'Blasphemy' in the Bible

And I stood upon the sand of the sea; and I saw a beast rising out of the sea, having ten horns and seven heads, and upon its horns ten diadems, and upon its heads names of blasphemy.

And he carried me away in spirit to a desert; and I saw a woman sitting upon a scarlet beast, full of names of blasphemy, having seven heads and ten horns.
