Matthew 26:38-41 King James Version (KJV)
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 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.
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.
