'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].

And some of the scribes said to themselves, “This man blasphemes [by claiming the rights and prerogatives of God]!”

And everyone who speaks a word against the Son of Man, it will be forgiven him; but he who blasphemes against the Holy Spirit [that is, whoever intentionally discredits the Holy Spirit by attributing the authenticating miracles done by Me to Satan], it will not be forgiven him [for him there is no forgiveness].
