'God of Gods' in the Bible

The king told Daniel, "Truly your God is the God of gods, the Lord of kings, and the Revealer of Secrets, because you were able to reveal this mystery."

""The king will do as he pleases. He'll exalt and magnify himself above every god, speaking amazing things against the God of Gods. He'll succeed until the indignation is completed, because what has been determined must be carried out.
