Prohibition of adultery

The Prohibition of adultery is one of the commandments delivered at Sinai, where it appears alongside prohibitions of murder, theft, and false testimony. Its concise form belongs to a wider body of law and narrative concerned with marriage, sexual conduct, household authority, and the consequences of relationships for family life and inheritance.

The Commandment and Its Legal Setting

At Sinai, the prohibition is given to the assembled people as part of a covenantal code. The surrounding commandments also forbid other gods and images, require Sabbath rest, and protect parents, neighbors, and property. Adultery is thus placed within a broad account of obligations governing both worship and social life.

The legal material elsewhere distinguishes several sexual situations rather than reducing them to one general rule. Among them are regulations concerning marriage, divorce, and forbidden relationships, as well as curses pronounced for specific sexual violations at the covenant ceremony on Mount Ebal. These passages establish that sexual conduct is treated as a matter of communal and covenantal concern, although they do not supply a single, detailed definition of adultery in the commandment itself.

Households, Marriage, and Reproductive Agency

The narratives depict households in which marriage and reproduction are bound up with lineage and inheritance. When Sarah has no children, she gives Hagar, her Egyptian handmaid, to Abraham as a wife; after Hagar conceives, conflict develops between the women, and Sarah deals harshly with her. Hagar flees, but the Angel of the LORD finds her in the wilderness and promises that her descendants will be numerous. She returns and gives birth to Ishmael.

The pressure of succession recurs after Isaac is born. At Sarah’s demand, Abraham sends Hagar and Ishmael away, though God promises to make Ishmael a nation as well. The episode shows how decisions made within a marriage and household could determine a woman’s mobility and a child’s place in the family, while the narrative also records divine protection for the expelled mother and son.

Jacob’s household likewise links marriage, fertility, and rivalry. Laban substitutes Leah for Rachel on Jacob’s wedding night, and Jacob then serves seven additional years for Rachel. Leah bears sons while Rachel is barren; Rachel gives Jacob her handmaid Bilhah, and Leah later gives him Zilpah. The account traces the birth of Jacob’s sons through competing household arrangements, making the household’s structure and the women’s reproductive roles central to the growth of the family.

Sexual Conduct, Power, and Narrative Judgment

The Dinah episode presents a different collision of sexual conduct and household authority. Shechem violates Dinah and then seeks to marry her; his father Hamor proposes intermarriage and shared settlement with Jacob’s family. Jacob’s sons respond deceitfully, making circumcision of every male in the city a condition of agreement. The episode frames the proposed marriage within a conflict over injury, family power, and the terms of joining communities.

The story of Judah and Tamar turns on a withheld marriage obligation. After Judah’s sons Er and Onan die, Judah tells Tamar to remain a widow until his younger son Shelah grows up, but does not give her to Shelah when he is grown. Tamar later obtains Judah’s signet, cord, and staff as pledges; when her pregnancy is disclosed, Judah orders punishment, but she presents the pledges that identify him as the father. The narrative exposes the unequal authority within the household and the consequences of Judah’s failure to fulfill his promise.

Covenant, Judgment, and Communal Consequences

At Mount Ebal, the Levites pronounce curses for particular violations, and the people answer each with Amen. These include sexual offenses within prohibited family relationships, alongside wrongdoing such as idolatry, dishonoring parents, moving a boundary marker, and perverting justice for the stranger, the fatherless, and the widow. The ritual turns legal declarations into public responses and places sexual conduct among acts for which the covenant community accepts accountability.

The wider covenant address connects obedience with blessing and disobedience with death, evil, and loss of the land. In that framework, the prohibition of adultery is not merely a private rule: it belongs to a system that binds household conduct to fidelity toward the LORD and to Israel’s life as a people. The narratives, meanwhile, show that marital and sexual arrangements have concrete consequences for women’s status, children’s inheritance, family conflict, and the formation of Israel’s ancestral households.
