Deuteronomy 13:5 NIV

5 That prophet or dreamer must be put to death,1 because he preached rebellion against the LORD your God, who brought you out of Egypt and redeemed you from the land of slavery; he has tried to turn2 you from the way the LORD your God commanded you to follow. You must purge the evil3 from among you.
