Bede the Venerable — as excerpted in the Catena Aurea on Mark 14:32-42

“(ubi sup.) But He prays, that the cup may pass away, to shew that He is very man, wherefore He adds: Take away this cup from me. But remembering why He was sent, He accomplishes the dispensation for which He was sent, and cries out, But not what I will, but what thou wilt. As if He had said, If death can die, without my dying according to the flesh, let this cup pass away; but since this cannot be otherwise, not what I will, but what thou wilt. Many still are sad at the prospect of death, but let them keep their heart right, and avoid death as much as they can; but if they cannot, then let them say what the Lord said for us.”
