Leviticus 20:17 Meaning: Why Incest Brings 'Cut Off' Not Death
“‘If a man takes his sister—his father’s daughter, or his mother’s daughter—and sees her nakedness, and she sees his nakedness, it is a shameful thing. They shall be cut off in the sight of the children of their people. He has uncovered his sister’s nakedness. He shall bear his iniquity.
And if a man shall take his sister, his father’s daughter, or his mother’s daughter, and see her nakedness, and she see his nakedness; it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister’s nakedness; he shall bear his iniquity.
And if a man shall take his sister, his father’s daughter, or his mother’s daughter, and see her nakedness, and she see his nakedness; it is a shameful thing; and they shall be cut off in the sight of the children of their people: he hath uncovered his sister’s nakedness; he shall bear his iniquity.
`And a man who taketh his sister, a daughter of his father or daughter of his mother, and he hath seen her nakedness, and she seeth his nakedness: it is a shame; and they have been cut off before the eyes of the sons of their people; the nakedness of his sister he hath uncovered; his iniquity he beareth.
And if a man take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness, that is a disgrace; and they shall be cut off before the eyes of the children of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity.
Meaning in one sentence
Leviticus 20:17 prohibits incest with a sister and prescribes being 'cut off.' Understand this penalty's meaning and why it differs from death in the
Context
Leviticus 20 assigns penalties for the sexual sins listed in chapter 18. Most carry death: adultery, homosexuality, bestiality. But the incest between a man and his sister, full or half, receives a different penalty: being “cut off in the sight of the children of their people.” This phrase likely means a public excommunication, perhaps expulsion from the community, possibly death by divine hand. The man, not the woman, explicitly “bears his iniquity.” The chapter consistently protects family boundaries. Earlier verses protected the parent-child and in-law relationships with death; this verse protects the sibling relationship with a severe but distinct punishment. The whole chapter calls Israel to a holiness that mirrors God’s own character, separating them from the practices of Egypt and Canaan.
Key Words
Three Hebrew words explain the weight of this sin. First, the word for “nakedness” (ervah) appears repeatedly in these chapters. It means more than physical nudity; it carries the sense of shameful exposure, something that should remain covered. The verse uses it three times, emphasizing that this is a violation of a boundary God Himself built into creation. Second, the phrase “shameful thing” translates the Hebrew word chesed. This is the same word that often describes God’s steadfast love. But here it takes its opposite meaning: a disgrace, a reproach. What should be a beautiful bond of love between siblings has become something ugly and exposed. The word itself holds a tension, love twisted. Third, “cut off” (karat) is the penalty. The verb suggests a violent severing, being cut out of the community. It can mean death, but more specifically, being removed from the covenant people. To be cut off was to lose your place in the family of God.
How Christians Read This Verse
Christians across traditions agree on the clear prohibition of incest in this verse, but they have understood the penalty differently. Protestants like Matthew Henry and Gill saw “cut off” as death, likely by stoning or divine judgment. The Geneva Bible called it “villenie” and read the cutting off as public execution. Barnes suggested a different reading: a form of excommunication, perhaps expulsion from the camp without the death penalty. Wesley emphasized that “uncovering nakedness” refers to any sexual relationship, not just marriage. Historic Christian teaching holds that God’s moral law established these boundaries for families before Sinai. What all agree on: incest violates God’s design for close family relationships and brings serious consequences.
A common misunderstanding
Many readers assume that “cut off” is a lighter sentence, just being kicked out of church. In fact, the Hebrew verb karat suggests a violent cutting off, often by death. As Barnes notes, it likely included expulsion from the camp, but Gill argues it could mean death by the hand of God, like the plague. Whether through the community’s action or God’s direct judgment, this punishment ended a person’s place among the covenant people, a devastating consequence in ancient Israel.
Living This Out
This week, consider the boundaries God has drawn in your closest relationships. Not just sexual boundaries, but all the limits that keep love safe: the boundary between husband and wife that protects marriage; the boundary between parent and child that guides discipline; the boundary between siblings that keeps natural affection pure. The verse calls you to honor God’s design rather than look for loopholes. If there is a relationship in your life where the lines have blurred, where affection has become ownership, or closeness has become inappropriate, ask God to help you restore the boundary. His restrictions are not obstacles. They are the fences around a garden.
Main takeaway: God’s boundaries in close family relationships protect the community’s holiness and prevent a good bond from becoming a shameful one.
For Families
For ages 5, 8
God made families to be close and loving. But some kinds of closeness are not okay. This verse tells us that brothers and sisters should love each other as family, not take care of each other like married people do.
For ages 9, 12
God’s law in Leviticus protects the special bond between siblings. Brothers and sisters are meant to grow up together in friendship and care, not to become like husband and wife. God draws this boundary because incest hurts families deeply and confuses the roles God designed. Even in a world where many people ignore these rules, God’s people are called to honor His design for family relationships.
Questions People Ask
Why is the penalty “cut off” for incest with a sister but death for other sexual sins in Leviticus 20?
Some scholars suggest that incest between siblings, while a serious sin, was considered less severe than adultery or homosexuality in that cultural context. The word translated “shameful thing” suggests a disgrace rather than an abomination. Others note that the penalty “cut off” could still mean death, perhaps by divine judgment or community action, but it is explicitly differentiated from the direct death penalty commands elsewhere in the chapter.
Does this verse prohibit marriage between cousins?
No, this verse specifically addresses siblings, father’s daughter or mother’s daughter. Leviticus 18 and 20 list prohibited relationships including siblings, parents, children, aunts, and uncles. Cousins are not listed among the forbidden relationships, though some Christian traditions have extended the principle based on broader interpretations of kinship. Most Christians do not see cousin marriage as forbidden by this passage.
What does the Hebrew word “chesed” mean in this verse and why does it seem to contradict its normal meaning?
In most of the Old Testament, chesed means steadfast love, mercy, or lovingkindness. In Leviticus 20:17, however, it takes the opposite meaning: a shameful thing, a disgrace. The word can carry a sense of reproach or contempt. It is as if the bond of love has been perverted into something that brings shame.
