'Blasphemes' in the Bible

Whoever blasphemes the name of Yahweh is to be put to death; 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.

“But the person who acts defiantly, whether native or foreign resident, blasphemes the Lord. That person is to be cut off from his people.

But whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin”—

Anyone who speaks a word against the Son of Man will be forgiven, but the one who blasphemes against the Holy Spirit will not be forgiven.
