But let anyone who is moved by this call to mind that when I discussed the question, how it is credible that those primitive men could abstain for so many years from begetting children, two modes of solution were found—either a puberty late in proportion to their longevity, or that the sons registered in the genealogies were not the firstborn, but those through whom the author of the book intended to reach the point aimed at, as he intended to reach Noah by the generations of Seth. So that, if in the generations of Cain there occurs no one whom the writer could make it his object to reach by omitting the firstborns and inserting those who would serve such a purpose, then we must have recourse to the supposition of late puberty, and say that only at some age beyond a hundred years they became capable of begetting children, so that the order of the generations ran through the firstborns, and filled up even the whole period before the deluge, long though it was. It is, however, possible that, for some more secret reason which escapes me, this city, which we say is earthly, is exhibited in all its generations down to Lamech and his sons, and that then the writer withholds from recording the rest which may have existed before the deluge. And without supposing so late a puberty in these men, there might be another reason for tracing the generations by sons who were not firstborns, viz. that the same city which Cain built, and named after his son Enoch, may have had a widely extended dominion and many kings, not reigning simultaneously, but successively, the reigning king begetting always his successor. Cain himself would be the first of these kings; his son Enoch, in whose name the city in which he reigned was built, would be the second; the third Irad, whom Enoch begat; the fourth Mehujael, whom Irad begat; the fifth Methusael, whom Mehujael begat; the sixth Lamech, whom Methusael begat, and who is the seventh from Adam through Cain. But it was not necessary that the firstborn should succeed their fathers in the kingdom, but those would succeed who were recommended by the possession of some virtue useful to the earthly city, or who were chosen by lot, or the son who was best liked by his father would succeed by a kind of hereditary right to the throne. And the deluge may have happened during the lifetime and reign of Lamech, and may have destroyed him along with all other men, save those who were in the ark. For we cannot be surprised that, during so long a period from Adam to the deluge, and with the ages of individuals varying as they did, there should not be an equal number of generations in both lines, but seven in Cain’s, and ten in Seth’s; for as I have already said, Lamech is the seventh from Adam, Noah the tenth; and in Lamech’s case not one son only is registered, as in the former instances, but more, because it was uncertain which of them would have succeeded when he died, if there had intervened any time to reign between his death and the deluge.
But in whatever manner the generations of Cain’s line are traced downwards, whether it be by firstborn sons or by the heirs to the throne, it seems to me that I must by no means omit to notice that, when Lamech had been set down as the seventh from Adam, there were named, in addition, as many of his children as made up this number to eleven, which is the number signifying sin; for three sons and one daughter are added. The wives of Lamech have another signification, different from that which I am now pressing. For at present I am speaking of the children, and not of those by whom the children were begotten. Since, then, the law is symbolized by the number ten—whence that memorable Decalogue—there is no doubt that the number eleven, which goes beyond828 ten, symbolizes the transgression of the law, and consequently sin. For this reason, eleven veils of goat’s skin were ordered to be hung in the tabernacle of the testimony, which served in the wanderings of God’s people as an ambulatory temple. And in that haircloth there was a reminder of sins, because the goats were to be set on the left hand of the Judge; and therefore, when we confess our sins, we prostrate ourselves in haircloth, as if we were saying what is written in the psalm, “My sin is ever before me.”829 The progeny of Adam, then, by Cain the murderer, is completed in the number eleven, which symbolizes sin; and this number itself is made up by a woman, as it was by the same sex that beginning was made of sin by which we all die. And it was committed that the pleasure of the flesh, which resists the spirit, might follow; and so Naamah, the daughter of Lamech, means “pleasure.” But from Adam to Noah, in the line
