Matthew 26:46-50

46Get up, let us go. Look, My betrayer is near!”

47As Jesus was still speaking, Judas [Iscariot], one of the twelve [disciples], came up accompanied by a large crowd with swords and clubs, [who came as representatives] from the chief priests and elders of the people.

48Now the betrayer had given them a sign, saying, “Whomever I kiss, He is the one; seize Him.”

49Immediately Judas went to Jesus and said, “Greetings (rejoice), Rabbi!” And he kissed Him [in a deliberate act of betrayal].

50Jesus said to Judas, “Friend, do what you came for.” Then they came and seized Jesus and arrested Him.
