Deuteronomy 13:6-10

6“1If your brother, your mother’s son, or your son or daughter, or the wife 2you cherish, or your friend who is as your own soul, entice you secretly, saying, ‘3Let us go and serve other gods’ (whom neither you nor your fathers have known,

7of 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),

84you shall not yield to him or listen to him; 5and your eye shall not pity him, nor shall you spare or conceal him.

96But you shall surely kill him; 7your hand shall be first against him to put him to death, and afterwards the hand of all the people.

10So you shall stone him 8to death because he has sought 9to seduce you from the Lord your God who brought you out from the land of Egypt, out of the house of 10slavery.
