'Blasphemous' in the Bible

Then they secretly instigated some men to say, "We have heard this man speaking blasphemous words against Moses and God."

Then I saw a beast coming up out of the sea. It had ten horns and seven heads, and on its horns were ten diadem crowns, and on its heads a blasphemous name.

So he carried me away in the Spirit to a wilderness, and there I saw a woman sitting on a scarlet beast that was full of blasphemous names and had seven heads and ten horns.
