2 Peter 2:14-16

14They 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.

15Abandoning 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;

16but he was rebuked for his own transgression: a mute donkey spoke with a man’s voice and restrained the prophet’s madness.
