Genesis 30:2
And Jacob’s anger was kindled against Rachel: and he said, Am I in God’s stead, who hath withheld from thee the fruit of the womb? And Jacob’s anger was kindled against Rachel: and he said, Am I in God’s stead, who hath withheld from thee the fruit of the womb?
The verse belongs to the account of the sons born to Jacob while he lived in the land of the children of the East, where he met Laban and served him fourteen years for his two daughters. The surrounding chapter describes Jacob's marriages to Leah and Rachel and his sojourn with Laban, where he who had deceived his father was himself deceived, yet the narrative shows God's care for Jacob despite his selfishness and unfaithfulness. The verse falls within the record of Jacob's troubled and unsatisfactory experiences, in which his selfish dealings brought suffering and his own overreaching was met with overreaching as God's providence brought retribution in time.
The chapter is part of the larger story of Abraham's family and Jacob's development toward his victory when he was called Israel, meaning prevailer with God. In the verse Jacob answers Rachel's distress over having no children by denying that he stands in God's place, affirming that it is God who has withheld the fruit of the womb and thereby recognizing God's power over conception and childbirth. The passage belongs to the patriarchal record of plain violation of the institution of marriage through Jacob's plural marriages.
Such violation does not destroy or lessen the sacred character of marriage. Marriage was made for humanity before the fall, so its sanctity is not derived from the Decalogue, and the seventh commandment guards its sacredness. As the seventh commandment guards marriage, the fourth commandment guards the Sabbath, so even a proven Sabbath violation in the patriarchal age would no more destroy the sacred character of the Sabbath than the violations in this passage destroy that of marriage. The chapter displays the very great unhappiness that polygamy brought into Jacob's family, which together with the families of Abraham and David proves that polygamy was always evil and wrong and contrary to the original order in Eden, though tolerated because of hardness of heart.
