John 19:21

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.

Now it was the preparation of the passover. It was about the sixth hour. And he saith to the Jews, Behold your king!

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