Matthew 26:26-41 King James Version (KJV)
26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
30 And when they had sung an hymn, they went out into the mount of Olives.
31 Then saith Jesus unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad.
32 But after I am risen again, I will go before you into Galilee.
33 Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended.
34 Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.
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 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.
