Jude 1:5 - 1:7
5 Now I want to remind you, though you know all things, that Jesus, having once saved a people out of the land of Egypt, subsequently destroyed those who did not believe. 6 And angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day, 7 just as Sodom and Gomorrah and the cities around them, having indulged in the same way as these in gross sexual immorality and having gone after strange flesh, are exhibited as an example in undergoing the punishment of eternal fire.
