as indicating past time is not shared by those linguists who view the Greek verb-tenses as indicating aspect only, not time as well. For example, according to Campbell (2007: 237), the pluperfect "semantically encodes imperfective aspect and heightened remoteness". 14 The view of the pluperfect's aspect as indicating a state is also shared by Porter (1989: 289) and McKay (1994: 322). 15 Statistics based on Campbell (2007: 111). 16 Statistics based on Campbell (2007: 79

Setting the scene 18
Setting the scene, which is by nature a non-event and background information, seems to be the major function of the imperfect in Luke's narrative proper. In this case, one or more imperfects (and/or a pluperfect) provide the setting, after which the main storyline begins, carried by aorist indicatives and/or historical presents. This is illustrated by the passage below (Luke 6:19-31), which is part of Jesus' words introduced by εἶπεν ("he said") in 16:15. This passage is an example of an embedded narrative, in this case, a parable. (In the diagrams below, the following conventions are used: an aorist indicative and its translation are indicated in bold; an imperfect and its translation appear in bold and italics; a pluperfect indicative and its translation are indicated in bold and are single-underlined, and a historical present and its translation appear in bold and are double-underlined.) Luke 16:19-31 19

19
Ἄνθρωπος δέ τις ἦν πλούσιος, καὶ ἐνεδιδύσκετο πορφύραν καὶ βύσσον εὐφραινόμενος καθ᾽ ἡμέραν λαμπρῶς. 19 There was a rich man, and he used to dress in purple and fine linen and celebrated splendidly every day. 20 πτωχὸς δέ τις ὀνόματι Λάζαρος ἐβέβλητο πρὸς τὸν πυλῶνα αὐτοῦ εἱλκωμένος 20 And a certain poor man named Lazarus was laid at his gate, full of sores 21 καὶ ἐπιθυμῶν χορτασθῆναι ἀπὸ τῶν πιπτόντων ἀπὸ τῆς τραπέζης τοῦ πλουσίου· ἀλλὰ καὶ οἱ κύνες ἐρχόμενοι ἐπέλειχον τὰ ἕλκη αὐτοῦ. 21 and longing to fill himself from what fell from the rich man table, and even the dogs would come and lick his sores. 22 ἐγένετο δὲ ἀποθανεῖν τὸν πτωχὸν καὶ ἀπενεχθῆναι αὐτὸν ὑπὸ τῶν ἀγγέλων εἰς τὸν κόλπον Ἀβραάμ· ἀπέθανεν δὲ καὶ ὁ πλούσιος καὶ ἐτάφη. 22 The poor man died and was carried away by the angels to Abraham's bosom. The rich man also died and was buried. 23 καὶ ἐν τῷ ᾅδῃ ἐπάρας τοὺς ὀφθαλμοὺς αὐτοῦ, ὑπάρχων ἐν βασάνοις, ὁρᾷ Ἀβραὰμ ἀπὸ μακρόθεν καὶ Λάζαρον ἐν τοῖς κόλποις αὐτοῦ.  18 The term "setting" is used here to describe the time, place, or circumstances of the mainline events of a narrative (Grimes 1975: 63). 19 The translations of the Greek text in this example and others in the paper are my own. The setting for the story in Luke 16:19-31 begins with the introduction of two major participants. The rich man is introduced in v. 16:19a by ἄνθρωπος δέ τις ἦν πλούσιος ("there was a rich man"), in which the imperfect ἦν ("there was") occurs as the main verb, indicating an ongoing state in the past. 20 The setting continues with a description of the habits of the rich man (v. 19b): καὶ ἐνεδιδύσκετο πορφύραν καὶ βύσσον εὐφραινόμενος καθ᾽ ἡμέραν λαμπρῶς ("and he used to dress in purple and fine linen and celebrated splendidly every day"), which contains the customary imperfect ἐνεδιδύσκετο ("he used to dress") as main verb. The poor man is introduced in v. 20, which contains the pluperfect ἐβέβλητο ("he was laid") as main verb. This is also part of the setting, describing a state in the past that resulted from the action of being laid down at the gate. The setting continues in v. 21, where another customary imperfect ἐπέλειχον ("they [the dogs] would lick") is the main verb. A number of present participles are also used in vv. 19-21, viz. εὐφραινόμενος ("celebrating", v. 19b), ἐπιθυμῶν ("longing", v. 21a), πιπτόντων ("falling", v. 21a), and ἐρχόμενοι ("coming", v. 21b), which could also be regarded as indicating customary actions as part of the setting. The progressive imperfect ἦν ("there was") and the customary imperfects ἐνεδιδύσκετο ("he used to dress", v. 19a) and ἐπέλειχον ("they [the dogs] would lick", v. 21b) fit in well as part of the background setting for the mainline event(s) that follow later on. The imperfects create an expectation of something to happen due to their inherent characteristic of being linked to another verbal utterance. In this way, they contribute to cohesion in the text.
After this general setting, there is a transition in v. 22a, indicated by the use of ἐγένετο ("it happened") and the particle δέ ("and"). 21 The story now moves to more specific background information for the mainline events that follow in vv. 22b-31. The specific background information is provided by the two infinitival clauses: ἀποθανεῖν τὸν πτωχόν ("the poor man died") and ἀπενεχθῆναι αὐτὸν ὑπὸ τῶν ἀγγέλων εἰς τὸν κόλπον Ἀβραάμ ("he was carried away by the angels to Abraham's bosom") in v. 22a. 22 In the main storyline, the focus is first on the death and burial of the rich man (Luke 16:22b-23), and then on the discussion between him and Abraham (vv. 24-31). There is also a concomitant change in the verb-tenses used: whereas imperfects and a pluperfect feature in the broader setting of the narrative (vv. 19-21), the main storyline (vv. 22b-31) is carried by aorist indicatives and historical presents. Two aorist indicatives -ἀπέθανεν ("he died") and ἐτάφη ("he was buried")are used in v. 22b, and five instances of εἶπεν ("he said") in vv. 24-31 to introduce the sections of direct speech in the discussion between the rich man and Abraham. The rest of the main story is carried by historical presents: ὁρᾷ ("he saw", v. 23b) and λέγει ("he said", v. 29).
The overall pattern of the narrative in Luke 16:19-31, where the broader scene is set mainly by imperfects (and one pluperfect), followed by an ἐγένετο-construction indicating specific background circumstances as part of the setting, after which the mainline story commences, occurs in several instances in Luke (cf. also e.g. 5: 15-19ff, 19:47-20:2ff, and 24:13-17f, etc.). 23

Introduction of participants
The introduction of participants, which is also by nature a non-event and as such background information, is done in a number of ways in the NT. 24 Levinsohn (2000: 134) points out that in cases where a participant is introduced in a new section of an ongoing story, a sentence with presentational articulation is most often used. Cf. his example from Acts 9:10a-b: Ἦν δέ τις μαθητὴς ἐν Δαμασκῷ ὀνόματι Ἁνανίας, καὶ εἶπεν πρὸς αὐτὸν ἐν ὁράματι ὁ κύριος· Ἁνανία … ("Now there was a certain disciple in Damascus, named Ananias; and the Lord said to him in a vision, 'Ananias'…"). Ananias is introduced in 9:10a, Ἦν δέ τις μαθητὴς ἐν Δαμασκῷ ὀνόματι Ἁνανίας ("There was a certain disciple in Damascus, named Ananias"), as a participant in the new scene (9:10-18). The sentence in 9:10a has presentational articulation, and the tense-form used is the imperfect ἦν ("there was").
The introduction of participants by means of a sentence with presentational articulation in which the imperfect is used, also occurs in Luke, for example, in 2:36a: Καὶ ἦν Ἅννα προφῆτις, θυγάτηρ Φανουήλ, ἐκ φυλῆς Ἀσήρ ("And there was a prophetess, Anna, the daughter of Phanuel, of the tribe of Asher"). This is followed in 2:36b and 37 by the setting for the main events in v. 38. 25 In the following example from Luke 2:8, the situation is slightly different: Καὶ ποιμένες ἦσαν ἐν τῇ χώρᾳ τῇ αὐτῇ ἀγραυλοῦντες καὶ φυλάσσοντες φυλακὰς τῆς νυκτὸς ἐπὶ τὴν ποίμνην αὐτῶν ("And there were shepherds in the same region staying out in the fields and guarding their flock by night"). This sentence has presentational articulation and contains two periphrastic imperfects -ἦσαν … ἀγραυλοῦντες … φυλάσσοντες ("they were staying out and guarding"). In this case, the introduction of the main participants (the shepherds) and the setting for the mainline story in vv. 9-18 are done in the same sentence. 26 In some instances, the attention prompter ἰδού ("look") is used together with the imperfect in a sentence with presentational articulation, and serves to highlight the introduction of a participant, 27 as in Luke 2:25a: Καὶ ἰδοὺ ἄνθρωπος ἦν ἐν Ἰερουσαλὴμ ᾧ ὄνομα Συμεὼν ("And look, there was a man in Jerusalem called Simeon"). The introduction of Simeon and the first part of the setting are again done in the same clause (2:25a). The rest of the setting occurs in 2.25b-c, and 2:26. In 2.25c, the imperfect ἦν ("he [Simeon] was") is used, and in 2:26, the periphrastic pluperfect ἦν … κεχρηματισμένον ("it had been revealed"). The imperfect in v. 25c is progressive, indicating a state ongoing at the time, and the pluperfect is extensive, meaning that the emphasis is on the "completion of an action in past time, without as much [original italics] on the result" (Wallace 1996: 585). 28 23 The same narrative pattern also occurs in Acts. See e.g. 2:1-4 and 9:31-34. In the Gospel of John, there are considerably fewer occurrences of ἐγένετο ("it happened") -17 in total -, but an example of the pattern occurs in 3:23-36. 24 Cf. Levinsohn (2000: 134-135)

Providing supplementary details
The imperfect and pluperfect often occur in expressions which provide supplementary details. These expressions differ in several respects from those occurring in the setting for a narrative. For example, they occur inside the body of the narrative, and usually refer back to persons, events, etc. in the main storyline. They are usually short, and sometimes parenthetic, expressions. Some of the examples could also be classified as setting the scene. Consider the following passage: Luke 5:8-10b: Summary of background (Luke 5:6-7): After Simon Peter, James, and John had caught a great number of fish, their nets began to break. Their partners in the other boat came to their help. Both boats were filled with fish and began to sink. 8 Ἰδὼν δὲ Σίμων Πέτρος προσέπεσεν τοῖς γόνασιν Ἰησοῦ λέγων· … (Direct discourse) 8 When Simon Peter saw this, he fell down at Jesus' knees and said … (Direct discourse) 9 θάμβος γὰρ περιέσχεν αὐτὸν καὶ πάντας τοὺς σὺν αὐτῷ ἐπὶ τῇ ἄγρᾳ τῶν ἰχθύων ὧν συνέλαβον, 9 For amazement had seized him and all those with him because of the catch of fish which they had taken, 10 ὁμοίως δὲ καὶ Ἰάκωβον καὶ Ἰωάννην υἱοὺς Ζεβεδαίου, οἳ ἦσαν κοινωνοὶ τῷ Σίμωνι. καὶ εἶπεν πρὸς τὸν Σίμωνα ὁ Ἰησοῦς· … (Direct discourse) 10 and so also James and John, the sons of Zebedee, who were partners of Simon. But Jesus said to Simon … (Direct discourse) In this passage, v. 8, which contains the aorist indicative προσέπεσεν ("he [Simon Peter] fell down"), continues the main storyline. Vv. 9 and 10a, which give an explanation for Simon Peter's behaviour and words in v. 8, are a non-event and as such background information. The appositive relative clause οἳ ἦσαν κοινωνοὶ τῷ Σίμωνι ("who were partners of Simon") in v. 10b provides brief supplementary details on the preceding antecedent, Ἰάκωβον καὶ Ἰωάννην ("James and John"). Thereafter, the main storyline, which contains the aorist indicative εἶπεν ("he [Jesus] said"), continues in v. 10c: καὶ εἶπεν πρὸς τὸν Σίμωνα ὁ Ἰησοῦς … ("but Jesus said to Simon …").
In some instances, the mainline story is briefly interrupted by supplementary details on persons who were not the main actors in the scene up to that point, whereafter the focus returns to the mainline story and main actors. Cf. the following passage: Luke 4:16c-21 Summary of background (Luke 4:14-16b): Jesus returned to Galilee and began teaching in synagogues in the region. He came to Nazareth, where he had been brought up. 16c καὶ εἰσῆλθεν κατὰ τὸ εἰωθὸς αὐτῷ ἐν τῇ ἡμέρᾳ τῶν σαββάτων εἰς τὴν συναγωγὴν καὶ ἀνέστη ἀναγνῶναι.
20 He rolled up the book, gave it back to the servant and sat down. The eyes of all in the synagogue were staring at him. 21 ἤρξατο δὲ λέγειν πρὸς αὐτοὺς … (Direct discourse) 21 And he began to say to them … (Direct discourse) In the first part of the mainline story (Luke 4:16c-20a), Jesus is the main actor. In this part, five aorist indicatives are used as main verbs: εἰσῆλθεν ("he went into", v. 16c), ἀνέστη ("he stood up", v. 16c), ἐπεδόθη ("it [the scroll] was given to", v. 17a), εὗρεν ("he found", v. 17b), and ἐκάθισεν ("he sat down", v. 20a). But before the sermon starts in v. 21, the focus moves briefly away from Jesus to the other people in the synagogue in the sentence καὶ πάντων οἱ ὀφθαλμοὶ ἐν τῇ συναγωγῇ ἦσαν ἀτενίζοντες αὐτῷ ("and the eyes of all in the synagogue were staring at him", v. 20b). The sentence contains the periphrastic imperfect ἦσαν ἀτενίζοντες ("they were staring at"), which is progressive, indicating an event taking place at the same time. The function of the sentence is to give supplementary information relating to the behaviour of the other people in the synagogue, and also to introduce them as participants in the rest of the story. Thereafter, the focus returns to the main actor, viz. Jesus, in v. 21.
The pluperfect also occurs a few times in Luke in similar situations, for example, in Luke 23:7-11. In vv. 7-9, the focus is on Herod as the main actor. In v. 10, εἱστήκεισαν δὲ οἱ ἀρχιερεῖς καὶ οἱ γραμματεῖς εὐτόνως κατηγοροῦντες αὐτοῦ ("The chief priests and experts in the Law stood there, vehemently accusing them"), the focus turns briefly to the chief priests and experts in the Law, and then back to Herod again in v. 11. The pluperfect εἱστήκεισαν ("[the chief priest and experts in the Law] stood there") and the participial phrase εὐτόνως κατηγοροῦντες αὐτοῦ ("vehemently accusing him") in v. 10 give brief background information on the behaviour of the chief priests and experts in the Law. The verb εἱστήκεισαν ("stood") belongs to the category of verbs of which the pluperfect has the force of a simple past tense (cf. Wallace: 1996: 586). However, since it is lexically stative, it denotes background information. The same applies to εἱστήκει ("[the crowd] stood") in Luke 23:35a, which appears together with the imperfect ἐξεμυκτήριζον ("[the rulers] ridiculed").
In some instances, a passage contains more than one construction for indicating supplementary details. Cf. the following passage: Luke 23:50-53 Summary of background (Luke 23:48-49): The crowds who had gathered to see the spectacle (i.e. the crucifixion) began to return. Jesus' acquaintances and the women who followed him from Galilee were standing at a distance, watching these things. 50 Καὶ ἰδοὺ ἀνὴρ ὀνόματι Ἰωσὴφ βουλευτὴς ὑπάρχων [καὶ] ἀνὴρ ἀγαθὸς καὶ δίκαιος 50 Now there was a man named Joseph, a member of the Council and a good and righteous man 51 -οὗτος οὐκ ἦν συγκατατεθειμένος τῇ βουλῇ καὶ τῇ πράξει αὐτῶν-ἀπὸ Ἁριμαθαίας πόλεως τῶν Ἰουδαίων, ὃς προσεδέχετο τὴν βασιλείαν τοῦ θεοῦ, 51 -he had not consented to their plan and action -from the Judean town of Arimathaea, who was waiting for the kingdom of God. 52 οὗτος προσελθὼν τῷ Πιλάτῳ ᾐτήσατο τὸ σῶμα τοῦ Ἰησοῦ 52 He went to Pilate and asked for the body of Jesus 53 καὶ καθελὼν ἐνετύλιξεν αὐτὸ σινδόνι καὶ ἔθηκεν αὐτὸν ἐν μνήματι λαξευτῷ οὗ οὐκ ἦν οὐδεὶς οὔπω κείμενος. 53 and after he had taken it down, he wrapped it in a linen cloth and placed it in a tomb hewn out of rock where no one had yet been laid.
In Luke 23:50, the attention prompter ἰδού ("look") highlights the introduction of Joseph, who is a new participant in the story. The flow of the sentence is then interrupted in v. 51a by the parenthetic sentence οὗτος οὐκ ἦν συγκατατεθειμένος τῇ βουλῇ καὶ τῇ πράξει αὐτῶν ("he had not consented to their plan and action"), 29 which refers back to Joseph and provides important supplementary details about his actions. The periphrastic pluperfect ἦν συγκατατεθειμένος ("he consented") in v. 50 could be classified as extensive.
In Luke 23:51c, supplementary details are also given, this time by the appositive relative clause ὃς προσεδέχετο τὴν βασιλείαν τοῦ θεοῦ ("who was waiting for the kingdom of God"). This clause contains the imperfect προσεδέχετο ("he [Joseph] was waiting for"), which refers back and provides details on Joseph in the form of an ongoing state.

Explanation 31
Explanation in narrative is by nature a non-event and as such provides background information. Both the imperfect and the aorist indicative are often used in explanatory clauses in Luke. Cf. the following passage: 29 This sentence is indicated as a parenthesis in the Nestle-Aland 28 text used here, as well as in The Holy Bible: King James Version ([1611], 1769), Die Bybel: 1933/1953translation, The New English Translation (2006, and The New American Standard Bible (1995). Cf. Blass and Debrunner (1967: 243) on parenthetic remarks. Cf. also the reference to Robertson (1919: 904-905, in  also the examples in Acts 9:33 (periphrastic pluperfect) and 18:7 (periphrastic imperfect). The Gospel of John often uses short, independent sentences with an imperfect for this purpose, for example, 1:39: ὥρα ἦν ὡς δεκάτη ("it was the tenth hour"), and 18:10: ἦν δὲ ὄνομα τῷ δούλῳ Μάλχος ("the slave's name was Malchus"), etc. 31 The term "explanation" could be defined as information that "clarifies and explains the events of a narrative" (Levinsohn 2005: 69).
13 But he said to them, "You should give them something to eat." But they said, "We have no more than five loaves and two fish, unless we go and buy food ourselves for all these people." 14 ἦσαν γὰρ ὡσεὶ ἄνδρες πεντακισχίλιοι. εἶπεν δὲ πρὸς τοὺς μαθητὰς αὐτοῦ· … (Direct discourse) 14 For there were about five thousand men. And he said to his disciples … (Direct discourse) The discussion between Jesus and the disciples, which is the mainline story, continues in v. 13, where two aorist indicatives, εἶπεν ("he said") and εἶπαν ("they said"), are used to introduce Jesus' words and the disciples' answer, respectively. This is followed by the short sentence in v. 14a, ἦσαν γὰρ ὡσεὶ ἄνδρες πεντακισχίλιοι ("for there were about five thousand men"), in which the imperfect ἦσαν ("there were") is used. 32 The sentence explains the reason for the disciples' reaction (v. 13d) to the instruction Jesus gave them (v. 13a). 33 Thereafter, the discussion continues in v. 14b, where the aorist indicative εἶπεν ("he said") introduces Jesus' further instructions to the disciples. 34 The only example of a pluperfect in an explanatory clause in Luke's narrative proper seems to be ᾔδεισαν ("they knew") in 4:41 -the verb oἶδα ("I know") belongs to the group of verbs of which the perfect and pluperfect tenses do not have the usual aspectual characteristics, but have a simple present and past force. Since ᾔδεισαν ("they knew") is lexically stative, it denotes background. 35 The aorist indicative is also used in a number of explanatory expressions in Luke, for example, in 5:9, 8:29a, 10:42b, 20:19c, and 22:2b. The aorist indicative differs from the imperfect as the former merely states the occurrence of the event of explanation in the past, whereas the latter signifies an event, state, etc. which is in progress in the past. 32 Some translations treat Luke 9:14a as a parenthesis, enclosing it in brackets. Cf., for example, The New American Standard Bible (1995), New English Translation (2006, and The Holy Bible: The New International Version (2011). 33 The function of the connective γάρ ("for") is "to signal that what follows strengthens a preceding assertion" (Levinsohn 2006: 19).

Use in epilogues 36
An epilogue in narrative discourse is also a non-event by nature and presents background information. The imperfect, but not the pluperfect, occurs in several instances in Luke with this function. Cf. the following passages: Luke 2:39-40 Summary of background (Luke 2:22-38): Jesus' parents had brought him to Jerusalem to present him to the Lord. They were blessed by Simeon. A prophetess, Anna, began to praise God and speak about Jesus.
39 And when they had completed everything according to the law of the Lord, they returned to Galilee, to their own town of Nazareth. 40 Τὸ δὲ παιδίον ηὔξανεν καὶ ἐκραταιοῦτο πληρούμενον σοφίᾳ, καὶ χάρις θεοῦ ἦν ἐπ᾽ αὐτό. 40 And the child continued to grow and became strong, increasing in wisdom, and the grace of God was upon him.
The mainline story continues in Luke 2:39, signalled by the use of two aorist indicativesἐτέλεσαν ("they completed") and ἐπέστρεψαν ("they returned"). In the epilogue of the story (v. 40), a summary is given of Jesus' youth in which three progressive imperfects are used -ηὔξανεν ("he continued to grow"), ἐκραταιοῦτο ("he was becoming strong"), and ἦν ("it [the grace] was").
The use of the imperfects in the epilogue also creates an expectation of something about to happen, and thus promotes cohesion in the text. The events below in Luke 2:41-52, which is about the boy Jesus in the temple, take place 12 years later, and give an example of Jesus' growth and wisdom. This fulfils part of the expectations created by the use of the imperfects in Luke 2:40. However, the structure of the epilogue in this passage is somewhat different.
Luke 2:51-52 The coordinate sentence καὶ κατέβη μετ᾽ αὐτῶν καὶ ἦλθεν εἰς Ναζαρέθ ("and he went down with them and came to Nazareth") in Luke 2:51 is the last part of the mainline story that began in Luke 2:41, and contains the aorist indicatives κατέβη ("he went down") and ἦλθεν ("he came").
The epilogue of the story begins with the sentence καὶ ἦν ὑποτασσόμενος αὐτοῖς ("and he was obedient to them") in Luke 2:51 and ends at the end of v. 52. The epilogue consists of two parts. The first part contains two post-resolution comments about characters in the preceding story, viz.
Jesus and Mary. The first comment, καὶ ἦν ὑποτασσόμενος αὐτοῖς ("and he was obedient to them"), refers to Jesus' behaviour towards his parents after their return to Nazareth, in the aftermath of the events in Jerusalem. The second comment is about Mary -καὶ ἡ μήτηρ αὐτοῦ διετήρει πάντα τὰ ῥήματα ἐν τῇ καρδίᾳ αὐτῆς ("and his mother kept all these events in her heart"). 37 The second part of the epilogue (Luke 2:52) contains a summary of the next period in Jesus' life. The use of the imperfects creates an expectation of something about to happen and promotes cohesion in the text by keeping the story about Jesus running in the background during the following scene where the focus temporarily swings back to John the Baptist (Luke 3:1-20). The story about Jesus is picked up again in v. 3:21 with his baptism 18 years later.
This part of the epilogue is similar in content to the epilogue in Luke 2:40 discussed above, as well as the one in Luke 1:80a -Τὸ δὲ παιδίον ηὔξανεν καὶ ἐκραταιοῦτο πνεύματι ("and the child continued to grow and became strong in spirit") -which follows on the story about the birth of John the Baptist (Luke 1:57-66) and Zechariah's song (Luke 1:67-78).
Only imperfects are used as main verbs in both parts of the epilogue: ἦν ὑποτασσόμενος ("he [Jesus] was obedient") and διετήρει ("she [his mother] kept") in the first part of the epilogue (v. 51), and προέκοπτεν ("he kept increasing") in v. 52. The imperfects are all progressive, indicating states continuing in the past. This fits well with the provision of background information in the epilogue.

The function of the imperfect to indicate foreground information
All the examples discussed so far illustrate the imperfect's ability to indicate various types of background information in Luke's narrative proper. However, there are instances where the imperfect seems to denote foreground. Levinsohn (2000: 174) regards the use of the imperfects in Luke 2:38 as an example of this, and points out that although the imperfect tends to correlate with background information in narrative, "it is not [original italics] a signal that the information concerned is necessarily of a background nature". Luke 2:38 is discussed below in the broader context of Luke 2:36-39.
Luke 2:36-39 Preceding events: After Simeon had blessed Joseph, Mary, and Jesus, he spoke to . This is followed by the passage below. 37 καὶ αὐτὴ χήρα ἕως ἐτῶν ὀγδοήκοντα τεσσάρων, ἣ οὐκ ἀφίστατο τοῦ ἱεροῦ νηστείαις καὶ δεήσεσιν λατρεύουσα νύκτα καὶ ἡμέραν. 37 and she was a widow until she was eighty-four, and did not leave the temple and worshipped day and night with fasting and prayer. 38 καὶ αὐτῇ τῇ ὥρᾳ ἐπιστᾶσα ἀνθωμολογεῖτο τῷ θεῷ καὶ ἐλάλει περὶ αὐτοῦ πᾶσιν τοῖς προσδεχομένοις λύτρωσιν Ἰερουσαλήμ. 38 And at that very moment she came up and began praising God and speaking about him to all who were waiting for the redemption of Jerusalem. 39 Καὶ ὡς ἐτέλεσαν πάντα τὰ κατὰ τὸν νόμον κυρίου, ἐπέστρεψαν εἰς τὴν Γαλιλαίαν εἰς πόλιν ἑαυτῶν Ναζαρέθ. 39 And when they had completed all things according to the law of the Lord, they returned to Galilee, to their city, Nazareth.
A new scene begins in v. 36 in which Anna, the prophetess, is the main actor, and it ends in v. 38. Thereafter, the focus shifts to Joseph, Mary, and Jesus' return to Nazareth (v. 39).
In the story about , all the verbs in the indicative mood are imperfects: v. 36a: ἦν ("there was"), v. 37b: ἀφίστατο ("she left"), and v. 38: ἀνθωμολογεῖτο ("she began praising") and ἐλάλει ("she began speaking"). In v. 36a, the imperfect ἦν ("there was") is used in the introduction of a new participant in the story -viz. the prophetess, Anna -and to set the first part of the scene for the events in v. 38. The scene is further set in v. 36b by means of αὕτη προβεβηκυῖα 38 ἐν ἡμέραις πολλαῖς (lit. "she was advanced in many days") and ζήσασα μετὰ ἀνδρὸς ἔτη ἑπτὰ ἀπὸ τῆς παρθενίας αὐτῆς ("having lived with a husband seven years since the time she was a virgin"). In v. 37, the last part of the scene is set by means of the main clause καὶ αὐτὴ χήρα ἕως ἐτῶν ὀγδοήκοντα τεσσάρων 39 ("and she was a widow until she was eighty-four") in 37a, and the relative clause ἣ οὐκ ἀφίστατο 40 τοῦ ἱεροῦ νηστείαις καὶ δεήσεσιν λατρεύουσα νύκτα καὶ ἡμέραν (lit. "who did not leave the temple and worshipped day and night with fasting and prayer").
In v. 38, two imperfects occur, viz. ἀνθωμολογεῖτο ("she began to worship") and ἐλάλει ("she began to speak"). These are best taken as ingressive, stressing the beginning of the action in the past, with the implication that the action continued for some time. 41 Levinsohn is correct in viewing these imperfects as denoting foreground, especially in view of the fact that v. 38 is the last part of the story about Anna. The events in v. 38 could even be regarded as the climax of the story.

The imperfect
The imperfect is the primary tense-form used in Luke's narrative discourse to give background information. This is related to the imperfect's "imperfective" aspect and characteristic linking to another verbal utterance, which also promotes cohesion in the text. The imperfect gives foreground information in a few instances. This supports the view that the relationship between the imperfect and background information in narrative discourse in Luke is one of correlation rather than strict equivalence.
Setting the scene for events that follow in the mainline story seems to be the main specific use of the imperfect for background information in Luke. A narrative pattern that often occurs in Luke is the setting of the broader scene by one or more imperfects, followed by an ἐγένετοconstruction which indicates a transition and narrows down the setting to more specific circumstances. Thereafter, the mainline story begins, carried by aorist indicatives and/or historical presents. The correlation between the imperfect and background information is particularly strong in cases where the scene is set.
The imperfect is often used to provide supplementary details about persons, events, etc. in the main storyline in the form of short, sometimes parenthetic, expressions which refer back to persons, places, etc. Some of these expressions could also be classified as setting the scene or providing an explanation. They usually do not appear at the beginning of a scene, but inside the body of the main narrative. In a few instances, the mainline story is briefly interrupted by supplementary details about persons who were not the main actors up to that point, whereafter the focus returns to the mainline story and main actors. The aorist indicative is also occasionally used in expressions in Luke that provide supplementary information.
The imperfect also occurs in sentences with presentational articulation to introduce participants in the story. The attention prompter ἰδού ("look") sometimes co-occurs with the imperfect in order to highlight the introduction. In a few instances, the introduction of a participant and the (first part of the) setting are done in the same sentence at the beginning of a scene.
The imperfect occurs only in a few instances in epilogues in Luke. Again, these are nonevents by nature and present background information. The epilogues either consist of postresolution information about characters in the preceding story, or give a summary of what took place afterwards. In some instances, both elements form part of the same epilogue. All the imperfects in the epilogues indicate states that continued in the past. The use of the imperfect in these cases also creates an expectation of something about to happen and thus promotes cohesion in the text.
The imperfect is sometimes used in explanatory clauses. Explanation in narrative is by nature a non-event and as such also provides background information.

The pluperfect
The pluperfect occurs only 16 times in Luke, and indicates background information in all cases. This is related to the pluperfect's characteristic of describing a continuing state in the past which is the result of an event in the past. The pluperfect has the following specific background uses: (i) It occurs in a few instances together with one or more imperfects in setting the scene for the mainline events that follow; (ii) It is used in a number of instances to provide supplementary details about persons, events, etc. in the main storyline. In this use, the pluperfect always refers backwards, for example, when it occurs in an appositive relative clause. In a few instances, the pluperfect provides supplementary details about persons who were not the main actors in the story up to that point, whereafter the focus returns to the mainline story and actors; (iii) The only example of the use of the pluperfect in an explanatory clause in Luke seems to be ᾔδεισαν ("they knew", Luke 4:41). This verb indicates background information, not on account of the pluperfect's usual aspectual characteristics, but because ᾔδεισαν ("they knew") is lexically a stative verb.
