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.
