He wrought this miracle both to teach us, that we ought to do good to those who suffer, and to manifest His power. The Evangelist gives the name, that those who then read it might have the opportunity of enquiring into the truth of the account. And he mentions that he was the servant of the high priest, because in addition to the miracle of the cure itself, this shews that it was performed upon one of those who came to take Him, and who shortly after struck Him on the face.
