This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance: This second epistle - In order to guard them against the seductions of false teachers, he calls to their remembrance the doctrine of the ancient prophets, and the commands or instructions of the apostles, all founded on the same basis.
He possibly refers to the prophecies of Enoch, as mentioned by Jude, Jde 1:14, Jde 1:15; of David, Psalms 1:1, etc.; and of Daniel, Daniel 12:2, relative to the coming of our Lord to judgment: and he brings in the instructions of the apostles of Christ, by which they were directed how to prepare to meet their God.
