Jude 1:17

ὑμεῖς δὲ, ἀγαπητοί, μνήσθητε τῶν ῥημάτων τῶν προειρημένων ὑπὸ τῶν ἀποστόλων. The writer turns again, as in Jude 1:20 below, to the faithful members of the Church (Jude 1:3) and reminds them, not now of primeval prophecy, but of warning words uttered by the Apostles. Some have taken this as a quotation by Jude from 2 Peter 3:3, where the quotation is given more fully. But, there also, the words are referred back to a prior authority, “holy prophets” and “your Apostles”. The words ὅτι ἔλεγον ὑμῖν, which follow, imply that the warning was spoken, not written, and that it was often repeated.
