Mark 14:30-40

30 And Jesus said to him, `Verily I say to thee, that to-day, this night, before a cock shall crow twice, thrice thou shalt deny me.'
31 And he spake the more vehemently, `If it may be necessary for me to die with thee -- I will in nowise deny thee;' and in like manner also said they all.
32 And they come to a spot, the name of which [is] Gethsemane, and he saith to his disciples, `Sit ye here till I may pray;'
33 and he taketh Peter, and James, and John with him, and began to be amazed, and to be very heavy,
34 and he saith to them, `Exceeding sorrowful is my soul -- to death; remain here, and watch.'
35 And having gone forward a little, he fell upon the earth, and was praying, that, if it be possible the hour may pass from him,
36 and he said, `Abba, Father; all things are possible to Thee; make this cup pass from me; but, not what I will, but what Thou.'
37 And he cometh, and findeth them sleeping, and saith to Peter, `Simon, thou dost sleep! thou wast not able to watch one hour!
38 Watch ye and pray, that ye may not enter into temptation; the spirit indeed is forward, but the flesh weak.'
39 And again having gone away, he prayed, the same word saying;
40 and having returned, he found them again sleeping, for their eyes were heavy, and they had not known what they might answer him.
