John Gill Commentary Luke 22:51

"But Jesus answered and said, Suffer ye [them] thus far. And he touched his ear, and healed him." — Luke 22:51 (ASV)

And Jesus answered and said Not to the question of the disciples, but either to Peter, who had done this rash action; and so the Persic and Ethiopic versions add, "to him"; or else to the multitude, suffer you thus far; and in order to pacify them, "he went to the wounded man", as the Persic version inserts, and he touched his ear and healed him; which shows, that though the human nature of Christ was in a very low condition, yet he still retained the power of doing miracles; and also his great humanity, by which example be confirmed his precept of doing good to enemies; and likewise hereby gave full proof of his willingness to be apprehended by them; for otherwise, he that wrought such a miracle as this, could easily have delivered himself out of their hands; and one would have thought this would have put a stop to them, and have convinced them of the truth of his being a divine person, and the Messiah.
