Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary
The Right of the first-born. - Whilst the previous law was intended to protect the slave taken in war against the caprice of her Israelitish master, the law which follows is directed against the abuse of paternal authority in favour of a favourite wife. If a man had two wives, of whom one was beloved and the other hated, - as was the case, for example, with Jacob, - and had sons by both his wives, but the first-born by the wife he hated, he was not, when dividing his property as their inheritance, to make the son of the wife he loved the first-born, i.e., was not to give him the inheritance of the first-born, but was to treat the son of the hated wife, who was really the first-born son, as such, and to give him a double share of all his possession. בּכּר, to make or institute as first-born. וגו בּן על־פּני, over (by) the face of, i.e., opposite to the first-born son of the hated, when he was present; in other words, "during his lifetime" (cf. Gen 11:28). יכּיר, to regard as that which he is, the rightful first-born. The inheritance of the first-born consisted in "a mouth of two" (i.e., a mouthful, portion, share of two) of all that was by him, all that he possessed. Consequently the first-born inherited twice as much as nay of the other sons. "Beginning of his strength" (as in Gen 49:3). This right of primogeniture did not originate with Moses, but was simply secured by him against arbitrary invasion. It was founded, no doubt, upon hereditary tradition; just as we find in many other nations, that certain privileges are secured to the first-born sons above those born afterwards.
Jamieson-Fausset-Brown Bible Commentary
If a man have two wives, one beloved, and another hated--In the original and all other translations, the words are rendered "have had," referring to events that have already taken place; and that the "had" has, by some mistake, been omitted in our version, seems highly probable from the other verbs being in the past tense--"hers that was hated," not "hers that is hated"; evidently intimating that she (the first wife) was dead at the time referred to. Moses, therefore, does not here legislate upon the case of a man who has two wives at the same time, but on that of a man who has married twice in succession, the second wife after the decease of the first; and there was an obvious necessity for legislation in these circumstances; for the first wife, who was hated, was dead, and the second wife, the favorite, was alive; and with the feelings of a stepmother, she would urge her husband to make her own son the heir. This case has no bearing upon polygamy, which there is no evidence that the Mosaic code legalized.
John Gill Bible Commentary
If a man have two wives,.... Which is supposed, but not approved of, though permitted because of the hardness of men's hearts; for it was not so from the beginning, when only one man and one woman were created, and joined together in marriage; but as it was connived at, and become customary, a law is made to prevent confusion, and preserve order in families:
one beloved and another hated; or less loved, yet continued his wife, and not divorced. Aben Ezra observes, this follows upon the former, because it is there said, that though first he had a desire to her (the captive beautiful woman), yet afterwards had no delight in her:
and they have borne him children both, the beloved and the hated; as Rachel and Leah did to Jacob, who were, the one very much beloved by him, and the other less:
and if the firstborn son be hers that was hated; or not so much beloved as the other, as was the case in the above instance.
Matthew Henry Bible Commentary
This law restrains men from disinheriting their eldest sons out of mere caprice, and without just provocation.
I. The case here put (Deu 21:15) is very instructive. 1. It shows the great mischief of having more wives than one, which the law of Moses did not restrain, probably in hopes that men's own experience of the great inconvenience of it in families would at last put an end to it and make them a law to themselves. Observe the supposition here: If a man have two wives, it is a thousand to one but one of them is beloved and the other hated (that is, manifestly loved less) as Leah was by Jacob, and the effect of this cannot but be strifes and jealousies, envy, confusion, and every evil work, which could not but create a constant uneasiness and vexation to the husband, and involve him both in sin and trouble. Those do much better consult their own ease and satisfaction who adhere to God's law than those who indulge their own lusts. 2. It shows how Providence commonly sides with the weakest, and gives more abundant honour to that part which lacked; for the first-born son is here supposed to be hers that was hated; it was so in Jacob's family: because the Lord saw that Leah was hated, Gen 29:31. The great householder wisely gives to each his dividend of comfort; if one had the honour to be the beloved wife, it often proved that the other had the honour to be the mother of the first-born.
II. The law in this case is still binding on parents; they must give their children their right without partiality. In the case supposed, the eldest son, though the son of the less-beloved wife, must have his birthright privilege, which was a double portion of the father's estate, because he was the beginning of his strength that is, in him his family began to be strengthened and his quiver began to be filled with the arrows of a mighty man (Psa 127:4), and therefore the right of the first-born is his, Deu 21:16, Deu 21:17. Jacob had indeed deprived Reuben of his birthright, and given it to Joseph, but it was because Reuben had forfeited the birthright by his incest, not because he was the son of the hated; now, lest that which Jacob did justly should be drawn into a precedent for others to do the same thing unjustly, it is here provided that when the father makes his will, or otherwise settled his estate, the child shall not fare the worse for the mother's unhappiness in having less of her husband's love, for that was not the child's fault. Note, (1.) Parents ought to make no other difference in dispensing their affections among their children than what they see plainly God makes in dispensing his grace among them. (2.) Since it is the providence of God that makes heirs, the disposal of providence in that matter must be acquiesced in and not opposed. No son should be abandoned by his father till he manifestly appear to be abandoned of God, which is hard to say of any while there is life.
Tyndale Open Study Notes
21:15-17 The law required that a firstborn son receive the greater share of his father’s inheritance (see 21:15-16; 2 Kgs 2:9). The custom of giving the firstborn son a double portion is first recorded here but was implied in earlier practice (see Gen 25:31-34; 27:1-4; 48:8-22). • son of his father’s virility: The eldest male child carried this distinction because he proved that the man was capable of siring children, and a boy in particular.
