Leviticus 24:14-16

MSB(i) 14 “Take the blasphemer outside the camp, and have all who heard him lay their hands on his head; then have the whole assembly stone him. 15 And you are to tell the Israelites, ‘If anyone curses his God, he shall bear the consequences of his sin. 16 Whoever blasphemes the name of the LORD must surely be put to death; the whole assembly must surely stone him, whether he is a foreign resident or native; if he blasphemes the Name, he must be put to death.
