Deuteronomy 13:6-11

Someone might try to lead you to serve other gods—it might be your brother, your son or daughter, the wife you love, or a close friend. The person might say, “Let’s go and worship other gods.” (These are gods that neither you nor your ancestors have known, gods of the people who live around you, either nearby or far away, from one end of the land to the other.) Do not give in to such people. Do not listen or feel sorry for them, and do not let them go free or protect them. You must put them to death. You must be the first one to start to kill them, and then everyone else must join in. You must throw stones at them until they die, because they tried to turn you away from the LORD your God, who brought you out of the land of Egypt, where you were slaves. Then everyone in Israel will hear about this and be afraid, and no one among you will ever do such an evil thing again.
