The wording in each Gospel

All four Gospels record the inscription: "THIS IS JESUS THE KING OF THE JEWS" (Matthew 27:37); "THE KING OF THE JEWS" (Mark 15:26); "THIS IS THE KING OF THE JEWS" (Luke 23:38); "JESUS OF NAZARETH THE KING OF THE JEWS" (John 19:19).

Every account contains the same central charge — "THE KING OF THE JEWS" — and none contradicts another; each records a portion of the full title. Taken together the complete inscription reads: "This is Jesus of Nazareth the King of the Jews." The differences are also natural because the title was written in three languages, and the writers were reporting a placard rather than quoting speech.

Who wrote it and why

John records that "Pilate wrote a title, and put it on the cross" (John 19:19). A crucified man’s accusation was customarily displayed; the sign publicly stated the legal charge for the sentence. Matthew calls it "his accusation" set up "over his head" (Matthew 27:37).

The chief priests objected: "Write not, The King of the Jews; but that he said, I am King of the Jews." Pilate refused to alter it: "What I have written I have written" (John 19:21–22). The charge the priests wanted softened stood over the cross as a declaration of fact.

Three languages, read by many

John notes that "the place where Jesus was crucified was nigh to the city: and it was written in Hebrew, and Greek, and Latin" (John 19:20), so "this title then read many of the Jews." Luke likewise records the three languages (Luke 23:38).

Hebrew was the language of the nation, Greek the common tongue of the eastern empire, and Latin the language of Rome — the declaration of Jesus’ kingship was legible to every passer-by at Passover, whatever their origin.
