Mark 14:43-46

And immediately, even as Jesus said this, Judas, one of the twelve disciples, arrived with a crowd of men armed with swords and clubs. They had been sent by the leading priests, the teachers of religious law, and the elders. The traitor, Judas, had given them a prearranged signal: “You will know which one to arrest when I greet him with a kiss. Then you can take him away under guard.” As soon as they arrived, Judas walked up to Jesus. “Rabbi!” he exclaimed, and gave him the kiss. Then the others grabbed Jesus and arrested him.
