Deuteronomy 13:7-9

Living Bible

^6-7 “If your nearest relative or closest friend, even a brother, son, daughter, or beloved wife whispers to you to come and worship these foreign gods, ⁸ do not consent or listen, and have no pity: Do not spare that person from the penalty; don’t conceal his horrible suggestion. ⁹ Execute him! Your own hand shall be the first upon him to put him to death, then the hands of all the people.
