Matthew 26:49

47And 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.

48Now he that betrayed him gave them a sign, saying, Whomsoever I shall kiss, that same is he: hold him fast.

49And forthwith he came to Jesus, and said, Hail, master; and kissed him.

50And Jesus said unto him, Friend, wherefore art thou come? Then came they, and laid hands on Jesus and took him.

51And, behold, one of them which were with Jesus stretched out his hand, and drew his sword, and struck a servant of the high priest’s, and smote off his ear.
