Matthew 26:36-56 (ESV)
Jesus Prays in Gethsemane
36 Then Jesus went with them to a place called Gethsemane, and he said to his disciples, “Sit here, while I go over there and pray.” 37 And taking with him Peter and the two sons of Zebedee, he began to be sorrowful and troubled. 38 Then he said to them, “My soul is very sorrowful, even to death; remain here, and watch  with me.” 39 And going a little farther he fell on his face and prayed, saying, “My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as you will.” 40 And he came to the disciples and found them sleeping. And he said to Peter,“So, could you not watch with me one hour? 41 Watch and pray that you may not enter into temptation. The spirit indeed is willing, but the flesh is weak.” 42 Again, for the second time, he went away and prayed, “My Father, if this cannot pass unless I drink it, your will be done.” 43 And again he came and found them sleeping, for their eyes were heavy. 44 So, leaving them again, he went away and prayed for the third time, saying the same words again. 45 Then he came to the disciples and said to them, “Sleep and take your rest later on.  See, the hour is at hand, and the Son of Man is betrayed into the hands of sinners. 46 Rise, let us be going; see, my betrayer is at hand.”
Betrayal and Arrest of Jesus
47 While he was still speaking, Judas came, one of the twelve, and with him a great crowd with swords and clubs, from the chief priests and the elders of the people. 48 Now the betrayer had given them a sign, saying, “The one I will kiss is the man; seize him.” 49 And he came up to Jesus at once and said, “Greetings, Rabbi!” And he kissed him. 50 Jesus said to him, “Friend, do what you came to do.”  Then they came up and laid hands on Jesus and seized him. 51 And behold, one of those who were with Jesus stretched out his hand and drew his sword and struck the servant  of the high priest and cut off his ear. 52 Then Jesus said to him, “Put your sword back into its place. For all who take the sword will perish by the sword.53 Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels? 54 But how then should the Scriptures be fulfilled, that it must be so?” 55 At that hour Jesus said to the crowds, “Have you come out as against a robber, with swords and clubs to capture me? Day after day I sat in the temple teaching, and you did not seize me. 56 But all this has taken place that the Scriptures of the prophets might be fulfilled.” Then all the disciples left him and fled.
