John Chrysostom
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.
That He prays for this a second and a third time, comes of the feelings belonging to human frailty, through which also He feared death, thus giving assurance that He was truly made man. For in Scripture when any thing is repeated a second and third time, that is the greatest proof of its truth and reality; as, for example, when Joseph says to Pharaoh, And for that thou sawedst it twice, it is proof of the thing being established by God. (Gen. 41:32.)
