Mark 14:44-47

Now His betrayer had given them a signal, saying, “Whomever I kiss, He is the One; seize Him and lead Him away safely.” As soon as he had come, immediately he went up to Him and said to Him, “Rabbi, Rabbi!” and kissed Him. Then they laid their hands on Him and took Him. And one of those who stood by drew his sword and struck the servant of the high priest, and cut off his ear.
