κατισχύω [page 337] This verb, which is very common in the LXX and occurs ter in the NT ( Mat_16:18 , Luk_21:36 , Luk_23:23 ), is construed with the ace. in P Leid W xviii. 3 (ii/iii A.D.) οὐ κατισχύσει με ἅπας δρὰξ κινουμένη , non valebit adversus me omnis pugillus motus (E.d.), much in the same sense as with the gen. in Mt l.c. : cf. also Aristeas 21 τοῦ θεοῦ κατισχύοντος αὐτόν , 230. See Anz Subsidia , p. 295 f., and Durham Menander , p. 70. The verb survives in MGr in the sense prevail, gain the mastery over.
