Matthew 27:37

The High Priest also in obedience to the letter of the Law wore on his head the writing, 'Holiness to the Lord,' but the true High Priest and King, Jesus, bears on His cross the title, This is the King of the Jews; when ascending to His Father, instead of His own name with its proper letters, He has the Father Himself.

And they set up over his head his accusation written, This is Jesus, the King of the Jews. I cannot sufficiently wonder at the enormity of the thing, that having purchased false witnesses, and having stirred up the unhappy people to riot and uproar, they found no other plea for putting Him to death, than that He was King of the Jews; and this perhaps they set up in mockery.

It was divinely provided that this title should be set up over His head, that the Jews might learn that not even by putting Him to death could they avoid having Him for their King; for in the very instrument of His death He not only did not lose, but rather confirmed His sovereignty.

For because He is at once King and Priest, when He would offer the sacrifice of His flesh on the altar of the cross, His title set forth His regal dignity. And it is set over and not beneath the cross, because though He suffered for us on the cross with the weakness of man, the majesty of the King was conspicuous above the cross; and this He did not lose, but rather confirmed, by the cross.

They parted the garments, by which such great miracles were done. But they wrought none now, Christ restraining His unspeakable power. And this was no small addition of insult. For as to one base and abject, as I said, and the vilest of all men; so do they dare to do all things. To the thieves at any rate they did nothing of the kind, but to Christ they dare it all. And they crucified Him in the midst of them, that He might share in their reputation.
