'God of Gods' in the Bible

The king replied to Daniel, "Certainly your God is a God of gods and Lord of kings and revealer of mysteries, for you were able to reveal this mystery!"

"Then the king will do as he pleases. He will exalt and magnify himself above every deity and he will utter presumptuous things against the God of gods. He will succeed until the time of wrath is completed, for what has been decreed must occur.
