Jude (Judah) 1:11-12

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!
