And while He yet spake, lo, Judas, one of the twelve, came, and with him a great multitude with swords and staves, from the chief priests and elders of the people. Now he that betrayed Him gave them a sign saying, Whomsoever I shall kiss, the same is he: hold him fast. And forthwith he came to Jesus, and said, Hail, master; and kissed him.
—Matthew 26: 47-49
