Deuteronomy - Chapter 10

In verse 17 Moses gives a description of God:

For the Lord your God is God of gods and Lord of lords, the great God, mighty and awesome, who shows no partiality and accepts no bribes.

The same titles are applied to Jesus in the book of Revelation -

Chapter 17, verse 14: Together they will go to war against the Lamb, but the Lamb will defeat them because he is Lord of all lords and King of all kings.

And Chapter 19, verse 16: On his [Jesus'] robe at his thigh was written this title: King of all kings and Lord of all lords.
