2 Peter 2:3, 15, 16

In their greed these teachers will exploit you with fabricated stories. Their condemnation has long been hanging over them, and their destruction has not been sleeping.

They have left the straight way and wandered off to follow the way of Balaam son of Bezer, who loved the wages of wickedness.

But he was rebuked for his wrongdoing by a donkey—an animal without speech—who spoke with a human voice and restrained the prophet’s madness.
