Leviticus 20 explains which practices God regarded as violations of holiness, and what the community was to do about them. Many readers come to this chapter because its penalties seem severe and its subject matter unfamiliar, and they want to know how it fits with the rest of Scripture. The short answer is that the chapter is a legal section about protecting a people set apart for God, and its sharpest words are aimed at idolatry, sexual corruption, and the abuse of the vulnerable.
Leviticus 20 Summary
The chapter opens with God speaking to Moses and giving instructions for the people of Israel. It begins with the worship of Molech, a pagan deity to whom children were sacrificed, and it sets out the consequences for those who participate in it or ignore it. From there the chapter turns to occult practices, then to offenses against family, including cursing parents and various forms of sexual wrongdoing. Verses 22 to 26 bring the argument together: Israel must keep God’s statutes so that the land will not reject them, and must be distinct from the nations around them.
The closing verse returns to the theme of mediums and wizards, which frames the chapter’s end with the same concern it began with. The shape of the chapter is a movement from worship to household to nation, with holiness as the thread running through all three.
Background and Setting
Leviticus is the third book of the Pentateuch, the first five books of the Old Testament. Jewish and Christian tradition has long attributed the law within it to Moses, and it presents itself as instruction given at Mount Sinai as Israel prepared to enter the promised land. Most scholars date its final form to the post-exilic period, though many agree that much of the legal material reflects earlier practice.
The book was written for a community of former slaves who were learning to live as God’s covenant people. Chapter 20 sits within the section of Leviticus often called the Holiness Code, which runs roughly from chapters 17 to 26. Its laws are meant to show that the nation’s daily life, not only its worship, belongs to God.
Leviticus 20 Section by Section
Verses 1-8: The Call to Holiness
7 “‘Sanctify yourselves therefore, and be holy; for I am the LORD your God. 8 You shall keep my statutes, and do them. I am the LORD who sanctifies you.
Leviticus 20:7-8 (WEB)
The chapter opens with a warning about child sacrifice to Molech, which God says defiles His sanctuary and profanes His name. The penalty is death, and God declares that He Himself will turn against anyone who protects such a person. The section then shifts from prohibition to invitation. God calls Israel to sanctify themselves and be holy, because He is the Lord who sanctifies them. Holiness here is not a mood but a way of living that reflects who God is.
The reader should notice that holiness is grounded in relationship. Israel is told to be holy because God is holy and because He has chosen them. The commands that follow are best understood as the outworking of that identity rather than a list of arbitrary rules.
Verses 9-16: Family, Sexuality, and Covenant Order
9 “‘For everyone who curses his father or his mother shall surely be put to death: he has cursed his father or his mother; his blood shall be upon him. 10 “‘The man who commits adultery with another man’s wife, even he who commits adultery with his neighbor’s wife, the adulterer and the adulteress shall surely be put to death.
Leviticus 20:9-10 (WEB)
“‘If a man lies with a male, as with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
Leviticus 20:13 (WEB)
This section addresses cursing parents, adultery, and several forms of sexual wrongdoing, including relations with a father’s wife, a daughter-in-law, a man, a woman and her mother, and animals. The chapter treats these acts as violations of the created order and of the bonds that hold a household together. The penalties are severe, reflecting how seriously the community was to guard family life.
Readers often find these verses difficult, and it helps to remember that ancient Israel lived under a legal system where the death penalty was applied only after due process. The text’s purpose is to show how grave the breakdown of family and sexual integrity appears to God, not to invite cruelty in any age.
Verses 17-21: Relationships and Consequences
“‘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.
Leviticus 20:17 (WEB)
“‘If a man takes his brother’s wife, it is an impurity. He has uncovered his brother’s nakedness. They shall be childless.
Leviticus 20:21 (WEB)
These verses address incest within the extended family and the taking of a brother’s wife. The language of uncovering nakedness is a Hebrew idiom for sexual relations within forbidden kinship lines. The passage stresses that such acts bring guilt that the person must bear, and that they disrupt the family line.
The section makes clear that God’s concern extends beyond individual acts to the health of the wider community. Sin within one household shapes the future of everyone connected to it.
Verses 22-26: Living Distinctly Among the Nations
22 “‘You shall therefore keep all my statutes, and all my ordinances, and do them; that the land, where I am bringing you to dwell, may not vomit you out. 23 You shall not walk in the customs of the nation, which I am casting out before you: for they did all these things, and therefore I abhorred them. 24 But I have said to you, “You shall inherit their land, and I will give it to you to possess it, a land flowing with milk and honey.” I am the LORD your God, who has separated you from the peoples.
Leviticus 20:22-24 (WEB)
You shall be holy to me; for I, the LORD, am holy, and have set you apart from the peoples, that you should be mine.
Leviticus 20:26 (WEB)
Here the chapter explains why all these laws matter. God has separated Israel from the nations and promises them the land, but the land will respond to their conduct. The image of the land vomiting out its inhabitants shows that moral failure carries consequences for the whole nation. Israel is to walk differently from the peoples around them, and the distinction between clean and unclean is part of that witness.
The emphasis is on belonging. Verse 26 says that God has set Israel apart so that they would be His. Holiness marks the people as God’s possession.
Verse 27: The Closing Warning
“‘A man or a woman that is a medium, or is a wizard, shall surely be put to death: they shall stone them with stones. Their blood shall be upon them.’”
Leviticus 20:27 (WEB)
The chapter ends as it began, with a strong warning about mediums and wizards. Seeking guidance through the occult was a direct rival to trust in the Lord, and the penalty reflects that seriousness. The bookend structure reminds the reader that the whole chapter concerns where a person places their ultimate loyalty.
Key Themes in Leviticus 20
- Holiness: God calls His people to be set apart in worship, family, and daily conduct because He is holy.
- Covenant identity: Israel’s laws flow from their relationship with the Lord who chose them.
- Protection of the vulnerable: Child sacrifice, family abuse, and exploitation are treated as grave offenses against the community.
- Consequences of sin: Moral failure affects individuals, families, and the land itself.
Lessons From Leviticus 20 for Today
Few modern readers face the exact practices described here, but the chapter’s underlying concern remains relevant. Consider a family where a parent’s casual dishonor toward a child slowly erodes trust. The chapter reminds us that the health of relationships within a household matters deeply to God, and that small patterns can shape a whole generation.
The call to holiness also speaks to how we spend our attention. In a culture that offers constant access to guidance, entertainment, and reassurance from many sources, the chapter asks where we seek our security. Its warning about mediums invites an honest look at the things we turn to when we want answers apart from God.
Finally, the chapter shows that God takes injustice seriously. Anyone who has watched a vulnerable person be harmed will recognize the concern behind these laws, and can take heart that the God who gave them still opposes every form of exploitation today.

A Prayer From Leviticus 20
Lord, you are holy, and you have called me to be holy too. I confess that I often treat my daily choices as separate from my faith, and that I look to other sources when I feel uncertain. Show me where my loyalties have drifted, and give me the courage to turn back to you. Protect the children and the vulnerable in my life, and help me honor the families you have given me. Let my life reflect the difference you have made in me. Amen.
