Moulton & Milligan — Vocabulary of the Greek NT
ταμεῖον, “*(inner) chamber,” ‘‘store-chamber.” The syncopated form ταμεῖον (for ταμιεῖον), which is found in the four NT occurrences of the word (Mt 65, 2435, Lk 12% 33), is the prevailing form in the papyri from i/A.D. onwards: see e.g. CPR I. 178 (a.p. 83-4), tpamét[ys] ταμείω(ν), ‘Sof the bank of the store-houses,” and so*, P Fay 1107 (A.D. 94) ὃ λέγεις ταμε[ἴ]ον, ‘the storehouse you speak of,” BGU παρὰ τῷ ταμείῳ, and 26. VI. 8864 (ili/a.D.) (= Selections, p. 111) ἐν τοῖς τοῦ ‘“Eppod ταμίοις, ‘‘in the archives of Hermes.” In Menander Zap. 18 ταμειΐου probably stands for ταμειδίου. The full form ταμιεῖον is seen in such passages from Ptolemaic times as P Petr II. 32% ° épyat{opévov] μου ἐν τῶι βασιλικῶι ταμιείωι, “as I was working in the Royal Repository” (Edd.), 26. III. 737 (lease of a shop) ταμιεῖον εἰσιόντων ἐνδέξια ὄγδοον, “the eighth shop on the right as one enters’’ (Edd.), and P Hib I. 315 save (c. B.C. 270). From Roman times we can cite BGU I. 106° (a.p. 199) Told] ταμιείου, and P Flor I. 47° (a.p. 213-17) ἐντὸς ταμιείον οἰκίας. See further Thackeray Gr. i. p. 63 ff.
