Jude 1:4-7

4For certain men have secretly slipped in among you – men who long ago were marked out for the condemnation I am about to describe – ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.

5Now I desire to remind you (even though you have been fully informed of these facts once for all) that Jesus, having saved the people out of the land of Egypt, later destroyed those who did not believe.

6You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.

7So also Sodom and Gomorrah and the neighboring towns, since they indulged in sexual immorality and pursued unnatural desire in a way similar to these angels, are now displayed as an example by suffering the punishment of eternal fire.
