Moulton & Milligan — Vocabulary of the Greek NT
εὔκαιρος. OGIS 7624 (ii/B.c.) βοηθείτω κατὰ τὸ εὔκαιρον, Michel 16425 (c. B.c. 140) μερίσαι ᾿Απολλωνίωι ξένιον ὅσον ἂν αὐτοῖς εὔκαιρον εἶν]αι φαίνηται. The superlative is found in P Petr II. 12 (1)}5 (B.c. 241) μεταθεῖναι τοὺς βωμοὺς ἐπὶ τοὺς εὐκαιροτάτους τόπους καὶ ἐπιφανεστάτους ἐπὶ τῶν δωμάτων, ‘to remove the altars to the most convenient and conspicuous place on the houses” (Ed.). It may be mentioned that Pallis 4 Few Motes, p. 11 regards the adj. in Mk 674 γενομένης ἡμέρας evkalpov, as = an ““ empty” day, a day without work, a festival; the meaning is supported from Byzantine (see Sophocles Zex. s.v.) and modern Greek.
