Genesis 29:31 Meaning and Commentary

Genesis 29:31

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 30:22-24 ) .

31 And when the Lord God saw that Lea was hated, he opened her womb; but Rachel was barren.
32 And Lea conceived and bore a son to Jacob; and she called his name, Ruben; saying, Because the Lord has looked on my humiliation, and has given me a son, now then my husband will love me.
33 And she conceived again, and bore a second son to Jacob; and she said, Because the Lord has heard that I am hated, he has given to me this one also; and she called his name, Simeon.
