Augustine of Hippo
Catena Aurea · Matthäusevangelium 26
And he went a little farther, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour? Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak. He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done. And he came and found them asleep again: for their eyes were heavy. And he left them, and went away again, and prayed the third time, saying the same words.
(Quæst. Ev. i. 47.) Nor is that an absurd interpretation which makes Our Lord pray thrice because of the threefold temptation of His Passion. To the temptation of curiosity is opposed the fear ofdeath; for as the one is a yearning for the knowledge of things, so the other is the fear of losing such knowledge. To the desire of honour or applause is opposed the dread of disgrace and insult. To the desire of pleasure is opposed the fear of pain.
