What does Genesis 30:2 mean?
Rachel, desperate for children and envious of her fertile sister, has demanded that Jacob give her children. Her statement implies that her barrenness is somehow his fault. This seems absurd, given that Leah has born four sons by Jacob. It also suggests Rachel did not have the same kind of relationship with the Lord that her sister did. Leah's actions in the prior chapter suggest that she is faithful to God, if somewhat resigned to the fact that Jacob will not love her the way he loves Rachel.For good reasons, Jacob is angry at Rachel's implied accusation. He corrects Rachel's assumption: God is the one who gives children, not husbands. Her complaint is with the Lord.
As did Jacob's grandmother Sarah (Genesis 16:1–4), Rachel will try to solve the problem her own way. This will start off something of a competition between the sisters, resulting in the births of many more sons to Jacob. Rachel will even name one of the resulting children to reflect her belief that this is a "struggle" between her and Leah (Genesis 30:8).
