Jude 1:4-5

4For there are certain men crept in privily, even they who were of old written of beforehand unto this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying our only Master and Lord, Jesus Christ.

5Now I desire to put you in remembrance, though ye know all things once for all, that the Lord, having saved a people out of the land of Egypt, afterward destroyed them that believed not.
