Deuteronomy 13:9-10

ERV(i) 9 but thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people. 10 And thou shalt stone him with stones, that he die; because he hath sought to draw thee away from the LORD thy God, which brought thee out of the land of Egypt, out of the house of bondage.
