Deuteronomy 13:6-9

New International Version

⁶ If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices^(A) you, saying, “Let us go and worship other gods”^(B) (gods that neither you nor your ancestors have known, ⁷ gods of the peoples around you, whether near or far, from one end of the land to the other), ⁸ do not yield^(C) to them or listen to them. Show them no pity.^(D) Do not spare them or shield them. ⁹ You must certainly put them to death.^(E) Your hand^(F) must be the first in putting them to death, and then the hands of all the people.
