289. Hitherto Moses has spoken of the generation of the wicked only, the whole of which he buries as it were with the above brief catalog. The historian now turns to the description of the godly and of the true Church. And first of all, we are to observe the manner of expression Moses uses in reference to the name given by Eve to her son: "And she called his name Seth." Moses does not speak thus concerning Cain when he was born, nor concerning righteous Abel, nor with reference to Enoch, nor with reference to any of the others. By this particular expression regarding Seth and his name Moses would signify that this was the first son in whom flowed the stream of the promise which had been made to the parents in paradise. So Eve is to be understood when she assigns the reason for giving her son this name. Eve manifests her surpassing godliness and faith in giving her son such a name.
290. The fact that Eve recalls the murder by wicked Cain of his brother Abel proves that there had existed a fierce enmity between these two churches, and that she had witnessed and suffered many evils and indignities from the Cainites. Because of this she now called to mind the awful murder which had been committed, whereby Cain wished to destroy the righteous seed that he might reign alone. But thanks be to God, says she, who hath appointed me another seed instead of Abel.
291. Moses here, as is his usual manner, embraces in the fewest possible words the mightiest things, that he may incite the reader to the most diligent consideration of the works of God. Of the pain and righteous grief of the parents at the murder of Abel by his brother we have spoken before. I see no reason why we should not believe that after the perpetration of that horrible murder no son was born to Adam until the birth of Seth; for it is most probable that the awful peril of a recurrence of a calamity like that which they had just experienced, induced the godly parents to abstain from connubial intercourse. I believe, therefore, that by a particular promise made to them by an angel, their minds were again comforted and confirmed, and that they were influenced to believe that a son of the description of Seth would now be born unto them, who should hold fast the promise; and that, although the generation of Cain should utterly perish by their sin, the generation of him about to be born should be preserved until the promised blessed seed should come into the world.
292. It is a proof of some like particular promise having been revealed to the parents by an angel that Eve adds to the name she gave to her son a kind of short sermon, and that Moses when recording this circumstance makes use of an expression not otherwise adopted by him in connection with the names Adam or Eve gave to their children: "And she called his name Seth." Seth is derived from the Hebrew verb sath, which signifies he placed, or he established, and was intended to show that this son would be, as it were, the foundation on which the promise concerning Christ would rest, even though many other sons should be born unto the parents. Eve does not give him an exalted name, such as "Cain," yet she gives him a name signifying that the posterity of Seth should never be suppressed or destroyed.
293. The Cainites, cast out from the sight of their parents, are left under a curse, without any promise whatever, and have only so much mercy as they receive from the generation of the righteous as beggars, not as heirs. This is the mercy we above called uncovenanted mercy. But who, of the posterity of the Cainites, obtained that mercy, Moses does not mention, and his design in this omission is to keep separate the two churches: the one the Church of the righteous, which had the promise of a life to come, but in this life was poor and afflicted; the other the church of the wicked, which in this life is rich and flourishing.
294. Eve, the mother of us all, is highly to be praised, as a most holy woman, full of faith and charity, because in the person of her son Seth she so nobly lauds the true Church, paying no regard whatever to the generation of the Cainites. For she does not say, I have gotten another son in the place of Cain. She prefers the slain Abel to Cain, though Cain was the first-born. Herein praise is due, not only to her faith but to her eminent obedience; for she is not only not offended at the judgment of God concerning righteous Abel, but she also changes her own judgment concerning God. When Abel was born she despised him, and magnified Cain as the first-born, and as the possessor, as she thought, of the promise. But now she acts in all things quite the contrary. As if she had said: After God's acceptance of him and of his offering, I had placed all my hopes on my son Abel, because he was righteous; but his wicked brother slew him. But now God hath appointed me another seed instead of Abel.
