2 Peter 2:11-16

whereas even angels who are superior in might and power do not bring a reviling (defaming) accusation against them before the Lord. [Jude 8] But these [false teachers], like unreasoning animals, [mere] creatures of instinct, born to be captured and destroyed, reviling things they do not understand, will also perish in their own corruption [in their destroying they will be destroyed], suffering wrong [destined for punishment] as the wages of doing wrong. They count it a delight to revel in the daytime [living luxuriously]. They are stains and blemishes [on mankind], reveling in their deceptions even as they feast with you. They have eyes full of adultery, constantly looking for sin, enticing and luring away unstable souls. Having hearts trained in greed, [they are] children of a curse. Abandoning the straight road [that is, the right way to live], they have gone astray; they have followed the way of [the false teacher] Balaam the son of Beor, who loved the reward of wickedness; [Num 22:5, 7] but he was rebuked for his own transgression: a mute donkey spoke with a man’s voice and restrained the prophet’s madness. [Num 22:21-31]
