so and so, and he died," are we to understand that, because it does not name those sons and daughters, therefore, during that long term of years over which one lifetime extended in those early days, there might not have been born very many men, by whose united numbers not one but several cities might have been built? But it suited the purpose of God, by whose inspiration these histories were composed, to arrange and distinguish from the first these two societies in their several generations,--that on the one side the generations of men, that is to say, of those who live according to man, and on the other side the generations of the sons of God, that is to say, of men living according to God, might be traced down together and yet apart from one another as far as the deluge, at which point their dissociation and association are exhibited: their dissociation, inasmuch as the generations of both lines are recorded in separate tables, the one line descending from the fratricide Cain, the other from Seth, who had been born to Adam instead of him whom his brother slew; their association, inasmuch as the good so deteriorated that the whole race became of such a character that it was swept away by the deluge, with the exception of one just man, whose name was Noah, and his wife and three sons and three daughters-in-law, which eight persons were alone deemed worthy to escape from that desolating visitation which destroyed all men. Therefore, although it is written, "And Cain knew his wife, and she conceived and bare Enoch, and he builded a city and called the name of the city after the name of his son Enoch,"[158] it does not follow that we are to believe this to have been his first-born; for we cannot suppose that this is proved by the expression "he knew his wife," as if then for the first time he had had intercourse with her. For in the case of Adam, the father of all, this expression is used not only when Cain, who seems to have been his first-born, was conceived, but also afterwards the same Scripture says, "Adam knew Eve his wife, and she conceived and bare a son, and called his name Seth."[159] Whence it is obvious that Scripture employs this expression neither always when a birth is recorded nor then only when the birth of a first-born is mentioned. Neither is it necessary to suppose that Enoch was Cain's first-born because he named his city after him. For it is quite possible that though he had other sons, yet for some reason the father loved him more than the rest. Judah was not the first-born, though he gives his name to Judæa and the Jews. But even though Enoch was the first-born of the city's founder, that is no reason for supposing that the father named the city after him as soon as he was born; for at that time he, being but a solitary man, could not have founded a civic community, which is nothing else than a multitude of men bound together by some associating tie. But when his family increased to such numbers that he had quite a
