Moulton & Milligan — Vocabulary of the Greek NT
βοῦς [page 116]
Except in acc. pl., the inflexions are the same as in Attic, e.g. τὴν βοῦν P Par 58 .4 (ii/B.C.) (= Witkowski .2 , p. 80), βοός P Fay 62 .4 (A.D. 134), βόες , βοῶν , βουσί in Mayser Gr. p. 268. For acc. pl. βόας , as in Joh_2:14 f. , see P Oxy IV. 729 .16 (A.D. 137), P Gen I. 48 .32 (A.D. 346); but in Ptolemaic times βοῦς survives in P Petr II. 32 (2 b ) .3 (iii/B.C.). The originally Aeolic dat. βόεσι is found OGIS 200 .15 (iv/A.D.) θρέψαντες αὐτοὺς βόεσιν : it may have been kept alive by poetry. In Ptolemaic papyri the word generally means cow : Mayser gives βοῦς (ἡ ) without citing any cases of ὁ β ., though some are indeterminate. The word is quite rare in NT, as in post-Ptolemaic papyri, and has lost any differentia it once had. As with other words of irregular flexion, diminutives (such as βούδιον , βοΐδιον ) and synonyms encroached upon it. MGr has βούδι (βόδι or βόϊδι ). For φόρος βοῶν , the tax levied on those who kept bulls or cows, see Wilcken Ostr. i. p. 352, and on βουκόλος as a priestly title, as in P Lond 41 .7 (B.C. 161) (= I. p. 27) ὁ βουκόλος τοῦ Ὀσοράπι , see Otto Priester i. p. 110. Βουκόλος is found in its ordinary sense of herdsman in P Flor III. 321 .14f. (iii/A.D.)
