Deuteronomy 13:9-11 The Message (MSG)
6-10 And when your brother or son or daughter, or even your dear wife or lifelong friend, comes to you in secret and whispers, “Let’s go and worship some other gods” (gods that you know nothing about, neither you nor your ancestors, the gods of the peoples around you near and far, from one end of the Earth to the other), don’t go along with him; shut your ears. Don’t feel sorry for him and don’t make excuses for him. Kill him. That’s right, kill him. You throw the first stone. Take action at once and swiftly with everybody in the community getting in on it at the end. Stone him with stones so that he dies. He tried to turn you traitor against God, your God, the one who got you out of Egypt and the world of slavery.
11 Every man, woman, and child in Israel will hear what’s been done and be in awe. No one will dare to do an evil thing like this again.
