For he also was no stranger, but a son, and a brother of the child who had been well pleasing to the father, and he plunged into no ordinary vice, but went to the very extremity, so to say, of evil, he the rich and free and well-bred son being reduced to a more miserable condition than that of household slaves, strangers, and hirelings. Nevertheless he returned again to his original condition, and had his former honour restored to him.
