God’s law protects the community by affirming the sacred boundaries of family, highlighting that loyalty and respect within marriage honor both one’s spouse and the Lord.
Leviticus 20:21 addresses a very serious instruction within the broader set of moral and ceremonial laws given through Moses, who lived around 1440 to 1400 BC. In this verse, we read: “If there is a man who takes his brother’s wife, it is abhorrent; he has uncovered his brother’s nakedness. They will be childless.” (v.21). This warning focuses on preserving the sanctity of family relationships. By forbidding a man from taking his brother’s wife, the law protects the marital bond and prevents illicit unions from weakening the community’s moral fabric. In ancient Israel, upholding family integrity was critical to societal stability, so the consequence given—often understood as barrenness or an inability to pass one’s lineage onward—served as a tangible penalty for dishonoring one’s brother and violating God’s design.
When the verse says “They will be childless” (v.21), it points to God’s judgment on the offender, warning that such disobedience could result in losing the blessing of progeny. This was a profound discipline in a culture where children were seen as a direct blessing from God (Psalm 127:3). Furthermore, the phrase “he has uncovered his brother’s nakedness” (v.21) underscores the seriousness of this offense by equating it with a blatant act of dishonor. Centuries later, Jesus emphasized the sacred union of marriage, stating, “What therefore God has joined together, let no man separate” (Mark 10:9), showing continuity between the Old Testament emphasis on marital faithfulness and the New Testament’s teaching on covenant commitment.
This verse, given through Moses in the wilderness wanderings of the Israelites before entering the Promised Land, supports the overarching message that God’s people are called to be holy and to uphold godly relationships. The prohibition reflects God’s desire for purity in marriage, a theme consistent throughout both the Hebrew Scriptures and the teachings of Christ (Matthew 19:4-6).
