Deuteronomy 13:6-11

VIN(i) 6 "If your brother, your mother's son, or your son or daughter, or the wife you cherish, or your very best friend tries to secretly entice you, saying: 'Let us go and serve other gods, gods neither you nor your fathers have known, 7 Gods of the peoples round about you, near or far, from one end of the earth to the other; 8 neither will to him nor hearken to him; your eye neither pity him nor spare him nor cover for him: 9 but you must surely kill him. Your hand shall be first on him to put him to death, and afterwards the hand of all the people. 10 Stone him to death, because he sought to lure you from the LORD your God who brought you from the land of Egypt, from the land of slavery. 11 »All Israel will hear and be afraid, and will never again do such a wicked thing among you.
