What are the consequences of violating the prohibitions in Leviticus 18:17? The Plain Text of the Command • “You must not have sexual relations with both a woman and her daughter. You are not to take her son’s daughter or her daughter’s daughter to have sexual relations with them. They are close relatives; this is wickedness.” (Leviticus 18:17) What Violating It Meant in Ancient Israel • The act was labeled “wickedness,” a term reserved for the most flagrant moral offenses. • It shattered God-ordained family boundaries, corrupting the relational fabric He established (cf. Genesis 2:24). • It desecrated the covenant community’s holiness, which God required for His people to remain in His presence (Leviticus 19:2). Stated Penalties in the Law • Capital judgment: “If a man marries a woman and her mother, it is depravity; both he and they are to be burned with fire, so that there will be no depravity among you” (Leviticus 20:14). • The death penalty purged the evil and served as a deterrent (Deuteronomy 13:5; 17:12). • The offender’s name and legacy were cut off from Israel—no inheritance, no standing, no place among God’s people (Numbers 15:30–31). Spiritual and Relational Fallout • Personal defilement: Sin severs fellowship with a holy God (Isaiah 59:2). • Family devastation: Trust, honor, and protection within the household collapse. • Community contamination: “You shall remove the evil from among you” (Deuteronomy 22:24) underscores corporate responsibility to confront sin. Far-Reaching National Consequences • Land defilement: “Do not defile yourselves… so the land does not vomit you out” (Leviticus 18:24-25). • Exile threat: Persisting in such sins led to eventual displacement from the Promised Land (2 Kings 17:7-18). • Loss of blessing: God withheld prosperity and protection when Israel tolerated moral corruption (Deuteronomy 28:15-68). New Testament Echoes • Sexual immorality—including incest—bars the unrepentant from God’s kingdom (1 Corinthians 6:9-10). • Paul demands church discipline for incest to “deliver such a one to Satan for the destruction of the flesh” (1 Corinthians 5:1-5). • God still calls His people to holiness: “Marriage should be honored by all, and the marriage bed kept undefiled” (Hebrews 13:4). Takeaways for Today • God’s design for sexuality is protective, not restrictive; violating it invites judgment and heartache. • Sin affects more than the individual—it wounds families, churches, and cultures. • Christ’s atonement offers forgiveness, yet genuine repentance and separation from sin remain non-negotiable (1 John 1:9). |
