Jamieson, Fausset and Brown on John 19:19-22

19-22. Pilate wrote a title, and put it on the cross ... Jesus of Nazareth, the King of the Jews ... and it was written in Hebrew--or Syro-Chaldaic, the language of the country.

and Greek--the current language.

and Latin--the official language. These were the chief languages of the earth, and this secured that all spectators should be able to read it. Stung by this, the Jewish ecclesiastics entreat that it may be so altered as to express, not His real dignity, but His false claim to it. But Pilate thought he had yielded quite enough to them; and having intended expressly to spite and insult them by this title, for having got him to act against his own sense of justice, he peremptorily refused them. And thus, amidst the conflicting passions of men, was proclaimed, in the chief tongues of mankind, from the Cross itself and in circumstances which threw upon it a lurid yet grand light, the truth which drew the Magi to His manger, and will yet be owned by all the world!
