Leviticus 24:14-16

“Take the blasphemer outside the camp, and tell all those who heard the curse to lay their hands on his head. Then let the entire community stone him to death. Say to the people of Israel: Those who curse their God will be punished for their sin. Anyone who blasphemes the Name of the LORD must be stoned to death by the whole community of Israel. Any native-born Israelite or foreigner among you who blasphemes the Name of the LORD must be put to death.
