Deuteronomy 13:8-11

13:8 You must not give in to him or even listen to him; do not feel sympathy for him or spare him or cover up for him. 13:9 Instead, you must kill him without fail! Your own hand must be the first to strike him, and then the hands of the whole community. 13:10 You must stone him to death because he tried to entice you away from the Lord your God, who delivered you from the land of Egypt, that place of slavery. 13:11 Thus all Israel will hear and be afraid; no longer will they continue to do evil like this among you.
