Mathew 26:47-49 And while He was still speaking, behold, Judas, one of the twelve, with a great multitude with swords and clubs, came from the chief priests and elders of the people.
48 Now His betrayer had given them a sign, saying, “Whomever I kiss, He is the One; seize Him.”
49 Immediately he went up to Jesus and said, “Greetings, Rabbi!” and kissed Him.
