Luke 22:48

45 When he rose up from his prayer, he came to the disciples, and found them sleeping because of grief,

46 and said to them, "Why do you sleep? Rise and pray that you may not enter into temptation."

47 While he was still speaking, behold, a multitude, and he who was called Judas, one of the twelve, went in front of them. He came near to Jesus to kiss him.

48 But Jesus said to him, "Judas, do you betray the Son of Man with a kiss?"

49 When those who were around him saw what was about to happen, they said, "Lord, shall we strike with the sword?"

50 A certain one of them struck the servant of the high priest, and cut off his right ear.

51 But Jesus answered, "Let me at least do this" -- and he touched his ear, and healed him.
