'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?

But ye have a custom that I should release to you one at the passover: do ye desire, therefore, that I release to you the king of the Jews?

and said, Hail, king of the Jews! and they gave him blows on the face.

And Pilate wrote an inscription also, and put it on the cross. And the writing was, "Jesus the Nazarene, the king of the Jews."

Therefore 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.
