Deuteronomy 13:7-11

of the gods of the peoples who are around you, near you, or far from you, from one end of the earth to the other end),

you shall not consent to him or listen to him; and your eye shall not pity him, nor shall you spare or conceal him.

Instead, you shall most certainly kill him; your hand shall be first against him to put him to death, and afterward the hand of all the people.

So you shall stone him to death, because he has attempted to drive you away from the Lord your God who brought you out of the land of Egypt, out of the house of slavery.

Then all Israel will hear about it and be afraid, and will not do such a wicked thing among you again.
