Deuteronomy 13:6 - 13:11
6 “If your brother, your mother’s son, or your son or daughter, or the wife you cherish, or your friend who is as your own soul, entices you secretly, saying, ‘Let us go and serve other gods’ (whom neither you nor your fathers have known, 7 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), 8 you shall not be willing to accept him or listen to him; and your eye shall not pity him; and you shall not spare him or conceal him. 9 But you shall surely kill him; your hand shall be first against him to put him to death, and afterwards the hand of all the people. 10 So you shall stone him to death because he has sought to drive you from Yahweh your God who brought you out from the land of Egypt, out of the house of slavery. 11 Thus all Israel will hear and be afraid and will never again do such an evil thing among you.
