Moulton & Milligan — Vocabulary of the Greek NT
κατισχύω. This verb, which is very common in the LXX and occurs ter in the NT (Mt 1618, Lk 2135, 2325), is construed with the acc. in P Leid W*"!-S (i/iil A.D.) οὐ κατισχύσει pe ἅπας , KQATOLKE® δρὰξ κινουμένη, “‘non valebit adversus me omnis pugillus motus” (Ed.), much in the same sense as with the gen. in Mt Z.c.: cf. also Aristeas 21 τοῦ θεοῦ κατισχύοντος αὐτόν, 230. See Anz Subsidia, p. 295f., and Durham Menander, p. 70. The verb survives in MGr in the sense ‘‘ prevail,” ‘‘ gain the mastery over.
