Deuteronomy 13:9-11

13:9 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. 13:10 And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage. 13:11 And all Israel shall hear, and fear, and shall do no more any such wickedness as this is among you.
