Leviticus 20:21 (KJV)

What does Leviticus 20:21 mean?

Leviticus 20:21 says that if a man marries his brother’s wife, it is considered an improper and forbidden act, described as uncovering his brother’s nakedness, and the consequence is that the couple will be childless. This verse sets a clear boundary about family relationships and marriage within ancient Israel’s laws.

In this section of Leviticus, God is giving Moses specific instructions for the Israelites about sexual conduct and family boundaries. The verse uses strong language to show that marrying a brother’s wife is not just discouraged but is seen as a violation of family order and purity. The statement about being “childless” likely means that such a union is not blessed and may face consequences, either socially or in terms of descendants.

The Hebrew behind Leviticus 20:21

• "Unclean thing" (נִדָּה, niddah): This word often means something ritually impure or detestable. Here, it emphasizes that the act is not just a social issue but a serious violation of holiness.
• "Uncovered" (גָּלָה, galah): This word means to reveal or expose, and in this context, it refers to sexual relations. The phrase “uncovered his brother’s nakedness” is a way of saying he has had sexual relations with his brother’s wife, which is forbidden.
• "Nakedness" (עֶרְוָה, ervah): This term refers to sexual exposure or relations. It highlights the seriousness of the boundary being crossed.
• "Childless" (עֲרִירִי, ariri): This word means without children. In ancient Israel, being childless was seen as a significant consequence, showing the seriousness of the offense.

Why Leviticus 20:21 matters

• Leviticus 20:21 clarifies that not all marriages are acceptable, even if both people are willing; some relationships are off-limits because of family ties.
• The verse highlights the importance of respecting family boundaries, which was central to Israel’s community life and understanding of holiness.
• This law connects with other passages in Leviticus that set out forbidden relationships, showing a consistent concern for protecting family structure and community purity.
