Deuteronomy 13:9-11

BBE(i) 9 But put him to death without question; let your hand be the first stretched out against him to put him to death, and then the hands of all the people. 10 Let him be stoned with stones till he is dead; because it was his purpose to make you false to the Lord your God, who took you out of the land of Egypt, out of the prison-house. 11 And all Israel, hearing of it, will be full of fear, and no one will again do such evil as this among you.
