Leviticus 24:14-16

14“Bring the one who has cursed outside the camp, and have all who heard him 1lay their hands on his head; then 2have all the congregation stone him. 15You shall also speak to the sons of Israel, saying, ‘3If anyone curses his God, then he will bear the responsibility for his sin. 16Moreover, the one who 4blasphemes the name of the Lord must be put to death; all the congregation shall certainly stone him. The stranger as well as the native, when he blasphemes the Name, shall be put to death.
