[139] On which account Moses, after he had previously mentioned with respect to Enos that "he hoped to call upon the name of the Lord his God," adds in express words, "This is the book of the generation of men;" [89] speaking with perfect correctness: for it is written in the book of God that man is the only creature with a good hope. So that arguing by contraries, he who has no good hope is not a man. The definition, therefore, of our concrete being is that it is a living rational mortal being; but the definition of man, according to Moses, is a disposition of the soul hoping in the truly living God.
