Jude 1:4-7

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.

6And the angels—who did not keep their own position of authority but deserted their proper place—He has kept in everlasting shackles under gloomy darkness until the judgment of the great Day.

7In the same way as these angels, Sodom and Gomorrah and the cities around them—having given themselves over to sexual immorality and gone after a different sort of flesh—are displayed as an example, suffering the punishment of eternal fire.
