Leviticus 24:12-16

12They put him in 1custody 2so that 3the command of the Lord might be made clear to them.

13Then the Lord spoke to Moses, saying, 14“Bring the one who has cursed outside the camp, and let all who heard him 4lay their hands on his head; then 5let all the congregation stone him. 15You shall speak to the sons of Israel, saying, ‘6If anyone curses his God, then he will bear his sin. 16Moreover, the one who 7blasphemes the name of the Lord shall surely be put to death; all the congregation shall certainly stone him. The alien as well as the native, when he blasphemes the Name, shall be put to death.
