Agony in the Garden
According to all four Gospels, immediately after the Last Supper, Jesus took a walk to pray (John 18:1). Matthew and Mark identify this place of prayer as Gethsemane. Jesus was accompanied by the Apostles Peter, John and James, whom he asked to stay awake and pray. He moved "a stone's throw away" from them, where He felt overwhelming sadness and anguish, and said "My Father, if it is possible, let this cup pass me by. Nevertheless, let it be as you, not I, would have it." Then, a little while later, He said, "If this cup cannot pass by, but I must drink it, your will be done!" (Matthew 26:42). He said this prayer three times, checking on the three apostles between each prayer and finding them asleep. He commented: "The spirit is willing, but the flesh is weak". An angel came from heaven to strengthen him. During his agony as he prayed, "his sweat was as it were great drops of blood falling down upon the ground".(Luke 22:44).
In Roman Catholic tradition the Agony in the Garden is the first Sorrowful Mystery of the Rosary and the Second Station of the Scriptural Way of The Cross. Catholic tradition includes specific prayers and devotions as acts of reparation for the sufferings of Jesus during His Agony and Passion. These Acts of Reparation to Jesus Christ do not involve a petition for a living or dead beneficiary, but aim to repair the sins against Jesus. Some such prayers are provided in the Raccolta Catholic prayer book (approved by a Decree of 1854, and published by the Holy See in 1898) which also includes prayers as Acts of Reparation to the Virgin Mary.
In his encyclical Miserentissimus Redemptor on reparations, Pope Pius XI called Acts of Reparation to Jesus Christ a duty for Catholics and referred to them as "some sort of compensation to be rendered for the injury" with respect to the sufferings of Jesus.
Catholic tradition holds it that the sweating of blood was literal and not figurative.
The Church of Jesus Christ of Latter-day Saints
The Church of Jesus Christ of Latter-day Saints identifies the garden of Gethsemane, in addition to the cross of crucifixion, as the actual location of Jesus' suffering for the sins of the world. Speaking of the Garden, church leader Bruce R. McConkie taught, “this holy ground is where the Sinless Son of the Everlasting Father took upon himself the sins of all men on condition of repentance.” In 1829, church founder, Joseph Smith Jr., recorded a modern revelation from Jesus Christ which reads, “For behold, I, God, have suffered these things for all, that they might not suffer if they would repent; But if they would not repent they must suffer even as I; Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit—and would that I might not drink the bitter cup, and shrink—Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men.”  
In the Catholic tradition, Matthew 26:40 is the basis of the Holy Hour devotion for Eucharistic adoration. In the Gospel of Matthew, Jesus spoke to his disciples, saying "My soul is sorrowful even to death. Remain here and keep watch with me." (Matthew 26:38) Returning to the disciples after prayer, he found them asleep and in Matthew 26:40 he asked Peter:
- "So, could you men not keep watch with me for an hour?".
The tradition of the Holy Hour devotion goes back to 1673 when Saint Margaret Mary Alacoque stated that she had a vision of Jesus in which she was instructed to spend an hour every Thursday night to meditate on the sufferings of Jesus in the Garden of Gethsemane.
