Section 9. The Angel Raphael, the divinely appointed companion and guide of Tobias, conducted him and brought him back safe and sound; saved him from being devoured by an enormous fish; made known to him the extremely useful properties possessed by the liver, gall and heart of the monster; expelled the demon; repressed and fettered his power and prevented him from injuring Tobias; taught the young man the true and legitimate notion and use of matrimony; and finally restored to the elder Tobias the use of his sight.
