Lc 22:46-51
He said to them, "Why are you sleeping? Get up and pray that you may not undergo the test." While he was still speaking, a crowd approached and in front was one of the Twelve, a man named Judas. He went up to Jesus to kiss him. Jesus said to him, "Judas, are you betraying the Son of Man with a kiss?" His disciples realized what was about to happen, and they asked, "Lord, shall we strike with a sword?" And one of them struck the high priest's servant and cut off his right ear. But Jesus said in reply, "Stop, no more of this!" Then he touched the servant's ear and healed him.
