Luke 22:

47 And while he yet spake, behold a multitude, and he that was called Judas, one of the twelve, went before them, and drew near unto Jesus to kiss him.

48 But Jesus said unto him, Judas, betrayest thou the Son of man with a kiss?

49 When they which were about him saw what would follow, they said unto him, Lord, shall we smite with the sword?

50 And one of them smote the servant of the high priest, and cut off his right ear.

51 And Jesus answered and said, Suffer ye thus far. And he touched his ear, and healed him.
