Another story of a devil vanquished by humility.
There was a certain hermit renowned among the monks. It happened that there once met him a man possessed by an evil spirit, who struck him violently upon the cheek. The old man straightway turned to him the other cheek, that he might smite him upon it also. The devil was not able to endure the flame of his humility, but immediately departed from him who was possessed.
