Matthew 20:21 - Ellicott's Commentary On The Whole Bible

The one on thy right hand. — The favour which had already been bestowed might, in some degree, seem to warrant the petition. John was known emphatically as “the disciple whom Jesus loved” (John 13:23; John 19:26; John 20:2), and if we may infer a general practice from that of the Last Supper (John 13:23), he sat near Him at their customary meals. James was one of the chosen three who had been witnesses of the Transfiguration (Matthew 17:1). Both had been marked out for special honour by the new name of the Sons of Thunder (Mark 3:17). The mother might well think that she was but asking for her sons a continuance of what they had hitherto enjoyed. The sternness of our Lord’s words to Peter (Matthew 16:23) might almost justify the thought that his position had been forfeited.
