Leviticus 24:15-16

King James Version

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

¹⁶ And 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.
