Deuteronomy 13:6-10

6Even someone in your own family may try to turn you away from the Lord. It may be your own brother, your son or your daughter. It may be your wife whom you love. It may be a friend that you like very much. They may say to you secretly, ‘We should worship other gods.’ Those are gods that you and your ancestors never knew about before.

7They are gods that people who live around you may worship. They may be gods of people who live near to you. They may be gods of people who live anywhere on the earth.

8But never agree with anyone who says that you should worship those gods. Do not even listen to him! Do not feel sorry for him. Do not try to protect him from punishment.

9Instead, you must certainly kill him! You must be the first person to throw stones to kill him. Then everyone else must do the same thing.

10You must throw stones at him until he dies. He tried to turn you away from the Lord your God. It was the Lord who rescued you from Egypt, where you were slaves.
