51. ἐπροφήτευσεν for προεφήτευσεν (correction to usual form). In N.T. the better MSS. place the augment before the preposition (Mat 7:22; Mat 11:13; Mat 15:7; Mar 7:6; Luk 1:67; Act 19:6): Jud 1:14 is possibly an exception. Winer, p. 84.
ἤμελλεν for ἔμελλεν: comp. Joh 4:47, Joh 12:33, Joh 18:32. In Joh 6:71 ἔμελλεν is better attested: comp. ἐδύνατο in Joh 11:37. Winer, p. 82.
