What Does “I Will Be Built From/Through Her” in Genesis 16:2 and Genesis 30:3 Mean?

In Genesis 16:1, we are reminded that Sarah has not been able to become pregnant with Abraham. In v. 2, she makes the following proposal: Behold, the Lord has prevented me from bearing. Have intercourse with my maidservant; perhaps I will be built from/through her. The expression ‘ibbaneh mimmenna is an unusual one; the same expression, coupled with another even more unusual phrase, appears in Genesis 30:3 when Rachel gives her maidservant Bilhah to Jacob. These are the only two places in the Hebrew Bible where the expression appears. Since one woman cannot literally “build” another, the phrase must have an idiomatic meaning. This article reviews the traditional Jewish commentators’ understanding of a woman’s “being built,” and the accepted modern explanation of how she might be built “from/through her maidservant” — which, it argues, is seriously flawed.

The Meaning of “I Will Be Built”

Rashi, Ibn Ezra, Ramban, and Sforno all assume that “I will be built” idiomatically means “I will become able to get pregnant myself.” Ibn Ezra proposes that ’ibbaneh derives from the noun ben (son), since a child is a sort of “building” erected on the “foundation” of the parents. Modern commentators, comparing biblical Hebrew with Akkadian, have found that the root b.n.h. in that language refers not only to erecting physical structures but also to having children; Hermann Gunkel and E.A. Speiser both note this “denominative” usage, with Speiser translating the phrase in both Genesis 16:2 and 30:3 as “maybe I shall reproduce through her.” The evidence from Akkadian thus supports the idea that “build” in these verses refers to procreation, whether or not the verb is technically a denominative form of ben.

A Parallel Biblical Verse

The biblical idiom “building a house” (as in I Samuel 2:35 and Ruth 4:11) means building a family or dynasty, but the verb there is active and the object is a house, not a woman. One verse, however, uses the verb almost exactly as in our verses: Jeremiah 31:4, ‘od evnech venivnet betulat yisra’el (“Again will I build you, and you shall be built, O Virgin Israel”). Radak explains this as a metaphor for the exiles’ return; Jack Lundbom sees it as a wider metaphor for increased population, prosperity, and community life. Either way, the “being built” rests upon an increased population — the prophet’s use of the verb in both stems is intended to evoke high fertility, supporting the reading of “I will be built” in Genesis as “I will become fertile and bear a child.”

The Ancient Near Eastern Evidence

Rashi and Sforno alone among the traditional commentators suggest how a wife might be built “from/through her maidservant,” offering moral or quasi-physical explanations in which the husband’s or wife’s “priming” through success with the maidservant leads to the wife’s own pregnancy. Modern commentators instead turn to ancient Near Eastern legal texts: the Lipit-Ishtar law code, an Old Assyrian marriage contract, the Code of Hammurabi, and two Nuzi adoption agreements. These documents are chiefly concerned with securing an heir and with the legal status of a maidservant who has borne a child and then “claims equality” with her mistress — not, this article argues, with rendering the wife herself fertile.

Gunkel proposes that Sarah and Rachel hoped to obtain children through a form of surrogacy, in which the maidservant “stands in” for the wife, an idea he connects to the “giving birth on my knees” language of Genesis 30:3 as a symbolic adoption ceremony. Speiser finds support for this in a Hurrian adoption text from Nuzi in which a childless wife is said to have “authority over the offspring” of a concubine given to her husband, arguing that this authority is the “exact bearing” of the term ’ibbaneh. However, “authority over the offspring” need not mean legal motherhood; it may simply mean the right to make decisions about the child, a provision that may have existed to protect the wife’s status in a household where she herself had been given to the husband as part of an inheritance arrangement.

Assessing the Evidence

These documents are few in number and it is not valid to infer that they reflect binding customs that the patriarchs and matriarchs were themselves subject to; at most, they show that similar issues and options were current in the ancient Near East. Of the three possible meanings for the phrase — that the wife’s own fertility is boosted; that she gains motherhood status without the child being biologically hers; or that she becomes a mother through surrogacy/adoption — the Jeremiah 31:4 parallel, where no surrogacy is remotely possible, argues strongly for the first.

Furthermore, the biblical narrative itself resists the surrogacy reading. In Genesis 16, Hagar is insolent toward Sarah before she even gives birth, and Sarah’s status, if anything, deteriorates; Sarah physically abuses the pregnant Hagar, behavior difficult to reconcile with a wife who considers herself the unborn child’s true mother. In Genesis 21, Sarah does not relate to Ishmael as her own and appeals to Abraham to expel “that slave-woman and her son” — not “my son” — so that Ishmael will not be an heir alongside Isaac. In Genesis 30, the phrase “I too will be built” plausibly anticipates Rachel’s own subsequent pregnancy rather than describing a legal fiction attached to Bilhah’s children.

Sarah’s Apparent Age

A further difficulty is that Sarah, by the chronology given in Genesis 17 (ten years younger than Abraham, who was seventy-five at the migration to Canaan and eighty-five ten years later when Sarah makes her proposal), would already be around seventy-five and presumably post-menopausal at the time of Genesis 16 — a problem the traditional commentators do not address, but which the Documentary Hypothesis might resolve by attributing the ages to a later Priestly source layered onto an earlier narrative that assumed Sarah was still of childbearing age.

Conclusion

The evidence favors the traditional reading that “I will be built” means “I personally will become able to bear a child,” and that the modern surrogacy/adoption reading of “from/through my maidservant” fits neither the ancient Near Eastern documents nor the biblical text itself. A possible mechanism, building on Sforno’s suggestion that Abraham’s success with Hagar somehow “primed” Sarah, is that the phrase originated in a belief resembling sympathetic magic — that a husband’s successful impregnation of his wife’s maidservant was believed to transfer fertility to the wife herself. The biblical text as we have it, however, gives no indication that it understands the events in Genesis 16 or 30 as magical; in Sarah’s case, the text is explicit that her eventual pregnancy is a result of the Lord’s promise and will, not of any procedure involving Hagar.
