John 19:21

So the high priests of the Jews said to Pilate, "Do not write 'King of the Jews,' but 'He said, I am King of the Jews.'"

And it was the day of Preparation for the Passover, about six o'clock in the morning. Then he said to the Jews, "Behold your King!"

And Pilate moreover wrote an inscription and placed it above the cross. What he wrote was, "JESUS, THE NAZARENE, KING OF THE JEWS"

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

Pilate questioned him, "Are you the King of the Jews?" In reply Jesus said, "It is as you say."

For there was an inscription over his head, THIS IS THE KING OF THE JEWS.
