Matthew 26:40-42

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.
