Was Abram's union with Hagar adultery or bigamy? Study Genesis 16 with context, apologetic analysis, and cross-references.
Dr. Lucas D. Shallua Commentary · GENESIS 16 — HAGAR AND ISHMAEL
Neither, in its setting: slave-concubinage under the wife's authority was a recognized legal institution of the period (documented in Hammurabi's code and Nuzi contracts). Scripture evaluates the act not by modern categories but covenantally: it was a failure of faith in the promise's power and timing, and its fruit was conflict. The episode thereby teaches a permanent principle — what is legal can still be unbelief.
The command to return (16:9) is a word about facing rather than fleeing appointed difficulty, and it is followed immediately by promises — comfort sufficient for obedience. The chapter neither endorses Sarai's harshness nor commends flight as the default response to oppression; it commends the God who sees affliction and speaks into it (cf. 1 Peter 2:18–25 for the New Testament's shape of this obedience).
In this chapter the figure speaks with divine authority and Hagar's response is to name God as the one she has seen (16:13), leading many interpreters (ancient and modern) to identify the angel as a theophany — the LORD Himself appearing in the form of His messenger. Scripture elsewhere distinguishes the angel who bears God's name as though he were God (Exodus 3:2–6; 23:20–21; Judges 6:11–24). The New Testament's light confirms what the text's own claims suggest.
The chapter exposes the collision between ancient Near Eastern custom and covenant promise. Surrogacy by a slave-wife was a documented legal institution (the Code of Hammurabi and Nuzi tablets regulate it): the child born to the servant would count as the wife's. Sarah's proposal is, by the standards of the day, legally sophisticated — and spiritually fatal, as the chapter's chaos demonstrates. The lesson the New Testament draws (Galatians 4:21–31) is allegorical but pointed: the child of the slave versus the child of the promise, fleshly striving versus reception by faith, Sinai versus the Jerusalem above. The chapter also introduces Hagar — an Egyptian, a slave, a woman — as a full theological character: she sees God, names Him, receives promises for her son, and becomes the matriarch of a great nation (the Arabs, in the Bible's and history's memory). God's care for the outsider runs from Genesis to Jonah to the Great Commission.
The chapter's legal background — surrogate motherhood by a slave-wife, the wife's claim on the child, the mistress's disciplinary authority — is precisely regulated in second-millennium Near Eastern law codes (Hammurabi §§ 144–147; Nuzi contracts), anchoring the narrative in the patriarchal period's documented customs rather than in later Israelite law (which actually forbade giving a wife's maid to the husband, Leviticus 18:18 — evidence that the text records customs it does not legislate). The theological detail that the weakest character names God is the opposite of propaganda: no nation-building legend makes its founding hero's wife look cruel and a foreign slave look devout unless it is telling the truth as it happened.
This study preserves the hard questions, explanations, context, apologetic note, and references from Dr. Shallua's Commentary.
