But that discrepancy of numbers which is found to exist between our own and the Hebrew text does not touch the longevity of the ancients; and if there is any diversity so great that both versions cannot be true, we must take our ideas of the real facts from that text out of which our own version has been translated. However, though anyone who pleases has it in his power to correct this version, yet it is not unimportant to observe that no one has presumed to emend the Septuagint from the Hebrew text in the many places where they seem to disagree. For this difference has not been reckoned a falsification; and for my own part I am persuaded it ought not to be reckoned so. But where the difference is not a mere copyist’s error, and where the sense is agreeable to truth and illustrative of truth, we must believe that the divine Spirit prompted them to give a varying version, not in their function of translators, but in the liberty of prophesying. And therefore we find that the apostles justly sanction the Septuagint, by quoting it as well as the Hebrew when they adduce proofs from the Scriptures. But as I have promised to treat this subject more carefully, if God help me, in a more fitting place, I will now go on with the matter in hand. For there can be no doubt that, the lives of men being so long, the firstborn of the first man could have built a city—a city, however, which was earthly, and not that which is called the city of God, to describe which we have taken in hand this great work.

Whether it is credible that the men of the primitive age abstained from sexual intercourse until that date at which it is recorded that they begat children.
Someone, then, will say, Is it to be believed that a man who intended to beget children, and had no intention of continence, abstained from sexual intercourse a hundred years and more, or even, according to the Hebrew version, only a little less, say eighty, seventy, or sixty years; or, if he did not abstain, was unable to beget offspring? This question admits of two solutions. For either puberty was so much later as the whole life was longer, or, which seems to me more likely, it is not the firstborn sons that are here mentioned, but those whose names were required to fill up the series until Noah was reached, from whom again we see that the succession is continued to Abraham, and after him down to that point of time until which it was needful to mark by pedigree the course of the most glorious city, which sojourns as a stranger in this world, and seeks the heavenly country. That which is undeniable is that Cain was the first who was born of man and woman. For had he not been the first who was added by birth to the two unborn persons, Adam could not have said what he is recorded to have said, “I have gotten a man by the Lord.”808 He was followed by Abel, whom the elder brother slew, and who was the first to show, by a kind of foreshadowing of the sojourning city of God, what iniquitous persecutions that city would suffer at the hands of wicked and, as it were, earthborn men, who love their earthly origin, and delight in the earthly happiness of the earthly city. But how old Adam was when he begat these sons does not appear. After this the generations diverge, the one branch deriving from Cain, the other from him whom Adam begot in the room of Abel slain by his brother, and whom he called Seth, saying, as it is written, “For God hath raised me up another seed for Abel whom Cain slew.”809 These two series of generations accordingly, the one of Cain, the other of Seth, represent the two cities in their distinctive ranks, the one the heavenly
