Lucas 22

50 And a certain one of them struck the servant of the high priest, and cut off his right ear!*"The servant of the high priest"—presumably this man was leading the expedition. We know from John 18:10 that his name was Malchus. 51 But Jesus reacted by saying, "Allow at least this!" and touching his ear He healed him.*We know it was Peter (John 18:10), and if the Lord had not healed that ear, things would probably have been nastier for Peter in the ‘courtyard’.
