Jude 1:5-7

Common(i) 5 Now I desire to remind you, though you were once for all fully informed, that the Lord who saved a people out of the land of Egypt, afterward destroyed those who did not believe. 6 And the angels who did not keep their own domain, but abandoned their proper abode, he has kept in eternal chains under darkness for the judgment of the great day, 7 just as Sodom and Gomorrah and the surrounding cities, which likewise acted immorally and indulged in strange flesh, serve as an example by undergoing a punishment of eternal fire.
