He then left to make his way as usual to the Mount of Olives, with the disciples following. When they reached the place he said to them, "Pray not to be put to the test."
Then he withdrew from them, about a stone's throw away, and knelt down and prayed. "Father," he said, "if you are willing, take this cup away from me. Nevertheless, let your will be done, not mine." Then an angel appeared to him, coming from heaven to give him strength. In his anguish he prayed even more earnestly, and his sweat fell to the ground like great drops of blood.
Luke 22:39-44
