Genesis 30:1

“And when Rachel saw that she bare Jacob no children, etc.] In the space of three or four years after marriage, and when her sister Leah had had four sons: Rachel envied her sister; the honour she had of bearing children, and the pleasure in nursing and bringing them up, when she lay under the reproach of barrenness: or, “she emulated her sisters” f1487; was desirous of having children even as she, which she might do, and yet not be guilty of sin, and much less of envy, which is a very heinous sin: and said unto Jacob, give me children, or else I die; Rachel could never be so weak as to imagine that it was in the power of Jacob to give her children at his pleasure, or of a barren woman to…”

“DOMESTIC JEALOUSIES. (Gen. 30:1-24) Rachel envied her sister--The maternal relation confers a high degree of honor in the East, and the want of that status is felt as a stigma and deplored as a grievous calamity. Give me children, or else I die--either be reckoned as good as dead, or pine away from vexation. The intense anxiety of Hebrew women for children arose from the hope of giving birth to the promised seed. Rachel's conduct was sinful and contrasts unfavorably with that of Rebekah (compare Gen 25:22) and of Hannah (Sa1 1:11).”

“30:1-8 Rachel’s naming of sons through Bilhah does not reflect faith as Leah’s namings had. Rachel felt wronged over the marriage and her barrenness. The names of Bilhah’s sons reflect Rachel’s bitter struggle with her sister and her feeling of some victory. 30:1-2 In that culture, it was like death for a woman not to have children (cp. 1 Sam 1); only God could open Rachel’s womb.”
