De Abrahamo

And God, admiring this man for his faith (πίστις) in him, gives him a pledge (πίστις) in return, namely, a confirmation by an oath of the gifts which he had promised him; no longer conversing with him as God might with man, but as one friend with another. For he says, "By myself have I sworn," [*](Genesis xv. 6. ) by him that is whose word is an oath, in order that Abraham’s mind may be established still more firmly and immoveably than before.

Let the virtuous man both be and be called the elder and the first, and let every fool be called the younger and the last, since he only pursues such objects as may produce revolution and as are placed in the lowest rank.

Thus much is sufficient to say on this subject. But God, adding to the multitude and magnitude of the praises of the wise man one single thing as a crowning point, says that "this man fulfilled the divine law, and all the commandments of God," [*](Genesis xxvi. 5. ) not having been taught to do so by written books, but in accordance with the unwritten law of his nature, being anxious to obey all healthful and salutary impulses. And what is the duty of man except most firmly to believe those things which God asserts?

Such is the life of the first author and founder of our nation; a man according to the law, as some persons think, but, as my argument has shown, one who is himself the unwritten law and justice of God. [*](Genesis xv. 6. ) [*](Genesis xxvi. 5. )
