Leviticus 20 is a chapter about holiness, and it sets out what that holiness looks like in daily life for the people of Israel. People read it to understand why God lays down such severe penalties for certain sins, how it fits with the rest of the Bible, and what, if anything, it asks of Christians today. This study walks through the chapter verse by verse, explains its historical setting, and suggests how its themes can be applied now.
Leviticus 20 Summary
The chapter opens with God speaking to Moses and instructing him to tell the Israelites what God requires. It begins with a stern warning against offering children to Molech, a Canaanite deity, and against consulting mediums and spiritists. Those who take part in these practices are described as turning away from the Lord, and God says he will set his face against them.
The middle of the chapter moves into a list of sexual and family offenses, from adultery to various forms of incest and sexual relations between people of the same sex or with animals. Each is named and paired with a consequence, showing that God takes the covenant community’s moral life seriously. The chapter closes by tying these laws back to the land and to God’s call for Israel to be a people set apart from the nations around them.
Background and Setting
Leviticus is the third book of the Pentateuch, the five books traditionally attributed to Moses. Its laws are given at Mount Sinai, after Israel has been delivered from Egypt and before the people enter the Promised Land. Most scholars regard the book’s final form as coming from the period after the Exodus, though Jewish and Christian tradition has long credited the content to Moses as the mediator of God’s instruction.
The book was written first for the priests and the people of Israel living in covenant with God. Chapter 20 follows the instructions on sacrifice and priestly conduct in chapters 18 and 19 and continues the theme of holiness, showing that the rules governing worship and everyday life belong together in a single vision of a holy community.
Leviticus 20 Section by Section
Verses 1-6: Warnings Against Child Sacrifice and Idolatrous Practice
2 “Moreover, you shall tell the children of Israel, ‘Anyone of the children of Israel, or of the strangers who live as foreigners in Israel, who gives any of his offspring to Molech; he shall surely be put to death. The people of the land shall stone him with stones. 3 I also will set my face against that person, and will cut him off from among his people because he has given of his offspring to Molech, to defile my sanctuary, and to profane my holy name.
Leviticus 20:2-3 (WEB)
The chapter begins with a direct command that anyone who gives a child to Molech must be put to death. The seriousness of the offense is clear, and God says the act defiles his sanctuary and profanes his holy name. The problem is not only the cruelty of the act but the way it pulls the community away from the God who has chosen them.
The section also warns about turning to mediums and spiritists. God describes such turning as a kind of spiritual adultery, a betrayal of the covenant relationship. The passage shows that worship of God is exclusive, and that any attempt to find guidance or security through other spiritual powers is a rejection of the Lord himself.
Verses 7-8: The Call to Be Holy
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)
These two verses form the hinge of the chapter. Immediately after the warnings, God calls the people to sanctify themselves and be holy, because he is the Lord their God. Holiness here is not a mood or an inward feeling alone but a way of living that reflects God’s own character and separateness.
The reason given is important. The people are not asked to be holy in order to earn God’s favor; rather, God says he is the one who sanctifies them. Obedience to his statutes is the response to a relationship already established by his grace.
Verses 9-16: Family Honor and Sexual Boundaries
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)
The laws in this section deal with honor within the household and with faithfulness in marriage. Cursing one’s father or mother and adultery are both treated as grave offenses, reflecting the high value Israel placed on the family as the foundation of its common life. Each law names the wrong clearly, without softening it.
The subsequent verses extend these concerns to sexual relations within close family ties and to other acts the text calls wickedness or abomination. Whatever one makes of their harshness, the section shows that God’s concern reaches into the most private areas of life and that the community’s health depends on faithful and ordered relationships.
Verses 17-21: Restrictions on Close Kinship
“‘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)
This passage addresses sexual relations with close relatives, including siblings, aunts, uncles, and in-laws. The language emphasizes uncovering nakedness, a common biblical expression for sexual intimacy, and the text stresses that such acts bring guilt and consequences on those involved.
The section helps explain the pattern of boundaries running through the chapter. The family was meant to be a place of trust and protection, and these laws were designed to guard it from the disorder that would weaken the community as a whole.
Verses 22-27: Living Apart From the Nations
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 20:23-24 (WEB)
The chapter closes by returning to the land and to Israel’s identity. God tells the people to keep his statutes and not to walk in the customs of the nations he is driving out before them. The reason given is that those nations practiced these things, and God abhorred them. Israel’s separateness is therefore a matter of its vocation, not mere cultural preference.
The final verses restate the central claim: the people are to be holy because the Lord is holy, and he has set them apart. The chapter ends where it began, with God’s own character as the standard and the source of his people’s life.
Key Themes in Leviticus 20

- Exclusive worship: Turning to Molech, mediums, or wizards is presented as a betrayal of the covenant with the Lord.

- Divine justice: The chapter shows God taking sin seriously and refusing to allow evil to go unanswered within his people.
Lessons From Leviticus 20 for Today
Many readers find the penalties in this chapter difficult, and it is fair to say so. Christians have long read these laws in light of Jesus, who fulfilled the law and taught that love and mercy sit at its heart. Still, the underlying concern for holiness remains. A believer today might ask whether their daily choices, in how they honor their parents, keep their marriage faithful, or guard their household from harm, reflect a life set apart for God.
The chapter also speaks to the pull of other sources of security. When someone is anxious about the future, the temptation may be to seek reassurance from horoscopes, online fortune-tellers, or other substitutes for trust in God. Leviticus 20 reminds us that such turning aside matters, because it moves the heart away from the One who sanctifies his people.
