John Chrysostom — as excerpted in the Catena Aurea on John 19:19-22

“As letters are inscribed on a trophy declaring the victory, so Pilate wrote a title on Christ’s cross. And Pilate wrote a title, and put it on the cross: thus at once distinguishing Christ from the thieves with Him, and exposing the malice of the Jews in rising up against their King: And the writing was, Jesus of Nazareth, the King of the Jews.”
