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 .
