Jude 1:4-5

4For certain people have secretly slipped in—those who from long ago have been marked out for this judgment. They are ungodly people, who pervert the grace of our God into indecency and deny our only Master and Lord, Yeshua the Messiah.

5Now I wish to remind you—though you have come to know all things —that the Lord, once having saved a people out of the land of Egypt, afterward destroyed those who did not believe.
