Leviticus 24:13-16

13Then the Lord spoke to Moses, saying,

14“Bring the one who has cursed [the Lord] outside the camp, and let all who heard him lay their hands on his head [as witnesses to his guilt]; then let all the congregation stone him.

15You shall speak to the Israelites, saying, ‘Whoever curses his God will bear his sin [through his own death].

16Further, the one who blasphemes the name of the Lord shall most certainly be put to death; all the congregation shall stone him. The stranger as well as the native-born shall be put to death when he blasphemes the Name [of the Lord].
