what does the bible say?
Each of the four Gospels records the inscription on Jesus' cross with slight variation (Matthew 27:37; Mark 15:26; Luke 23:38; John 19:19). Since none of the Gospels gives the full title, this suggests they were summarizing or quoting the part that stood out to them. Additionally, the inscription above Jesus was written in three languages (John 19:20). It is possible that the wording varied across languages, which might also explain the different quotes.
The one portion consistent across all four accounts was that Jesus was “The King of the Jews.” Since they all note this part, it is clear that it was the most important, emphasizing the irony of the Jews killing their promised Messiah-King.
Mark only gives the title of "The King of the Jews". Luke adds, “This is.” Matthew adds, “This is Jesus,” and John adds, “Jesus of Nazareth.” Taken together, the natural reading would be, “This is Jesus of Nazareth, the King of the Jews.”
The “King of the Jews” title was sadly ironic, as the Jews were killing their long-promised King. However, He willingly died, and His death was God’s plan, as it was the only way our sin could be dealt with. The King of the Universe gave His life to bear God’s wrath in our place. Now all who trust in Him for the forgiveness of sins can be saved because of what He accomplished on the cross.
