'Blasphemes' in the Bible

Remember how the enemy hurls insults, O Lord, and how a foolish nation blasphemes your name!

I hereby decree that any people, nation, or language group that blasphemes the god of Shadrach, Meshach, or Abednego will be dismembered and his home reduced to rubble! For there exists no other god who can deliver in this way."

But whoever blasphemes against the Holy Spirit will never be forgiven, but is guilty of an eternal sin"

And everyone who speaks a word against the Son of Man will be forgiven, but the person who blasphemes against the Holy Spirit will not be forgiven.
