Leviticus 24:14-17

¹⁴Bring forth him that hath cursed without the camp; and let all that heard him lay their hands upon his head, and let all the congregation stone him.

¹⁵And thou shalt speak unto the children of Israel, saying, Whosoever curseth his God shall bear his sin.

¹⁶And he that blasphemeth the name of the Lord, he shall surely be put to death, and all the congregation shall certainly stone him: as well the stranger, as he that is born in the land, when he blasphemeth the name of the Lord, shall be put to death.

¹⁷And he that killeth any man shall surely be put to death.
