Genesis 30 · a question people ask
Why did Rachel and Leah give their servants to Jacob?
Rachel says why: "that she may bear on my knees, and I also may obtain children by her" (30:3). Her Hebrew repeats what Sarai said when she gave Hagar to Abram: the same verb, ibbaneh, with "by her", mimmennah, which the WEB translates the same way both times: "It may be that I will obtain children by her" (16:2). Leah gives Zilpah "when Leah saw that she had finished bearing" (30:9). The sayings at each birth show the rivalry: "I have wrestled with my sister with mighty wrestlings, and have prevailed" (30:8).
