Moulton & Milligan — Vocabulary of the Greek NT
ἅμα. The adverbial use seen in Mt 20! may be illustrated by P Flor I. 36° (c. iv/a.D., init.) μνηστευσαμένου pov... τὴν ... [θ]υγατέρα ... [ἅ]μα ex νηπίας ἡλικίας, P Oxy VII. 1025}6 (late iii/A.D.) τῶν θεωριῶν ἅμ᾽ αὔ[ρ]ιον ἥτις ἐστὶν τ ἀγομ[έν]ων. For ἅμα = ‘at the same time,” see P Giss I. 138 (ii/A.D.) πέμψεις ἅμα τὰς Y ἐπιστολάς, P Oxy IV. 798 (probably B.C. 183) ds δ᾽ ἂν παραγένωνται οἱ σιτολόγοι ἐπὶ τὴν παράληψιν τῶν σιτικῶν ἀπομετρήσομεν ἅμα καὶ ταῦτα, αἰ. With ἅμα ς. dat. ‘together with,” cf. P Oxy IV. 658}8 (A.D. 250) τῶν ἱερῶν ἐγευσάμην ἅμα τῷ υἱῷ pov, so with a dat. Rein 26!4 (8.6. 104) ἅμα τῆι συγγραφῆι ταύτηι ἀναφερομένηι, P Oxy VI. 975 (i/A-D-) a loan to be repaid ἅμα τῇ ᾿μῇ τρύ[γ]ῃ», P Petr 1. 24 (3) ((. B.C. 249) ἅμα τῆι λοιπῆι ἀγορᾶι ἧι εἰλήφασι ἐγ βασιλικοῦ, P Flor I. 61° (A.D. 210) ἐχειροτονήθην ἅμ᾽ ἄλλοις, 16. 2115 (A.D. 239) ἅμα τοῖς τῆς κώμης δημοσίοις (neuter) πᾶσι. The use of ἅμα therefore as an ‘‘improper” preposition was not unusual. ἀμαθῆής Ξ Paul however prefers to keep it as an adverb, adding σύν (ι Th 417, 519) : for the preposition only Mt 13% is quotable from NT, and even there D adds σύν. We may compare ὁμόσε c. dat. in P Lips Inv 266 (ii/a.D.—Archiv v. 245) ὁμόσε ταῖς ἄλλαις εὐεργεσίαις. Thayer's note that “ἅμα is temporal and ὁμοῦ local, in the main” (from Ammonius), has support from most of our examples. Both usages are illustrated in the Ptolemaic Pathyris papyrus (Archiv il. p» 515 f.) ἐπεὶ γέγρᾳφεν ὁ πατὴρ συνμίσγειν ἄγων τοὺς Κροκοδιλοπολίτας καὶ ὑμᾶς ἅμα, ὀρθῶς ποιήσετε καὶ κεχαρισμένως ἑτοίμους γενέσθαι ὡς ἅμα ἡμῖν συνεξορμήσητε.
