Matthew 26:38

35 Peter saith to him, `Even if it may be necessary for me to die with thee, I will not deny thee;` in like manner also said all the disciples.

36 Then come with them doth Jesus to a place called Gethsemane, and he saith to the disciples, `Sit ye here, till having gone away, I shall pray yonder.`

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.`
