Meaning of Leviticus 20:17

Leviticus 20:17 prohibits sexual relations between a man and his sister, defining it as a severe offense punishable by exclusion from the community and personal culpability for the disgrace inflicted. This prohibition is rooted in the holiness code of Leviticus, which meticulously outlines laws designed to set the Israelite people apart as distinct and consecrated to God. The text explicitly labels this act as a "disgrace" (Hebrew: qelalah), signifying a profound violation of the natural order and a defilement that contaminates the community. The consequence of being "publicly removed from their people" underscores the severity of this sin, emphasizing its disruptive and polluting nature within the covenant community. The verse also highlights the personal responsibility of the man, stating he "will be held responsible" for dishonoring his sister, indicating that the act not only contravenes divine law but also inflicts a moral and social injury.

Context and Background

This verse is situated within Leviticus chapters 18 and 20, which detail prohibitions against various sexual relationships deemed incestuous or otherwise defiling. These laws are presented as directives from God to Moses, intended to guide the Israelites in living a life of holiness, distinct from the practices of surrounding nations. The prohibition against marrying one's sister is a specific instance of a broader principle of maintaining the sanctity of familial relationships and avoiding sexual relationships that blur essential social and biological boundaries. The context emphasizes a desire for purity and order within the newly formed Israelite nation, which was to be a holy people set apart for God.

Key Themes and Messages

Several key themes emerge from this verse:

• Holiness and Purity: The overarching theme is the call for the Israelites to be holy, mirroring God's holiness. This includes maintaining sexual purity and avoiding practices that would defile them.
• Distinction from Surrounding Nations: The laws in Leviticus often served to differentiate Israel from the Canaanite and Egyptian cultures, whose sexual practices were often considered licentious and idolatrous.
• Sanctity of Family: The prohibition reinforces the importance of maintaining clear boundaries within the family unit, preventing the disruption and confusion that incestuous relationships would create.
• Consequences of Sin: The verse clearly outlines severe consequences for violating this law, both communal (public removal) and personal (being held responsible).
• Dignity and Honor: The act is described as a "disgrace" and a dishonoring of the sister, highlighting the inherent dignity of individuals and the violation of that dignity through such acts.

Spiritual Significance and Application

Spiritually, this prohibition speaks to the need for ordered, pure relationships that reflect God's design. In a broader sense, it underscores the principle that God's people are to live by His standards, which often involve abstaining from practices that are harmful, disordered, or that blur essential distinctions. For believers today, while the specific ceremonial laws of Leviticus are not directly binding in the same way, the underlying principles of sexual purity, the sanctity of marriage and family, and the avoidance of practices that defile the body and spirit remain relevant. The verse calls for a discerning approach to relationships and a commitment to living in a manner that honors God and respects the dignity of others.

Relation to the Broader Biblical Narrative

This prohibition is part of the foundational legal framework given to Israel, shaping their identity as a people chosen by God. It contributes to the narrative of God establishing His covenant people and providing them with the laws necessary to live as a distinct and holy nation. The emphasis on purity and separation from idolatrous practices continues throughout the Old Testament, influencing the prophetic messages and the historical accounts of Israel's faithfulness and unfaithfulness. In the New Testament, while the emphasis shifts to spiritual holiness through Christ, the principles of sexual purity and the sanctity of marriage are reiterated by Jesus and the apostles (e.g., Matthew 5:27-28, 1 Corinthians 6:18-20, Hebrews 13:4).

Analogies

One analogy for the severity of this prohibition is that of a disease that infects the body politic. Just as a contagious disease can weaken and destroy a community, incestuous relationships were seen as a spiritual and social contagion that would corrupt the nation and incur God's judgment. Another analogy could be found in the realm of architecture: just as certain structural flaws can undermine the integrity of a building, incestuous relationships were seen as a fundamental flaw in the social structure of the family and community, threatening its stability and its ability to stand.

Relation to Other Verses

This verse is closely related to several other Levitical passages:

• Leviticus 18:6-18: This section provides a more extensive list of prohibited sexual relationships, including those with close relatives. Verse 17 is a specific instance within this broader prohibition.
• Leviticus 18:29: This verse warns against defiling oneself by any of these practices, emphasizing the widespread negative impact of such actions on the land and the people.
• Deuteronomy 27:20: This passage reiterates a similar prohibition concerning relations with one's father's wife, highlighting the consistent emphasis on familial sexual boundaries across different legal contexts.
• 1 Corinthians 5:1-5: In the New Testament, Paul addresses a case of incest within the Corinthian church, calling for the excommunication of the offender. While the specific relationship differs, the principle of addressing and removing severe sexual immorality from the community to maintain its purity is evident.
