Jude (Judah) 1:10-13, 16

These people insult anything they don’t understand. They behave like irrational beasts by doing whatever they feel like doing. Because they live by their animal instincts, they corrupt themselves and bring about their own destruction. How terrible it is for them! For they have followed in the steps of Cain. They have abandoned themselves to Balaam’s error because of their greedy pursuit of financial gain. And since they have rebelled like Korah rebelled, they will experience the same fate of Korah and likewise perish. These false teachers are like dangerous hidden reefs at your love feasts, lying in wait to shipwreck the immature. They feast among you without reverence, having no shepherd but themselves. They are clouds with no rain, swept along by the winds. Like fruitless late-autumn trees —twice dead, barren, and plucked up by the roots! They are wild waves of the sea, flinging out the foam of their shame and disgrace. They are misleading like wandering stars, for whom the complete darkness of eternal gloom has been reserved.

These people are always complaining and never satisfied—finding fault with everyone. They follow their own evil desires and their mouths speak scandalous things. They enjoy using seductive flattery to manipulate others.
