Leviticus 24:14-16
14 “Bring the one who has cursed to the outside of the camp and have all who heard him lay their hands on his head; then have the whole community stone him.(A)
15 And tell the Israelites: If anyone curses his God, he will bear the consequences of his sin.
16 Whoever blasphemes the name of Yahweh is to be put to death;(B) the whole community must stone him. If he blasphemes the Name, he is to be put to death, whether the foreign resident or the native.
