Библейское слово «οὑν» в греческих словарях

οὑν in_crasi = ὁ или οἱ ἐν.

οὖν, ион. дор. ὦν (всегда на втором месте) (обычно с частицами: ἀλλ᾽ οὖν, γὰρ οὖν, δ᾽ οὖν, εἴτε οὖν, καὶ οὖν, μὲν οὖν, οὔτε οὖν, ὥσπερ οὖν)

1) конечно, действительно, именно (так): ἆρ᾽ οὐ τόδε ἦν τὸ δένδρον; — Τοῦτο μὲν οὖν αὐτό Plat. не то ли это дерево? — Да, именно оно самое; ἐγὼ ὥσπερ οὖν οὐκ οἶδα, οὐδὲ οἴομαι Plat. я как в действительности не знаю, так и не думаю, (что знаю); εἴτ᾽ οὖν, εἴτε μὴ γενήσεται Eur. будет это действительно или нет;

2) ну, же: τί οὖν ἦν τοῦτο; Plat. что же такое произошло?; εἴτ᾽ οὖν ἀληθές, εἴτ᾽ οὖν ψεῦδος Plat. будь то правда, будь то ложь;

3) и вот, так вот: τῇ δ᾽ οὖν στρατιᾷ τότε ἀπέδωκε Κῦρος μισθόν Xen. как бы то ни было, но Кир выплатил войску жалование; τῇ τε οὖν αὐτονόμῳ οἰκήσει μετεῖχον οἱ Ἀθηναῖοι Thuc. так вот афиняне жили по собственным законам;

4) всё же: εἰ δὲ μηδέν ἐστι, ἀλλ᾽ οὖν … Plat. если же это и окажется не так, то всё же …;

5) итак, следовательно, поэтому (καὶ γὰρ οὖν ἐπίστευον αὐτῷ οἱ ἄνδρες Xen.): τίς οὖν ὁ λύσων σ᾽ ἐστίν; Aesch. так кто же будет твоим освободителем?;

6) (после pron._relat.) бы ни (было), -либо (см. ὁστισοῦν, ὁποσοσοῦν, ὁποτερωσοῦν и т._п.).

οὖν,
particle

οὖν,
Ionic dialect and Doric dialect ὦν (the latter in [Refs 8th c.BC+], adverb certainly, in fact, confirming something, frequently in contrast with something which is not confirmed, in [Refs 8th c.BC+] only in combination with γε (see. γοῦν), γάρ, οὔτε or μήτε, ὡς, ἐπεί, μέν, etc.:
1 really, φημὶ γὰρ οὖν κατανεῦσαι.. Κρονίωνα for I declare that Zeus did really promise.., [Refs 8th c.BC+]; τόφρα γὰρ οὖν ἑπόμεσθα.., ὄφρ᾽ for we followed them up to the very point, where.., [Refs 8th c.BC+]; ἐλέχθησαν λόγοι ἄπιστοι μὲν ἐνίοισι Ἑλλήνων, ἐλέχθησαν δ᾽ ὦν but they really were spoken, [Refs 5th c.BC+]; Θηβαῖοι μὲν ταῦτα λέγουσι.., Πλαταιῆς δ᾽ οὐχ ὁμολογοῦσι.., ἐκ δ᾽ οὖν τῆς γῆς ἀνεχώρησαν at all events they did return, [Refs 5th c.BC+]; so δ᾽ οὖν after a parenthesis; εἰ δή τις ὑμῶν οὕτως ἔχει,—οὐκ ἀξιῶ μὲν γὰρ ἔγωγε,—εἰ δ᾽ οὖν but if he is so, [Refs 5th c.BC+]; so ἀλλ᾽ οὖν.. γε but at all events, [Refs 5th c.BC+]; ἔμπης οὖν ἐπιμεῖναι ἐς αὔριον to stay nevertheless at least till to-morrow, [Refs 8th c.BC+]; οὖν concessive, I grant you, τάχ᾽ οὖν τις ἄκων ἔσχε [Refs 8th c.BC+]; Τληπόλεμος δ᾽, ἐπεὶ οὖν τράφ᾽ ἐνὶ μεγάρῳ εὐπήκτῳ, αὐτίκα.. κατέκτα when once, i.e. as soon as, he had grown up, [Refs]; νεβροί, αἵ τ᾽ ἐπεὶ οὖν ἔκαμον.. ἑστᾶσ᾽ which, as soon as they are tired, stand still, [Refs]; to indicate that something foreshadowed has actually occurred, ἀγορήνδε καλέσσατο λαὸν Ἀχιλλεύς.., οἱ δ᾽ ἐπεὶ οὖν ἤγερθεν [Refs 8th c.BC+]; τὸν δ᾽ ὡς οὖν ἐνόησε [Refs 8th c.BC+]; οὔτ᾽ οὖν.., οὔτε.. or οὔτε.., οὔτ᾽ οὖν.. both = neither.. nor, but preferred according as the first or second clause is to be marked by emphasis,[Refs 8th c.BC+]; so εἰ.., εἴτ᾽ οὖν.. if.., or if.., [Refs 5th c.BC+]; εἴτ᾽ οὖν, εἴτε μὴ γενήσεται whether it shall be so, or no, [Refs 5th c.BC+]; ξεῖνος αἴτ᾽ ὦν ἀστός, i.e. αἴτε ξ. αἴτ᾽ ὦν ἀ., [Refs 5th c.BC+] even as, just as, [Refs 5th c.BC+]; εἰ δ᾽ ἔστιν, ὥσπερ οὖν ἔστι, θεός if he is, as he in fact is, a god, [Refs 5th c.BC+]; for μὲν οὖν, see at μέν [Refs 5th c.BC+]
2 added to indefinite Prons. and adverbs, like Latin cunque, ὅστις whoever, ὁστισοῦν whosoever; ὅπως how, ὁπωσοῦν howsoever; ἄλλος ὁστισοῦν another, be he who he may; so ὁποιοσοῦν, ὁποιοστισοῦν, ὁποσοσοῦν, ὁπωσδηποτοῦν, ὁπητιοῦν, ὁποθενοῦν, etc., (see entry).
II to continue a narrative, so, then, καὶ τὰ μὲν οὖν.. θῆκαν [Refs 8th c.BC+]; ὅτ᾽ οὖν since, then,.., [Refs 5th c.BC+]; ζεῖ οὖν ἐν τούτῳ.. [Refs 5th c.BC+] is very common in this sense; so δ᾽ οὖν [Refs 5th c.BC+]; οὖν is also used alone merely to resume after a parenthesis or long protasis, well, as I was saying, ὦ Λακεδαιμόνιοι, χρήσαντος τοῦ θεοῦ.., ὑμεας γὰρ πυνθάνομαι προεστάναι..,—ὑμέας ὦν.. προσκαλέομαι.. [Refs 5th c.BC+]
II.2 ὦν is frequently inserted by [Refs 5th c.BC+]participle, οἱ δὲ φέροντες ἐς τὴν ἀγορήν, ἀπ᾽ ὦν ἔδοντο[Refs]; so in [Refs 5th c.BC+]: this tmesis is rare in Attic dialect, ὥστε γε καὐτόν σε κατ᾽ οὖν ἔβαλεν [Refs 5th c.BC+]; but occurs in later writers, Dorieus cited in [Refs 3rd c.BC+]
III in inferences, then, therefore, not in [Refs 8th c.BC+]; in a statement, [Refs]; very common from [Refs 5th c.BC+] downwards; so καὶ σὺ οὖν you too therefore, [Refs 5th c.BC+]; compare οὐ γὰρ οὖν, τοιγαροῦν: strengthened, δὴ οὖν [Refs 5th c.BC+]: in questions, τίς οὖν ὁ λύσων σ᾽ ἐστίν ; [Refs 5th c.BC+], etc.; ἆρ᾽ οὖν δή ; [Refs 5th c.BC+]; τί οὖν δή ; [Refs 5th c.BC+] Источник: STEPBible.org (Tyndale House, Cambridge), CC BY 4.0
