Leviticus 18:20
“You shall not have sexual intercourse with your neighbor's wife, nor shall you be defiled by the mingling of seed.”
Verse Explanation
A saved explanation for Leviticus 18:20.
Plain-language explanation
Leviticus 18:20 commands God’s people not to commit adultery or sexual relations with a neighbor’s wife. It also warns against becoming “defiled” by the consequences and disorder that come from such actions—presented here as the harmful “mingling” of sexual activity.
Catholic context
In Catholic teaching, this verse is part of the Old Testament moral law that guards chastity and the dignity of marriage. Many Catholics understand these commands as protecting not only personal purity, but also the good of spouses, families, and the common good.
Historical background
This law was given to ancient Israel as they lived within a wider world that included serious sexual practices outside covenant faithfulness. In that context, adultery threatened the stability of households and violated the covenant responsibility owed to a spouse. The language uses “seed” to refer to sexual relations and their consequences.
Reflection
God’s command is not merely about rules; it’s about protecting love so it can be true, faithful, and life-giving. When sexual desire is separated from covenant commitment, it can leave deep damage. This verse invites us to trust that God’s boundaries are for our good.
Practical takeaway
Guard your heart and choices: avoid situations that lead to temptation, practice modesty and self-control, and if you are struggling, seek support (a trusted priest, counselor, or Catholic support resources) rather than handling it alone.
Prayer
Lord God, help me respect the bonds of marriage and live with chastity of heart and body. Teach me to keep firm boundaries, to flee temptation, and to honor the dignity of every person. Give me courage to choose what is faithful and true. Amen.
