John Gill Commentary Mark 15:26

"And the superscription of his accusation was written over, THE KING OF THE JEWS." — Mark 15:26 (ASV)

And the superscription of his accusation
Or "the cause of his death", as the Syriac and Persic versions read; the crime for which he suffered:

was written ;
over his head, upon the cross, to which it was fastened; the sum of which was,

the king of the Jews; (See Gill on Matthew 27:37).
