'King of Kings' in the Bible

For in his own good time this will be brought about by that blessed and only potentate, King of kings and Lord of lords,

They were singing the song of Moses, the slave of God, and the song of the Lamb, saying. "Great and marvelous are thy works, O Lord God, the Almighty! Righteous and true are thy ways, Thou King of kings!

These will make war against the Lamb, and the Lamb will conquer them, for he is the Lord of lords, and King of kings. And they who are with him are called and faithful and chosen."

And on his robe and on his thigh he has a name written, KING OF KINGS AND LORD OF LORDS
