John Chrysostom — as excerpted in the Catena Aurea on Mark 10:35-40

“(v. Chrys. ubi sup.) The disciples hearing Christ oftentimes speaking of His kingdom, thought that this kingdom was to be before His death, and therefore now that His death was foretold to them, they came to Him, that they might immediately be made worthy of the honours of the kingdom: wherefore it is said, And James and John, the sons of Zebedee, came unto him, saying, Master, we would that thou shouldest do for us whatsoever we shall desire. For ashamed of the human weakness which they felt, they came to Christ, taking Him apart from the disciples; but our Saviour, not from ignorance of what they wanted to ask, but from a wish of making them answer Him, puts this question to them; And he said unto them, What would ye that I should do for you?”
