Matthew 26:47-49

As 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. [Mark 14:43-50; Luke 22:47-53; John 18:3-11] Now the betrayer had given them a sign, saying, “Whomever I kiss, He is the one; seize Him.” Immediately Judas went to Jesus and said, “Greetings (rejoice), Rabbi!” And he kissed Him [in a deliberate act of betrayal].
