'King of Kings' in the Bible

which He will bring about in His own time—He who is the blessed and only Sovereign [the absolute Ruler], the King of those who reign as kings and Lord of those who rule as lords,

They will wage war against the Lamb (Christ), and the Lamb will triumph and conquer them, because He is Lord of lords and King of kings, and those who are with Him and on His side are the called and chosen (elect) and faithful.”

And on His robe and on His thigh He has a name inscribed, “KING OF KINGS, AND LORD OF LORDS.”
