Deuteronomy 13:17; Deuteronomy 13:5

17 and none of the condemned things are to be found in your hands. Then the LORD will turn from his fierce anger, will show you mercy, and will have compassion on you. He will increase your numbers, as he promised on oath to your ancestors—

5 That prophet or dreamer must be put to death for inciting rebellion against the LORD your God, who brought you out of Egypt and redeemed you from the land of slavery. That prophet or dreamer tried to turn you from the way the LORD your God commanded you to follow. You must purge the evil from among you.
