2 Peter 2:14-16

They commit adultery with their eyes, and their desire for sin is never satisfied. They lure unstable people into sin, and they are well trained in greed. They live under God’s curse. They have wandered off the right road and followed the footsteps of Balaam son of Beor, who loved to earn money by doing wrong. But Balaam was stopped from his mad course when his donkey rebuked him with a human voice.
