What does Genesis 30:23 mean?

This chapter opened with Rachel crying out in despair against Jacob, "Give me children, or I shall die!" (Genesis 30:1). This was unfair, first of all, since Jacob had already fathered four children with his other wife, Rachel's sister Leah (Genesis 29:31–35). Jacob corrected her: God is the one who gives children. But Rachel, just like the culture of her era, would have viewed infertility as something shameful—a barren womb would have made Rachel feel like a lesser woman. This, in no small part, explains her zeal in pursuing a "birth war" against her own sister (Genesis 30:8), resulting in a total of ten sons born to Jacob by this point in history.

The previous verse told us that God "remembered" Rachel. This does not mean, of course, that she had slipped His mind for a few years. It means that He thought of her with favor. He showed her mercy. He responded to her prayers by making her able to become pregnant with Jacob. So, she conceives and has a son, giving credit to God for taking that cultural shame and reproach away. She acknowledges that God is the giver of this good gift.
