Jesus celebrates Passover, the Last Supper, and institutes the Lord’s Supper. Judas Iscariot is revealed as the one who will betray Jesus, Jesus prays in Gethsemane.
Now on the first day of Unleavened Bread the disciples came to Jesus, saying, “Where will you have us prepare for you to eat the Passover?” He said, “Go into the city to a certain man and say to him, ‘The Teacher says, My time is at hand. I will keep the Passover at your house with my disciples.'” And the disciples did as Jesus had directed them, and they prepared the Passover (Matthew 26:17-19).
Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, “Take, eat; this is my body.” And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. I tell you I will not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom” (Matthew 26:26-29).
And as they were eating, he said, “Truly, I say to you, one of you will betray me.” And they were very sorrowful and began to say to him one after another, “Is it I, Lord?” He answered, “He who has dipped his hand in the dish with me will betray me. The Son of Man goes as it is written of him, but woe to that man by whom the Son of Man is betrayed! It would have been better for that man if he had not been born.” Judas, who would betray him, answered, “Is it I, Rabbi?” He said to him, “You have said so” (Matthew 26:21-25).
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.” And taking with him Peter and the two sons of Zebedee, he began to be sorrowful and troubled. Then he said to them, “My soul is very sorrowful, even to death; remain here, and watch with me.” 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.” And he came to the disciples and found them sleeping. And he said to Peter, “So, could you not watch with me one hour? Watch and pray that you may not enter into temptation. The spirit indeed is willing, but the flesh is weak.” Again, for the second time, he went away and prayed, “My Father, if this cannot pass unless I drink it, your will be done.” And again he came and found them sleeping, for their eyes were heavy. So, leaving them again, he went away and prayed for the third time, saying the same words again. 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. Rise, let us be going; see, my betrayer is at hand” (Matthew 26:36-46).
 In the “Upper Room” Jesus holds the Last Supper and the apostles receive the bread and wine as his body and blood.
 After the Last Supper, Jesus and his disciples cross the Kidron (or Cedron) Valley just outside Jerusalem, to the western edge of the Mount of Olives. There in the Garden of Gethsemane as he prays, the disciples fall asleep. (Maps of New Testament Story).
