Matthew 26:40

37 And having taken Peter, and the two sons of Zebedee, he began to be sorrowful, and to be very heavy;

38 then saith he to them, `Exceedingly sorrowful is my soul -- unto death; abide ye here, and watch with me.`

39 And having gone forward a little, he fell on his face, praying, and saying, `My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as Thou.`

40 And he cometh unto the disciples, and findeth them sleeping, and he saith to Peter, `So! ye were not able one hour to watch with me!

41 watch, and pray, that ye may not enter into temptation: the spirit indeed is forward, but the flesh weak.`

42 Again, a second time, having gone away, he prayed, saying, `My Father, if this cup cannot pass away from me except I drink it, Thy will be done;`

43 and having come, he findeth them again sleeping, for their eyes were heavy.
