And when the Lord saw. Moses here shows that Jacob's extravagant love was corrected by the Lord; as the affections of the faithful, when they become inordinate, are wont to be tamed by the rod. Rachel is loved, not without wrong to her sister, to whom due honor is not given. The Lord, therefore, interposes as her vindicator, and, by a suitable remedy, turns the mind of Jacob into that direction, to which it had been most averse. This passage teaches us, that offspring is a special gift of God; since the power of rendering one fertile, and of cursing the womb of the other with barrenness, is expressly ascribed to him. We must observe further, that the bringing forth of offspring tends to conciliate husbands to their wives. Whence also the ancients have called children by the name of pledges; because they avail, in no slight degree, to increase and to cherish mutual love. When Moses asserts that Leah was hated, his meaning is, that she was not loved so much as she ought to have been. For she was not intolerable to Jacob, neither did he pursue her with hatred; but Moses, by the use of this word, amplifies his fault, in not having discharged the duty of a husband, and in not having treated her who was his first wife with adequate kindness and honor. It is of importance carefully to notice this, because many think they fulfill their duty if they do not break out into mortal hatred. But we see that the Holy Spirit pronounces those as hated who are not sufficiently loved; and we know, that men were created for this end, that they should love one another. Therefore, none will be counted guiltless of the crime of hatred before God, but he who embraces his neighbors with love. For not only will a secret displeasure be accounted as hatred, but even that neglect of brethren, and that cold charity which ever reigns in the world. But in proportion as any one is more closely connected with another, must be the endeavor to adhere to each other in a more sacred bond of affection. Moreover, with respect to married persons, though they may not openly disagree, yet if they are cold in their affection towards each other, this disgust is not far removed from hatred.

The Lord saw that Leah was hated - From this and the preceding verse we get the genuine meaning of the word שנא sane, to hate, in certain disputed places in the Scriptures. The word simply signifies a less degree of love; so it is said, Genesis 29:30 : "Jacob loved Rachel more than Leah," i.e., he loved Leah less than Rachel; and this is called hating in Genesis 29:31 : When the Lord saw that Leah was hated - that she had less affection shown to her than was her due, as one of the legitimate wives of Jacob, he opened her womb - he blessed her with children. Now the frequent intercourse of Jacob with Leah (see the following verses) sufficiently proves that he did not hate her in the sense in which this term is used among us; but he felt and showed less affection for her than for her sister. So Jacob have I loved, but Esau have I hated, simply means, I have shown a greater degree of affection for Jacob and his posterity than I have done for Esau and his descendants, by giving the former a better earthly portion than I have given to the latter, and by choosing the family of Jacob to be the progenitors of the Messiah. But not one word of all this relates to the eternal states of either of the two nations. Those who endeavor to support certain peculiarities of their creed by such scriptures as these, do greatly err, not knowing the Scripture, and not properly considering either the sovereignty or the mercy of God.

And when the LORD saw that Leah [was] hated, he (k) opened her womb: but Rachel [was] barren.
(k) This declares that often they who are despised by men are favoured by God.

And when the Lord saw that Leah was hated,.... Not properly and simply hated by Jacob, as appears by his doing the duty of an husband to her, but comparatively; she was less loved than Rachel: and there are many things to be said for it; she was not beautiful as Rachel was; she was not Jacob's choice, as she was but imposed upon him through deceit, and he was forced to marry her, or he could not have Rachel his beloved wife: but the Lord had pity on her, and that she might have a share in her husband's affections:
he opened her womb; or gave her conception; as Onkelos paraphrases it:
but Rachel was barren; bare no children as yet, and for many years after, Genesis 30:22.

The names Leah gave her children, expressed her respect and regard, both to God and to her husband. Reuben, or See a son, with this thought, Now will my husband love me; Levi, or joined, expecting, Now will my husband be joined unto me. Mutual affection is both the duty and comfort of the married relation; and yoke-fellows should study to recommend themselves to each other, 1-Corinthians 7:33, 1-Corinthians 7:34. She thankfully acknowledges the kind providence of God in hearing her. Whatever supports and comforts us under afflictions, or tends to our deliverance from them, God must be owned in it. Her fourth son she called Judah, or praise, saying, Now will I praise the Lord. This was he, of whom, as concerning the flesh, Christ came. Whatever is the matter of our rejoicing, ought to be the matter of our thanksgiving. Fresh favours should quicken us to praise God for former favours; Now will I praise the Lord more and better than I have done. All our praises must centre in Christ, both as the matter of them, and as the Mediator of them. He descended after the flesh from him whose name was "Praise," and He is our praise. Is Christ formed in my heart? Now will I praise the Lord.

Leah . . . hated--that is, not loved so much as she ought to have been. Her becoming a mother ensured her rising in the estimation both of her husband and of society.

Leah's First Sons. - Jacob's sinful weakness showed itself even after his marriage, in the fact that he loved Rachel more than Leah; and the chastisement of God, in the fact that the hated wife was blessed with children, whilst Rachel for a long time remained unfruitful. By this it was made apparent once more, that the origin of Israel was to be a work not of nature, but of grace. Leah had four sons in rapid succession, and gave them names which indicated her state of mind: (1) Reuben, "see, a son!" because she regarded his birth as a pledge that Jehovah had graciously looked upon her misery, for now her husband would love her; (2) Simeon, i.e., "hearing," for Jehovah had heard, i.e., observed that she was hated; (3) Levi, i.e., attachment, for she hoped that this time, at least, after she had born three sons, her husband would become attached to her, i.e., show her some affection; (4) Judah (יהוּדה, verbal, of the fut. hoph. of ידה), i.e., praise, not merely the praised one, but the one for whom Jehovah is praised. After this fourth birth there was a pause (Genesis 29:31), that she might not be unduly lifted up by her good fortune, or attribute to the fruitfulness of her own womb what the faithfulness of Jehovah, the covenant God had bestowed upon her.

When the Lord saw that Leah was hated - That is, loved less than Rachel, in which sense it is required that we hate father and mother, in comparison with Christ, Luke 14:26, then the Lord granted her a child, which was a rebuke to Jacob for making so great a difference between those he was equally related to; a check to Rachel, who, perhaps insulted over her sister upon that account; and a comfort to Leah, that she might not be overwhelmed with the contempt put upon her.
