I. I have conceived the idea of writing the life of Moses, who, according to the account of some persons, was the lawgiver of the Jews, but according to others only an interpreter of the sacred laws, the greatest and most perfect man that ever lived, having a desire to make his character fully known to those who ought not to remain in ignorance respecting him, for the glory of the laws which he left behind him has reached over the whole world, and has penetrated to the very furthest limits of the universe; and those who do really and truly understand him are not many, perhaps partly out of envy, or else from the disposition so common to many persons of resisting the commands which are delivered by lawgivers in different states, since the historians who have nourished among the Greeks have not chosen to think him worthy of mention, the greater part of whom have both in their poems and also in their prose writings, disparaged or defaced the powers which they have received through education, composing comedies and works full of Sybaritish profligacy and licentiousness to their everlasting shame, while they ought rather to have employed their natural endowments and abilities in preserving a record of virtuous men and praiseworthy lives, so that honourable actions, whether ancient or modern, might not be buried in silence, and thus have all recollection of them lost, while they might shine gloriously if duly celebrated; and that they might not themselves have seemed to pass by more appropriate subjects, and to prefer such as were unworthy of being mentioned at all, while they were eager to give a specious appearance to infamous actions, so as to secure notoriety for disgraceful deeds.
