'Blasphemous' in the Bible

And I saw a beast coming up out of the sea. He had 10 horns and seven heads. On his horns were 10 diadems, and on his heads were blasphemous names.

So he carried me away in the Spirit to a desert. I saw a woman sitting on a scarlet beast that was covered with blasphemous names and had seven heads and 10 horns.
