Matthew 26:45-50

45Then he cometh to his disciples, and saith to them, Sleep on now, and take your rest: behold, the hour is at hand, and the Son of man is betrayed into the hands of sinners. 46Rise, let us be going: behold, he is at hand that doth betray me.

47And while he was yet speaking, lo, Judas, one of the twelve, came, and with him a great multitude with swords and staffs, from the chief priests and elders of the people. 48Now he that betrayed him gave them a sign, saying, Whomever I shall kiss, that same is he: hold him fast. 49And immediately he came to Jesus, and said, Hail, master; and kissed him. 50And Jesus said to him, Friend, why art thou come? Then they came, and laid hands on Jesus, and took him.
