Deuteronomy
13:6 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, entice you secretly, saying, Let us go and serve other gods, which you have not known, you, nor your fathers;
13:7 of the gods of the peoples who are round about you, near to you, or far off from you, from the one end of the earth even to the other end of the earth;
13:8 you shall not consent to him, nor listen to him; neither shall your eye pity him, neither shall you spare, neither shall you conceal him:
13:9 but you shall surely kill him; your hand shall be first on him to put him to death, and afterwards the hand of all the people.
