Matthew 26:38

35 Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.

36 Then cometh Jesus with them unto a place called Gethsemane, and saith unto the disciples, Sit ye here, while I go and pray yonder.

37 And he took with him Peter and the two sons of Zebedee, and began to be sorrowful and very heavy.

38 Then saith he unto them, My soul is exceeding sorrowful, even unto death: tarry ye here, and watch with me.

39 And he went a little further, 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.

40 And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour?

41 Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.
