Lord of kings is one of the Aramaic names for God. It is not found in Hebrew, or in the Greek New Testament; it only occurs in the Aramaic part of the book of Daniel. It was given to God by King Nebuchadnezzar of Babylon.
The name “Lord of kings” expresses God’s supremacy over all the kings of the earth. It is related to other names of God that speak of His supremacy over world rulers: Lord of lords (Deut. 10:17; Ps. 136:3; 1 Tim. 6:15; Rev. 17:14; 19:16) and King of kings (1 Tim. 6:15; Rev. 17:14; 19:16). Jesus Christ is also called the ruler (or prince KJV) of the kings of the earth (Rev. 1:5).
