Moulton & Milligan — Vocabulary of the Greek NT
εὐκαιρέω. The idea of ‘‘favourable opportunity” underlying the word comes out well in P Eleph 297 ἐὰν δὲ μὴ εὐκαιρῇς τ[ο]ῦ διαβῆναι, P Par 4613 (B.c. 153) (= Witkowski’, p. 87) αὐτὸς δέ, ὡς ἂν (cf. Rom 1524, 1 Cor 11%4, Phil 2533) εὐκαιρήσω, παραχρῆμα παρέσομαι πρὸς σέ, P Giss I. 6714 (ii/a.D.) ἐὰν εὐκαιρήσῃ Ἡράκλειος καὶ ἀρετήσηται αὐτοῦ, BGU ΙΝ. 103512 (1st half v/A.D.) Θεὸς οἶδεν ὁ μόνος [ἐὰν οὐκ εὐκέρημε (Δ ηὐκαίρημαι) εἰς ᾿Οξυρύγχων κακὸν εἰχι (2 ἄγχι ᾽) γενέσθαι, and Michel 1499®* (B.c. 171) τοῖς πρεσβευτα]ῖς ἐλθοῦσιν συνέθηκεν, καίπερ οὐκ εὐκαιρῶν. For the meaning ‘have time or leisure,” as in Mk 631 and MGr εὐκαιρέζω, see PSI IV. 42579 (iii/B.c.) εἰ δὲ μὴ εὐκαιρεῖ τις τῶν παρά σοι γραμματέων, ἀπόστειλόν μοι κτλ. : a different meaning is found in 7. 3025 (B.c. 242-1) δοὺς ᾿Αμμωνίωι τῶι κεκομικότι σοι τὴν ἐπιστολὴν ὅσον ἄν ποτε εὐκαιρῆις, Where the editor renders ‘‘ quanto puoi senza disturbo.
