The elder shall serve the younger See how the Lord makes a difference between the sons of Isaac, while they were as yet in their mother's womb; for this was the heavenly answer, by which it appeared that God designed to show to the younger peculiar favor, which he denied to the elder. Though this indeed had reference to the right of primogeniture, yet in this, as the symbol of something greater, was manifested the will of God: and that this was the case we may easily perceive, when we consider what little benefit, according to the flesh, Jacob derived from his primogeniture. For he was, on its account, exposed to great danger; and to avoid this danger, he was obliged to quit his home and his country, and was unkindly treated in his exile: when he returned, he tremblingly, and in doubt of his life, prostrated himself at the feet of his brother, humbly asked forgiveness for his offence, and lived through the indulgence shown to him. Where was his dominion over his brother, from whom he was constrained to seek by entreaty his life? There was then something greater than the primogeniture promised in the answer given by the Lord.

It was said unto her - By Yahweh; see Genesis 25:23.
The elder - The oldest son, which was Esau. By the law of primogeniture among the Hebrews, he would have been entitled to special honors and privileges. But it was said that in his case this custom should be reversed, and that he should take the rank of the younger.
Should serve - Shall be subject to; shall not have the authority and priority, but should be inferior to. The passage in Genesis Genesis 25:23 shows that this had reference particularly to the posterity of Esau, and not to him as an individual. The sense is, that the descendants of Esau, who were Edomites, should be inferior to, and subject to the descendants of Jacob. Jacob was to have the priority; the promised land; the promises; and the honor of being regarded as the chosen of God. There was reference here, therefore, to the whole train of temporal and spiritual blessings which were to be connected with the two races of people. If it be asked how this bears on the argument of the apostle, we may reply,
(1) That it settles "the principle" that God might make a distinction among people, in the same nation, and the same family, without reference to their works or character.
(2) that he might confer his blessings on such as he pleased.
(3) if this is done in regard to nations, it may be in regard to individuals. The principle is the same, and the justice the same. If it be supposed to be unjust in God to make such a distinction in regard to individuals, it is surely not less so to make a distinction in nations. The fact that numbers are thus favored, does not make it the more proper, or remove any difficulty.
(4) if this distinction may be made in regard to temporal things, why not in regard to spiritual things? The principle must still be the same. If unjust in one case, it would be in the other. The fact that it is done in one case proves also that it will be in the other; for the same great principle will run through all the dealings of the divine government. And as people do not and cannot complain that God makes a distinction among them in regard to talents, health, beauty, prosperity, and rank, neither can they complain if he acts also as a sovereign in the distribution of his spiritual favors. They, therefore, who regard this as referring only to temporal and national privileges, gain no relief in respect to the real difficulty in the case, for the unanswerable question would still be asked, why has not God made all people equal in everything? Why has he made any distinction among people? The only reply to all such inquiries is, "Even so, Father, for so it seemeth good in thy sight;" Matthew 11:26.

The elder shall serve the younger - These words, with those of Malachi, Jacob have I loved, and Esau have I hated, are cited by the apostle to prove, according to their typical signification, that the purpose of God, according to election, does and will stand, not of works, but of him that calleth; that is, that the purpose of God, which is the ground of that election which he makes among men, unto the honor of being Abraham's seed, might appear to remain unchangeable in him; and to be even the same which he had declared unto Abraham. That these words are used in a national and not in a personal sense, is evident from this: that, taken in the latter sense they are not true, for Jacob never did exercise any power over Esau, nor was Esau ever subject to him. Jacob, on the contrary, was rather subject to Esau, and was sorely afraid of him; and, first, by his messengers, and afterwards personally, acknowledged his brother to be his lord, and himself to be his servant; see Genesis 32:4; Genesis 33:8, Genesis 33:13. And hence it appears that neither Esau nor Jacob, nor even their posterities, are brought here by the apostle as instances of any personal reprobation from eternity: for, it is very certain that very many, if not the far greatest part, of Jacob's posterity were wicked, and rejected by God; and it is not less certain that some of Esau's posterity were partakers of the faith of their father Abraham.
From these premises the true sense of the words immediately following, Jacob have I loved, and Esau have I hated, Malachi 1:2, Malachi 1:3, fully appears; that is, that what he had already cited from Moses concerning the two nations, styled by the names of their respective heads, Jacob and Esau, was but the same in substance with what was spoken many years after by the Prophet Malachi. The unthankful Jews had, in Malachi's time, either in words or in their heart, expostulated with God, and demanded of him wherein he had loved them? I have loved you, saith the Lord: yet ye say, Wherein hast thou loved us? Malachi 1:2-5. To this the Lord answers: Was not Esau Jacob's brother? Yet I loved Jacob and hated Esau, and laid his mountains and his heritage waste for the dragons of the wilderness. Whereas Edom saith, We are impoverished, but we will return and build the desolate places; thus saith the Lord of hosts, They shall build, but I will throw down; and they shall call them, The border of wickedness, and, The people against whom the Lord hath indignation for ever. And your eyes shall see, and ye shall say, The Lord will be magnified from the border of Israel.
1. It incontestably appears from these passages that the prophet does not speak at all of the person of Jacob or Esau, but of their respective posterities. For it was not Esau in person that said, We are impoverished; neither were his mountains nor heritage laid waste. Now, if the prophet speaks neither of the person of the one nor of the person of the other, but of their posterity only, then it is evident that the apostle speaks of them in the same way.
2. If neither the prophet nor the apostle speaks of the persons of Jacob or Esau, but of their posterity, then it is evident that neither the love of God to Jacob, nor the hatred of God to Esau, were such, according to which the eternal states of men, either in happiness or misery, are to be determined; nor is there here any Scriptural or rational ground for the decree of unconditional personal election and reprobation, which, comparatively, modern times have endeavored to build on these scriptures. For,
1. It is here proved that Esau is not mentioned under any personal consideration, but only as the head of his posterity.
2. The testimony of Scripture amply proves that all Esau's posterity were not, even in this sense, reprobated; nor all Jacob's posterity elected.
3. Neither does that service, or subjugation to Jacob, which the Divine oracle imposed on Esau, import any such reprobation as some contend for; as the servant may be elected, while the master himself is in a state of reprobation.
4. Were it even granted that servitude did import such a reprobation, yet it is certain that Esau, in person, never did serve Jacob.
5. Nor does the hatred of God against Esau import any such reprobation of the person of Esau, because it is demonstrable that it related, not to Esau personally, but to his posterity.
6. The scope of the apostle's reasoning is to show that God is the sovereign of his own ways, has a right to dispense his blessings as he chooses, and to give salvation to mankind, not in the ways of their devising, but in that way that is most suitable to his infinite wisdom and goodness.
Therefore,
1. He chose the Jewish people from all others, and revealed himself to them. Thus they were the elect, and all the nations of mankind reprobate.
2. When the fullness of the time came he revealed himself also to the Gentiles, who gladly received the Gospel: and the Jews rejecting it, were cast off. Thus the elect became reprobate, and the reprobate, elect.
3. He published to all mankind that the pardon of sin could and should be obtained Only by faith in his Son Jesus, and not by any obedience to any law. And the Jews, the descendants of Jacob, who rejected this way of salvation, became precisely like the Edomites, the descendants of Esau; they builded, but God pulled down; their mountains and heritage are Now laid waste for the dragons of the wilderness; and they properly may now be called the border of wickedness, a people against whom the Lord hath indignation for ever: they have rejected the Lord that bought them, and so have brought upon themselves swift destruction.
7. That no personal, absolute, eternal reprobation of Esau can have been intended, we learn from this; that he was most amply reconciled to his brother, who had so deeply wronged and offended him, by depriving him of his birthright and his blessing: and his having forgiven his brother his trespasses, was no mean proof that God had forgiven him. See our Lord's words, Matthew 6:14. Therefore there can be assigned no competent ground of his damnation, much less of his personal reprobation from all eternity.
8. And were such a personal reprobation intended, is it not shocking to suppose that the God of endless mercy, in whose sight his pious parents had found favor, should inform them, even before their child was born, that he had absolutely consigned him, by an irrevocable decree to eternal damnation? A message of such horrid import coming immediately from the mouth of God, to a tender, weak, and delicate woman, whose hour of travail with two children was just at hand, could not have failed to produce abortion, and destroy her life. But the parents perfectly understood their God, and saw no decree of reprobation in his message; two manner of nations are in thy womb - and the elder shall serve the younger.
9. There is no reason, worthy the most wise and gracious God, why he should make known to the world such a thing concerning Esau, who was yet unborn, that he had reprobated him from all eternity. Such a revelation could be of no spiritual advantage or edification to mankind, but rather of a malignant influence, as directly occasioning men to judge hardly of their Maker, and to conceive of him as no faithful Creator; as having no care, no love, no bowels of compassion towards the workmanship of his own hands. See Goodwin's Exposition: and see my notes on Genesis 27 (note).

(9) It was said unto her, The elder shall serve the younger.
(9) He proves the casting away of Esau in that he was made servant to his brother: and proves the choosing of Jacob in that he was made lord of his brother, although his brother was the first begotten. And in order that no man might take what God had said, and refer it to external things, the apostle shows out of Malachi, who is a good interpreter of Moses, that the servitude of Esau was joined with the hatred of God, and the lordship of Jacob with the love of God.

It was said unto her,.... To Rebecca, Genesis 25:23,
the elder shall serve the younger, or "the greater shall serve the lesser", an Hebrew way of speaking; so Japheth is called "the great", or, as we render it, "the elder", Genesis 10:21; and the evil imagination is said (i) to be "greater", that is, elder than the good, thirteen years; See Gill on Luke 22:26; The sense is, Esau shall be a servant to Jacob; which is to be understood, not of temporal servitude; for in this sense he never was a servant to him; so far from it, that as soon as Jacob had got the birthright and blessing, he was obliged to flee from the face and fury of Esau; and upon his return after many years, he sent messengers to Esau in a very submissive manner, charging them after this manner, "thus shall ye shall say to my lord Esau, thy servant Jacob saith thus", &c. Genesis 32:4, and when he found that his brother was coming to meet him, which threw him into a panic fear, lest he should "smite him, and the mother with the children", Genesis 32:11, he prepares presents for him; and when he came to him, bowed himself seven times, and his wives and children bowed likewise; and the language in which he addressed his brother Esau, all the while they were together, was that of "my lord": now if this oracle was to be understood of outward temporal servitude, it is strange it should have no appearance, nor any shadow of an accomplishment in the persons of Jacob and Esau, supposing it was to have one in their posterity; and indeed the completion of it, in this sense, is not very evident in their offspring. It is certain, there was a long train of dukes and kings in Esau's family, before there was any king in Israel; the posterity of Esau were in lordly grandeur and splendour, when the children of Israel were grievously oppressed with hard bondage in Egypt. The single instance usually referred to, when the Edomites became tributaries to David, was near a thousand years after the giving out of this oracle; and this show of servitude did not last long, for in Joram's time they revolted, and so continued; and it is evident, that at the time of the Babylonish captivity, the children of Edom were prosperous and triumphant, and said concerning Jerusalem, "Raze it, raze it, even to the foundation thereof", Psalm 137:7, this servitude therefore is to be understood in a spiritual sense, of Esau's exclusion from the favour of God, and blessings of grace, signified by his being rejected from inheriting the blessing, which was given to Jacob; and it appeared that he was not a son, but a servant, by his departure, and pitching his dwelling elsewhere; which showed he had no interest in spiritual adoption, no right to the covenant of grace, nor was he an heir of heaven, all which were peculiar to Jacob: Esau was a servant of sin, under the dominion of it, and in bondage to it; whilst Jacob was the Lord's freeman, and, as a prince, had power with God and with men, and prevailed: Esau was serviceable to Jacob, both in things temporal and spiritual; as reprobates are to the elect, for all things are for their sakes, and work together for their good; Jacob's being obliged to flee from his brother, was for his good; by this means he got him a suitable wife, and large substance: his brother's meeting him on his return, which gave him so much pain and uneasiness, issued in his spiritual good; this sent him to the throne of grace, to humble himself before God, acknowledge his mercies, and his dependence on him, to implore his help, and plead his promises; and thus the oracle was verified in the persons of Jacob and Esau.
(i) Midrash Kohelet, fol. 80. 1.

The elder - Esau. Shall serve the younger - Not in person, for he never did; but in his posterity. Accordingly the Edomites were often brought into subjection by the Israelites. Genesis 25:23.
