2 Peter 2:3, 15-16

In their greed they will make up clever lies to get hold of your money. But God condemned them long ago, and their destruction will not be delayed.

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.
