In token of a settled separation from the church of God. And here is an account of his posterity, at least the heirs of his family, for seven generations. His son was Enoch, of the same name, but not of the same character with that holy man that walked with God. The names of more of his posterity are mentioned, and but just mentioned, as those of the holy seed, Gen. 5:1-32. They are numbered in haste, as not valued or delighted in, in comparison with God's children.

It has been in cities that the human race has ever made the greatest social progress; and several of Cain's descendants distinguished themselves by their inventive genius in the arts.

She - bare Enoch - As חנוך Chanoch signifies instructed, dedicated, or initiated, and especially in sacred things, it may be considered some proof of Cain’ s repentance, that he appears to have dedicated this son to God, who, in his father’ s stead, might minister in the sacerdotal office, from which Cain, by his crime, was for ever excluded.

17.And Cain knew his wife. From the context we may gather that Cain, before he slew his brother, had married a wife; otherwise Moses would now have related something respecting his marriage; because it would be a fact worthy to be recorded, that any one of his sisters could be found, who would not shrink with horror from committing herself into the hand of one whom she knew to be defiled with a brother’s blood; and while a free choice was still given her, should rather choose spontaneously to follow an exile and a fugitive, than to remain in her father’s family. Moreover, he relates it as a prodigy that Cain, having shaken off the terror he had mentioned, should have thought of having children: ²⁵⁰ for it is remarkable, that he who imagined himself to have as many enemies as there were men in the world, did not rather hide himself in some remote solitude. It is also contrary to nature, that he being astounded with fear; and feeling that God was opposed to him, could enjoy any pleasure. Indeed, it seems to me doubtful, whether he had previously had any children; for there would be nothing absurd in saying, that reference is here made especially to those who were born after the crime was committed, as to a detestable seed who would fully participate in the sanguinary disposition, and the savage manners of their father. This, however, is without controversy, that many persons, as well males as females, are omitted in this narrative; it being the design of Moses only to follow one line of his progeny, until he should come to Lamech. The house of Cain, therefore, was more populous than Moses states; but because of the memorable history of Lamech, which he is about to subjoin, he only adverts to one line of descendents, and passes over the rest in silence.

He built a city. This, at first sight, seems very contrary, both to the judgment of God, and to the preceding sentence. For Adam and the rest of his family, to whom God had assigned a fixed station, are passing their lives in hovels, or even under the open heaven, and seek their precarious lodging under trees; but the exile Cain, whom God had commanded to rove as a fugitive, not content with a private house, builds himself a city. It is, however, probable, that the man, oppressed by an accusing conscience, and not thinking himself safe within the walls of his own house, had contrived a new kind of defense: for Adam and the rest live dispersed through the fields for no other reason, than that they are less afraid. Wherefore, it is a sign of an agitated and guilty mind, that Cain thought of building a city for the purpose of separating himself from the rest of men; yet that pride was mixed with his diffidence and anxiety, appears, from his having called the city after his son. Thus different affections often contend with each other in the hearts of the wicked. Fear, the fruit of his iniquity, drives him within the walls of a city, that he may fortify himself in a manner before unknown; and, on the other hand, supercilious vanity breaks forth. Certainly he ought rather to have chosen that his name should be buried for ever; for how could his memory be transmitted, except to beheld in execration? Yet, ambition impels him to erect a monument to his race in the name of his city. What shall we here say, but that he had hardened himself against punishment, for the purpose of holding out,in inflated obstinacy, against God? Moreover although it is lawful to defend our lives by the fortifications of cities and of fortresses, yet the first origin of them is to be noted, because it is always profitable for us to behold our faults in their very remedies. When captious men sneeringly inquire, whence Cain had brought his architects and workmen to build his city, and whence he sent for citizens to inhabit it? I, in return, ask of them, what authority they have for believing that the city was constructed of squared stones, and with great skill, and at much expense, and that the building of it was a work of long continuance? For nothing further can be gathered from the words of Moses, than that Cain surrounded himself and his posterity with walls formed of the rudest materials: and as it respects the inhabitants; that in that commencement of the fecundity of mankind, his offspring would have grown to so great a number when it had reached his children of the fourth generation, that it might easily form the body of one city.

His wife was probably one of Adam's daughters (Gen 5:4), although it could have been a later descendant, since it would easily have been possible for the population to grow to several hundred thousand by the time of Cain's death.

Cain named his son "Enoch," meaning "dedication" or "commencement," probably signifying the beginning of a new manner of life.

Urbanization is usually considered by evolutionary archaeologists to be one of the first indicators of the emergence of true civilization from a hunting-and-gathering culture (so-called stone age culture). It is significant that true civilized cultures, by this definition, have existed since the very first generation following Adam, with no suggestion of a long evolutionary advance from an imaginary stone age. Evidently Cain, unable to survive either as a farmer or by trade, had to develop his own self-sufficient economy through the patriarchal clan which he established around his son Enoch and the city which Cain built for him."

Enoch : Gen 5:18, Gen 5:22

and he : Gen 11:4; Ecc 2:4-11; Dan 4:30; Luk 17:28, Luk 17:29

Cain knew his wife of which phrase See Poole on "Gen 4:1" .

He built a city partly to divert his troubled mind with business and pleasure, and partly for his own security against the enemies and evils which his guilty conscience made him fear, notwithstanding the assurance which God had given him. And this he did as soon as he was in capacity for it, either by the increase of his own posterity, or by the accession of other degenerate sons of Adam to him, who either being banished, or having departed from the church, willingly associated themselves with their brethren in iniquity.

After the name of his son, Enoch not after his own name, which he knew to be infamous and hateful.

His wife. She was a daughter of Adam, and Cain's own sister; God dispensing with such marriages in the beginning of the world, as mankind could not otherwise be propagated. ---

He built a city, viz. In process of time, when his race was multiplied, so as to be numerous enough to people it. For in the many hundred years he lived, his race might be multiplied even to millions. (Challoner) ---

The Hanuchta, which Ptolemy places in Susiana, (Calmet) may perhaps have been built after the flood, in the same place. Josephus says, Cain was the first who fortified a city; designing it for a retreat, where he might keep the fruits of his robberies, Antiquities 1. 3. Peirere founds his ill-concerted system of Preadamites, or of men existing before Adam, on the history of Cain exercising husbandry, building a city, &c.; as if there were any difficulty in supposing, that the arts would have made some progress in the lapse of above a century. (Haydock)

And Cain knew his wife,.... Who this woman was is not certain, nor whether it was his first wife or not; whether his sister, or one that descended from Adam by another of his sons, since this was about the one hundred and thirtieth year of the creation. At first indeed Cain could marry no other than his sister; but whether he married Abel's twin sister, or his own twin sister, is disputed; the Jews say ^g, that Cain's twin sister was not a beautiful woman, and therefore he said, I will kill my brother and take his wife: on the other hand, the Arabic writers say ^h, that Adam would have had Cain married Abel's twin sister, whom they call Awin; and Abel have married Cain's twin sister, whom they call Azron; but Cain would not, because his own sister was the handsomest; and this they take to be the occasion of the quarrel, which issued in the murder of Abel.

And she conceived and bare Enoch; which signifies "trained up", not in the true religion, and in the ways of God and godliness, as one of this name descending from Seth was, who is said to walk with God; but in the practices of his father Cain, and in a wicked course of life:

and he builded a city: for a settlement on earth, thinking of nothing but this world, and the things of it; or to secure himself from being slain by men; or it may be for his amusement, to divert his thoughts from the melancholy scene always presented to his mind, by being thus employed; and his posterity growing numerous, he took this method to keep them together, and that they might be able to defend themselves from the assaults of others. Some render the words, "he was building a city" ⁱ; as if he did not live to finish it; but it looks as if it was finished by him, by what follows:

and called the name of the city, after the name of his son, Enoch: not after his own name, which was odious and infamous, but after his son's name, to show his affection to him, and that his name might be continued in ages to come; see Psa 49:11. This was the first city that was built, that we read of. Sir Walter Raleigh conjectures ^k that the Henochii or Heniochi of Pliny, Ptolemy, and other writers, took their name from this city of Henoch, or from the country where it stood, when it was repeopled after the flood, since these people were due east from the garden of Eden. (For Cain to marry his sister or any other close relation was not harmful as it is today. There would be few if any genetic disorders at this time. However, as time past, the human race accumulated more and more genetic defects, so by the time of Moses, the laws against incest, as given in Lev 18:1, were necessary. These laws helped prevent deformed children. Ed.)
