Bible, Old Testament - Leviticus 24:13-16, 23.
13 The Lord said to Moses, saying: 14 Take the blasphemer outside the camp; and let all who were within hearing lay their hands on his head, and let the whole congregation stone him. 15 And speak to the people of Israel, saying: Anyone who curses God shall bear the sin. 16 One who blasphemes the name of the Lord shall be put to death; the whole congregation shall stone the blasphemer. Aliens as well as citizens, when they blaspheme the Name, shall be put to death.
23 Moses spoke thus to the people of Israel; and they took the blasphemer outside the camp, and stoned him to death. The people of Israel did as the Lord had commanded Moses.
