When he arose from prayer and went back to them, he found them asleep, exhausted from sorrow. "Why are you sleeping?" he asked them. "Get up and pray so that you will not fall into temptation." While he was still speaking a crowd came up, and the man who was called Judas, one of the Twelve, was leading them. He approached Jesus to kiss him, but Jesus asked him, "Judas, are you betraying the Son of Man with a kiss?" When Jesus' followers saw what was going to happen, they said, "Lord, should we strike with our swords?" And one of them struck the servant of the high priest, cutting off his right ear. But Jesus answered, "No more of this!" And he touched the man's ear and healed him. - Luke 22: 45-51 (NIV)
