2 Peter 2:15-16

15These false teachers have left the way which is good and right. Like Balaam, Beor's son, they have gone the wrong way. Balaam wanted money so much that he did wrong things to get it.

16But a donkey told him that he was not obeying God. We know that donkeys cannot talk. But that donkey spoke with a human voice. It stopped the prophet Balaam from doing more crazy things.
