Jude 1:4; Jude 1:8; Jude 1:11; Jude 1:19

4 For certain individuals whose condemnation was written about long ago have secretly slipped in among you. They are ungodly people, who pervert the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.
8 In the very same way, on the strength of their dreams these ungodly people pollute their own bodies, reject authority and heap abuse on celestial beings.
11 Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam’s error; they have been destroyed in Korah’s rebellion.
19 These are the people who divide you, who follow mere natural instincts and do not have the Spirit.
