Leviticus 24:14-16

“Bring out of the camp the one who cursed, and let all who heard him lay their hands on his head, and let all the congregation stone him. And speak to the people of Israel, saying, Whoever curses his God shall bear his sin. Whoever blasphemes the name of the LORD shall surely be put to death. All the congregation shall stone him. The sojourner as well as the native, when he blasphemes the Name, shall be put to death.
