Matthew 26:47-50

47And while he was yet speaking, behold, Judas, one of the twelve, came, and with him a great crowd with swords and sticks from the chief priests and elders of the people.

48Now he that delivered him up had given them a sign, saying, Whomsoever I shall kiss, he it is: seize him.

49And immediately coming up to Jesus he said, Hail, Rabbi, and covered him with kisses.

50But Jesus said to him, [My] friend, for what purpose art thou come? Then coming up they laid hands upon Jesus and seized him.
