Brother's Wife
The Institution of Levirate Marriage
In ancient Israel, a brother's wife occupied a distinctive legal and social position through the institution known as levirate marriage (from the Latin levir, meaning 'husband's brother'). When a married man died without producing a son, his surviving brother was obligated to marry the widow and raise up offspring in the deceased brother's name (Deuteronomy 25:5-6). The firstborn son of this union was legally regarded as the child of the deceased, inheriting his name and his property. This practice ensured the continuation of the family line, preserved the ancestral land within the clan, and provided for the widow's security.
The Law in Deuteronomy
The formal legislation regarding levirate marriage appears in Deuteronomy 25:5-10. If brothers lived together and one died without a son, the surviving brother was not to marry outside the family but was to take his brother's widow as his wife. The firstborn son would carry the dead brother's name 'so that his name may not be blotted out of Israel' (Deuteronomy 25:6).
However, the law also provided an escape clause. If the surviving brother refused to fulfill this duty, the widow could bring the matter before the elders at the city gate. If he still refused, the widow would publicly remove his sandal and spit in his face, declaring, 'So shall it be done to the man who does not build up his brother's house' (Deuteronomy 25:9). His family would thereafter be known in Israel as 'the house of him who had his sandal pulled off,' a lasting mark of social disgrace. This public shaming ceremony shows how seriously Israelite society took the obligation to preserve a brother's name and inheritance.
Tamar and Judah: A Pre-Mosaic Example
The story of Tamar and Judah in Genesis 38 provides the earliest biblical example of levirate custom, predating the formal legislation. When Judah's firstborn son Er died, Judah instructed his second son Onan to marry Tamar and 'raise up offspring for your brother' (Genesis 38:8). Onan, however, knowing the child would not be considered his own, deliberately prevented conception, an act that displeased God and resulted in his death (Genesis 38:9-10).
Judah then promised Tamar his youngest son Shelah but failed to follow through. Tamar eventually took matters into her own hands by disguising herself and conceiving twins by Judah himself. When the truth came out, Judah acknowledged, 'She is more righteous than I, since I did not give her to my son Shelah' (Genesis 38:26). Tamar's determined pursuit of her legal rights under levirate custom placed her in the genealogy of David and ultimately of Jesus Christ (Matthew 1:3).
Ruth and Boaz: Redemption Through Marriage
The book of Ruth presents the most fully developed narrative of levirate-related custom. After Naomi's sons died in Moab, her daughter-in-law Ruth returned with her to Bethlehem. Ruth's eventual marriage to Boaz, a kinsman of Naomi's deceased husband, combined the levirate principle with the institution of the kinsman-redeemer. Boaz acquired the right to marry Ruth only after the closer kinsman declined, unwilling to potentially complicate his own inheritance (Ruth 4:1-10).
The child born to Ruth and Boaz, Obed, was regarded as Naomi's grandson and restorer of her family line. The women of Bethlehem celebrated, saying, 'A son has been born to Naomi' (Ruth 4:17). Obed became the grandfather of King David, linking the levirate institution directly to the messianic line.
The Prohibition in Leviticus
Alongside the levirate obligation stood a general prohibition: 'You shall not uncover the nakedness of your brother's wife; it is your brother's nakedness' (Leviticus 18:16; 20:21). This created an apparent tension with the levirate law, which was resolved by understanding the prohibition as applying to situations where the brother was still living or had left children. The levirate duty was specifically triggered only by a childless death.
This distinction became historically significant when John the Baptist condemned Herod Antipas for marrying Herodias, his brother Philip's wife (Mark 6:18). Since Philip was still alive, the marriage violated the Levitical prohibition, and John's courageous rebuke ultimately cost him his life.
Jesus and the Sadducees' Question
The Sadducees, who denied the resurrection, posed a hypothetical scenario to Jesus involving levirate marriage: if a woman had been married to seven brothers in succession, whose wife would she be in the resurrection (Matthew 22:23-33; Mark 12:18-27; Luke 20:27-40)? Jesus answered that in the resurrection, people neither marry nor are given in marriage but are like the angels in heaven. He then demonstrated the reality of resurrection from the Torah itself, showing that the institution of levirate marriage, designed to preserve earthly family lines, would be transcended in the age to come.
Biblical Context
The brother's wife and levirate marriage appear in major narratives across Scripture: the story of Tamar and Judah (Genesis 38), the formal law in Deuteronomy 25:5-10, the prohibition in Leviticus 18:16 and 20:21, the story of Ruth and Boaz (Ruth 3-4), the inheritance law in Numbers 27:8, John the Baptist's condemnation of Herod (Mark 6:18), and the Sadducees' question to Jesus about the resurrection (Matthew 22:23-33).
Theological Significance
Levirate marriage reveals God's concern for the preservation of family identity, the protection of vulnerable widows, and the continuity of covenant promises through specific family lines. The institution connects to the broader biblical theme of redemption: just as a brother-in-law 'redeemed' the deceased brother's name and inheritance, so God redeems His people. That both Tamar and Ruth, participants in levirate-type unions, appear in the genealogy of Jesus (Matthew 1:3, 5) shows how God works through these human institutions to accomplish His redemptive purposes.
Historical Background
Levirate marriage was not unique to Israel but was practiced across the ancient Near East, including among the Hittites, Assyrians, and various tribal peoples. Similar customs are attested in Indian, Persian, and Afghan cultures, often connected to ancestor veneration and property preservation. The practice predates the Mosaic legislation, as the Tamar narrative demonstrates. In post-exilic Judaism, the practice gradually fell into disuse, though the related ceremony of halitzah (the sandal removal) continued in rabbinic Judaism as a formal release from the levirate obligation.
