Leviticus 24:16-18

"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. And he that killeth any man shall surely be put to death. And he that killeth a beast shall make it good; beast for beast" - Leviticus 24:16-18 KJV
