'King of the Jews' in the Bible

Pilate therefore went into the palace again, and called Jesus and said to Him, Art thou the king of the Jews?

and saith unto them, I find no fault at all in Him. But ye have a custom, that I should release to you one at the passover; will ye therefore that I release to you the king of the Jews?

and threw a purple robe about Him, and said, "Hail king of the Jews," and struck Him with their hands.

And Pilate wrote a title, and put it on the cross: and there was written, JESUS OF NAZARETH THE KING OF THE JEWS.

And the chief priests of the Jews said to Pilate, Write not "The king of the Jews," but that "He said, I am king of the Jews."
