Moulton & Milligan — Vocabulary of the Greek NT
ἀλλάσσω. As so often happens, the simple verb (MGr ἀλλάζω) is outnumbered greatly by its compounds. We may cite Sy/ 1784. (iv/B.c.) κεκτῆσθαι kal ἀλλάσσεσθαι καὶ ἀποδόσθαι, P Oxy IV. γ29 58 (A.D. 137) ἐὰν δὲ αἱρώμεθα ἀλλάσσειν κτήνη ἢ πωλεῖν ἔξεσται ἡμεῖν, Ρ Lips 1. 107% (middle iii/A.p.) ἀλλάξας τὸν λόγον, BGU IV. 11414) 44 (Augustus), where a πορφυρᾶ has been “ bartered,” P Oxy IV. 729" (A.D. 137) in association with πωλεῖν. In P Tebt I. 124} (c. B.c. 118) “εἠλλαγμένοι scems to be equivalent to ἀπηλλαγμένοι rather than to have the meaning ‘exchange’” (Edd.). An illiterate papyrus of A.D. 75 may be cited for the construction: BGU Il. 597'° ἀλλαξέτω σε αὐτὸν (sc. a sack of wheat) Πασίων καλοῖς σπέρμασει. Σέ here is we suppose for σοί: the dative σπέρμασι reminds us of the NT ἐν ὁμοιώματι (Rom 123, from LXX), since the addition of ἐν to a dative is nothing out of the way. (Of course we are not questioning the influence of literal translation here.) The verb is also found in the fragment of the uncanonical Gospel, P Oxy V. 840!" ff τοῦτο τὸ ἱερὸν τόπον ὄν]τα καθαρόν, dv οὐδεὶς ἄΐλλος εἰ μὴ] λουσάμενος Kal ἀλλά[ξας τὰ ἐνδύματα πατεῖ. For the substantive, see P Eleph 14” (late iii/B.C.) τὴν εἰθισμένην ἀλλαγήν : it is fairly common.
