Leviticus 24:15-16

And thou shalt speake vnto the children of Israel, saying, Whosoeuer curseth his God, shall beare his sinne.

And he that blasphemeth the name of the Lord, shalbe put to death: all the Congregation shall stone him to death: aswell the stranger, as he that is borne in the lande: when he blasphemeth the name of the Lord, let him beslaine.
