Luke 22:51

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

The servant who lost his ear was Malchus (John 18:10); and Luke, with a physician's characteristic observance, noted that it was his right ear.

Suffer ye them thus far ... The word THEM is not in the Greek, and some question exists as to the exact meaning. Geldenhuys understood it as "Let events take their course, even to my arrest,"[33] thus seeing the remark as addressed to the Lord's disciples with the meaning that they should not interfere any further with the arrest.

And healed him ... Like all of the miracles of Jesus, this one had definite and necessary utility. One great purpose of the Lord in the arrest was to procure the exemption of the apostles from custody, as particularly evident in John; but, with Peter's rash act, such would have been far more difficult except for the timely healing of the excised ear.
