εὐκαιρέω [page 262]
The idea of favourable opportunity underlying the word comes out well in P Eleph 29 .7 ἐὰν δὲ μὴ εὐκαιρῇς τ̣[ο ]ῦ διαβῆναι , P Par 46 .18 (B.C. 153) (= Witkowski .2 , p. 87) αὐτὸς δέ , ὡς ἂν (cf. Rom_15:24 , 1Co_11:34 , Php_2:23 ) εὐκαιρήσω , παραχρῆμα παρέσομαι πρὸς σέ , P Giss I. 67 .14 (ii/A.D.) ἐ̣ὰν εὐκαιρήσ̣ῃ Ἠ̣ράκλειο̣ς̣ καὶ ἀρετήση̣ται αὐτοῦ , BGU IV. 1035 .12 (1st half v/A.D.) Θεὸς οἶδεν ὁ .μόνος [ἐ ]ὰν οὐκ εὐκέρημε ( l. ηὐκαίρημαι ) εἰς Ὀξυρύγχων κακὸν ειχι ( l. ἄγχι ?) γενέσθαι , and Michel 1499 B. .4 (B.C. 171) τ [οῖς πρεσβευτα ]ῖς ἐλθοῦσιν συνέθηκεν , καίπερ οὐκ εὐκαιρῶν . For the meaning have time or leisure, as in Mar_6:31 and MGr εὐκαιρέζω , see PSI IV. 425 .29 (iii/B.C.) εἰ δὲ μὴ εὐκαιρεῖ τις τῶν παρά σοι γραμματέων , ἀπόστειλόν μοι κτλ . : a different meaning is found in ib. 392 .9 (B.C. 242 1) δοὺς Ἀμμων̣ι̣ωι τῶι κεκομικότι σοι τὴν ἐπιστολὴν ὅσον ἄν ποτε εὐκαιρῆις , where the editor renders quanto puoi senza disturbo.
