Deuteronomy 13:6-11

KJ2000(i) 6 If your brother, the son of your mother, or your son, or your daughter, or the wife of your bosom, or your friend, who is as your own soul, entices you secretly, saying, Let us go and serve other gods, which you have not known, you, nor your fathers; 7 Namely, of the gods of the people who are round about you, near unto you, or far off from you, from the one end of the earth even unto the other end of the earth; 8 You shall not yield unto him, nor hearken unto him; neither shall your eye pity him, neither shall you spare, neither shall you conceal him: 9 But you shall surely kill him; your hand shall be first upon him to put him to death, and afterwards the hand of all the people. 10 And you shall stone him with stones, that he die; because he has sought to thrust you away from the LORD your God, who brought you out of the land of Egypt, from the house of bondage. 11 And all Israel shall hear, and fear, and shall do no more any such wickedness as this is among you.
