Deuteronomy 13:9-11 Complete Jewish Bible (CJB)
9 (8) you are not to consent, and you are not to listen to him; and you must not pity him or spare him; and you may not conceal him. 10 (9) Rather, you must kill him! Your own hand must be the first one on him in putting him to death, and afterwards the hands of all the people. 11 (10) You are to stone him to death; because he has tried to draw you away from Adonai your God, who brought you out of the land of Egypt, out of a life of slavery.
