'Blasphemes' in the Bible

Further, the one who blasphemes the name of the Lord shall most certainly be put to death; all the congregation shall stone him. The stranger as well as the native-born shall be put to death when he blasphemes the Name [of the Lord].

But the person who does [anything wrong] willfully and defiantly, whether he is native-born or a stranger, that one is blaspheming the Lord, and that person shall be cut off from among his people [excluding him from the atonement made for them].
