1.Now these are the generations of Esau. Though Esau was an alien from the Church in the sight of God; yet since he also, as a son of Isaac, was favored with a temporal blessing, Moses celebrates his race, and inscribes a sufficiently lengthened catalogue of the people born from him. This commemoration, however, resembles an honorable sepulture. For although Esau, with his posterity, took the precedence; yet this dignity was like a bubble, which is comprised under the figure of the world, and which quickly perishes. As, therefore, it has been before said of other profane nations, so now Esau is exalted as on a lofty theater. But since there is no permanent condition out of the kingdom of God, the splendor attributed to him is evanescent, and the whole of his pomp departs like the passing scene of the stage. The Holy Spirit designed, indeed, to testify that the prophecy which Isaac uttered concerning Esau was not vain; but he has no sooner shown its effect, than he turns away our eyes, as if he had cast a veil over it, that we may confine our attention to the race of Jacob. Now, though Esau had children by three wives, in whom afterwards the blessing of God shone forth, yet polygamy is not, on that account, approved, nor the impure lust of man excused: but in this the goodness of God is rather to be admired, which, contrary to the order of nature, gave a good issue to evil beginnings.

6.And went into the country from the face of his brother Jacob. Moses does not mean that Esau departed purposely to give place to his brother; for he was so proud and ferocious, that he never would have allowed himself to seem his brother’s inferior. But Moses, without regard to Esau’s design, commends the secret providence of God, by which he was driven into exile, that the possession of the land might remain free for Jacob alone. Esau removed to Mount Seir, through the desire of present advantage, as is elsewhere stated. Nothing was less in his mind than to provide for his brother’s welfare; but God directed the blind man by his own hand, that he might not occupy that place in the land which he had appointed for his own servant. Thus it often happens that the wicked do good to the elect children of God, contrary to their own intention; and while their hasty cupidity pants for present advantages, they promote the eternal salvation of those whose destruction they have sometimes desired. Let us, then, learn from the passage before us, to see, by the eyes of faith, both in accidental circumstances (as they are called) and in the evil desires of men, that secret providence of God, which directs all events to a result predetermined by himself. For when Esau went forth, that he might live more commodiously apart from his father’s family, he is said to have departed from the face of his brother, because the Lord had so determined it. It is stated indefinitely, that he departed “into the country;” because, being in uncertainty respecting his plan, he sought a home in various places, until Mount Seir presented itself; and as we say, he went out at a venture. ⁽¹²⁹⁾

9.And these are the generations of Esau, the father of the Edomites ⁽¹³⁰⁾ Though Esau had two names, yet in this place the second name refers to his posterity, who are called Idumeans. For, to make it appear what God had bestowed upon him for the sake of his father Isaac, Moses expressly calls him the father of a celebrated and famous people. And certainly, it served this purpose not a little, to trace the effect and fulfillment of the prophecy in the progeny of Esau. For if the promise of God so mightily flourished towards a stranger, how much more powerfully would it put itself forth towards the children, to whom pertaineth the adoption, and consequently the inheritance of grace? Esau was an obscure man, and a sojourner in that country: whence therefore is it, that suddenly rulers should spring from him, and a great body of people should flourish, unless because the benediction which proceeded from the mouth of Isaac, was confirmed by the result? For Esau did not reign in this desert without opposition; since a people of no ignoble name previously inhabited Mount Seir. On this account Moses relates that the men who had before inhabited that land were mighty: so that it would not have been easy for a stranger to acquire such power as Esau possessed, if he had not been divinely assisted.

24.This was that Anah that found the mules. Mules are the adulterous offspring of the horse and the ass. Moses says that Anal was the author of this connection. ⁽¹³¹⁾ But I do not consider this as said in praise of his industry; for the Lord has not in vain distinguished the different kinds of animals from the beginning. But since the vanity of the flesh often solicits the children of this world, so that they apply their minds to superfluous matters, Moses marks this unnatural pursuit in Anah, who did not think it sufficient to have a great number of animals; but he must add to them a degenerate race produced by unnatural intercourse. Moreover, we learn hence, that there is more moderation among brute animals in following the law of nature, than in men, who invent vicious admixtures.
(131) The word ימים, rendered mules by our translators, and by Calvin, is of doubtful signification; it occurs in this place only. It is by many commentators translated “waters,” or “warm springs;” and probably this interpretation is to be preferred. The reader may see the question discussed in Professor Bush’s note on this verse. — Ed

31.These are the kings that reigned, etc We must keep in memory what we have said a little before, that reprobates are suddenly exalted, that they may immediately fall, like the herb upon the roofs, which is destitute of root, and has a hasty growth, but withers the more quickly. To the two sons of Isaac had been promised the honor that kings should spring from them. The Idumeans first began to reign, and thus the condition of Israel seemed to be inferior. But at length, lapse of time taught how much better it is, by creeping on the ground, to strike the roots deep, than to acquire an extravagant pre-eminence for a moment, which speedily vanishes away. There is, therefore, no reason why the faithful, who slowly pursue their way, should envy the quick children of this world, their rapid succession of delights; since the felicity which the Lord promises them is far more stable, as it is expressed in the psalm,
“The children’s children shall dwell there, and their inheritance shall be perpetual.” (Psalms 102:28.)
