'King of the Jews' in the Bible

Pilate therefore entered again into the praetorium, 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 person at the passover: will ye therefore that I release unto you the King of the Jews?

and said, Hail, King of the Jews! and they gave him slaps on the face with their hands.

And Pilate also wrote a title, and put it on the cross. And this was the writing: JESUS THE NAZAREAN, THE KING OF THE JEWS,

The chief priests of the Jews then said to Pilate, Write not, The King of the Jews; but that he said, I am King of the Jews.
