Jude 1:7-8

Also remember the cities of Sodom and Gomorrah and the other towns around them. In the same way they were full of sexual sin and people who desired sexual relations that God does not allow. They suffer the punishment of eternal fire, as an example for all to see. It is the same with these people who have entered your group. They are guided by dreams and make themselves filthy with sin. They reject God’s authority and speak against the angels.
