thirty years old when they began to beget children, then, as there are eight generations, including Adam and Lamech's children, 8 times 30 gives 240 years; did they then produce no more children in all the rest of the time before the deluge? With what intention, then, did he who wrote this record make no mention of subsequent generations? For from Adam to the deluge there are reckoned, according to our copies of Scripture, 2262 years,194 and according to the Hebrew text, 1656 years. Supposing, then, the smaller number to be the true one, and subtracting from 1656 years 240, is it credible that during the remaining 1400 and odd years until the deluge the posterity of Cain begat no children?
But let any one 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 first-born, 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 first-borns 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 first-borns, 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 first-borns, 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 first-born 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 first-born 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 beyond195 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."196 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 of Seth, there are ten generations. And to Noah three sons are added, of whom, while one fell into sin, two were blessed by their father; so that, if you deduct the reprobate and add the gracious sons to the number, you get twelve, – a number signalized in the case of the patriarchs and of the apostles, and made up of the parts of the number seven multiplied into one another, – for three times four, or four times three, give twelve. These things being so, I see that I must consider and mention how these two lines, which by their separate genealogies depict the two cities, one of earth-born, the other of regenerated persons, became afterwards so mixed and confused, that the whole human race, with the exception of eight persons, deserved to perish in the deluge.
21. Why it is that, as soon as Cain's son Enoch has been named, the genealogy is forthwith continued as far as the deluge, while after the mention of Enos, Seth's son, the narrative returns again to the creation of man.
We must first see why, in the enumeration of Cain's posterity, after Enoch, in whose name the city was built, has been first of all mentioned, the rest are at once enumerated down to that terminus of which I have spoken, and at which that race and the whole line was destroyed in the deluge; while, after Enos the son of Seth has been mentioned, the rest are not at once named down to the deluge, but a clause is inserted to the following effect: "This is the book of the generations of Adam. In the day that God created man, in the likeness of God made He him; male and female created He them; and blessed them, and called their name Adam, in the day when they were created."197 This seems to me to be inserted for this purpose, that here again the reckoning of the times may start from Adam himself, – a purpose which the writer had not in view in speaking of the earthly city, as if God mentioned it, but did not take account of its duration. But why does he return to this recapitulation after mentioning the son of Seth, the man who hoped to call on the name of the Lord God, unless because it was fit thus to present these two cities, the one beginning with a murderer and ending in a murderer (for Lamech, too, acknowledges to his two wives that he had committed murder), the other built up by him who hoped to call upon the name of the Lord God? For the highest and complete terrestrial duty of the city of God, which is a stranger in this world, is that which was exemplified in the individual who was begotten by him who typified the resurrection of the murdered Abel. That one man is the unity of the whole heavenly city, not yet indeed complete, but to be completed, as this prophetic figure foreshows. The son of Cain, therefore, that is, the son of possession (and of what but an earthly possession?), may have a name in the earthly city which was built in his name. It is of such the Psalmist says, "They call their lands after their own names."198 Wherefore they incur what is written in another psalm: "Thou, O Lord, in Thy city wilt despise their image."199 But as for the son of Seth, the son of the resurrection, let him hope to call on the name of the Lord God. For he prefigures that society of men which says, "But I am like a green olive-tree in the house of God: I have trusted in the mercy of God."200 But let him not seek the empty honours of a famous name upon earth, for "Blessed is the man that maketh the name of the Lord his trust, and respecteth not vanities nor lying follies."201 After having presented the two cities, the one founded in the material good of this world, the other in hope in God, but both starting from a common gate opened in Adam into this mortal state, and both running on and running out to their proper
Eusebius, Jerome, Bede, and others, who follow the Septuagint, reckon only 2242 years, which Vives explains by supposing Augustine to have made a copyist's error.
