1 Enoch 9:4
1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed on the earth, and all lawlessness being committed on the earth. 2 And they said to one another: 'The earth, left without inhabitants, cries out, and the voice of their crying reaches the gates of heaven.' 3 'And now to you, the holy ones of heaven, the souls of men plead, saying, "Present our case before the Most High."' 4 And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Your glory stands through all generations, and Your name is holy and glorious and blessed through all ages! 5 You have created all things, and over all things, You have power: all things are open and visible in Your sight, and You see all things, and nothing can hide from You.

And after he had crossed into Europe and was on his way through the whole length of Thrace he nearly lost his army through lack of food and the difficult nature of the land. 7 Consequently he fixed the limits of his expedition in Thrace, and set up stelae in many parts of the regions which he had acquired; and these carried the following inscription in the Egyptian writing which is called "sacred": "This land the King of Kings and Lord of Lords, Sesoösis, subdued with his own arms." 8 And he fashioned the stele with a representation, in case the enemy people were warlike, of the privy parts of a man, but in case they were abject and cowardly, of those of a woman, holding that the quality of the spirit of each people would be set forth most clearly to succeeding generations by the dominant member of the body.
Notes and References
"... “King of kings” (compare 1 Enoch 84:2 and 63:4) is a royal title with a long history in the ancient Near East. In Jewish literature, this title is applied to the God of Israel in contexts that stress his sovereignty over earthly kings. Compare 2 Maccabees 13:4; 3 Maccabees 5:35; Philo Cherubim 99 (compare Special Laws 1.18); mishnah Sanhedrin 4:5 (the king mints coins with his image on them). Thus, the title may be either a claim of sovereignty over other kings or the attribution to God of a title already employed by earthly monarchs ... For the double title, compare Diodorus Siculus 1.55. 7, and the Neo-Babylonian title of Marduk, "Lord of Lords and King of Kings" ..."
