Mark 14:43-45

43And immediately, while he was yet speaking, Judas comes up, [being] one of the twelve, and with him a great crowd, with swords and sticks, from the chief priests and the scribes and the elders.

44Now he that delivered him up had given them a sign between them, saying, Whomsoever I shall kiss, that is he; seize him, and lead [him] away safely.

45And being come, straightway coming up to him, he says, Rabbi, Rabbi; and he covered him with kisses.
