Leviticus 24:14-16

“Take outside the camp him who has cursed; then let all who heard him lay their hands on his head, and let all the congregation stone him. “Then you shall speak to the children of Israel, saying: ‘Whoever curses his God shall bear his sin. And whoever blasphemes the name of the LORD shall surely be put to death. All the congregation shall certainly stone him, the stranger as well as him who is born in the land. When he blasphemes the name of the LORD, he shall be put to death.
