Leviticus 18
Leviticus 18 — Commentary and Meaning
The short answer
Leviticus 18 is best known for its long list of forbidden sexual relationships, each introduced with the phrase about not uncovering someone's "nakedness." That phrase is a way of talking about having sex with someone, and the chapter bans a wide range of relationships within a person's own household — with close relatives, with relatives by marriage, and beyond.
It is tempting to read the list as a chapter about biology, but that misses what it is doing. Ancient Israelite households were large and layered: multiple generations, in-laws, servants, and dependents living under one roof, with real differences in power between them. Sex inside that web was rarely just a private matter between two people. It could destabilize the whole household and become a tool of domination — think of Absalom sleeping with his father David's secondary wives as a public claim to David's throne. Leviticus 18 draws firm boundaries so that the home remains a place of safety rather than a field of predation.
At the chapter's hinge stands verse 5: keep these statutes and ordinances, for the one who does them "shall live in them." That single line reframes everything that follows. The commands are not an arbitrary catalog of prohibitions; they are presented as a path to life, given to a people rescued from Egypt and headed for a land with its own corrupting customs. The New Testament keeps circling back to this verse — Paul quotes it in Romans and Galatians — because it captures the Torah's whole promise: obedience leads to life, rebellion leads to death and exile. Read that way, Leviticus 18 becomes part of a much bigger story that stretches from Adam in the garden to Israel in the land, a story about what it takes for human community to flourish.
What scholars say
John Goldingay unpacks what the language of "revealing nakedness" means and argues that these bans guard the household against disruption and abuses of power — pointing to Absalom's story — rather than policing biology. N.T. Wright then shows how Leviticus 18:5's promise of life for those who keep the Torah sets Israel's story alongside Adam's, where breaking the command led to death and banishment.
“Overlapping dynamics underlie the concern about sexual relationships in Leviticus 18. “Revealing someone’s nakedness” is a term for having sex with them, and the chapter bans a wide range of sexual relationships with one’s own flesh—that is, within the household, such as the relationship I have just described. Its concern is not that the relationships are biologically incestuous, and as well as extramarital sex its ban would cover marriage (for instance, after a woman’s original husband had died). Such relationships threaten disruption within the household and raise questions about power such as are illustrated in the story of Absalom and his father’s secondary wives, with whom he has sex as a sign of claiming to take over David’s position. Both this chapter and that story illustrate how we have to think of the family in the Old Testament in a different way from the one that is customary in the West.”
“Again and again, but particularly in passages like Leviticus 18.5 and Deuteronomy 30.15–20, the Torah held out to Israel the promise that those who faithfully observed it would enjoy life, while those who broke it would incur death. Already in the Old Testament a parallel emerges between Israel, given the law and promised the land, and Adam and Eve, placed in the garden and given a commandment with a warning attached: to break this means death. The ‘death’ in question involved banishment from the garden, just as Israel’s punishment ended in exile . But this was not the fault of the commandment given in the garden, or of the law given to Israel. It was the result of sin.”
What it means for you
Leviticus 18 asks modern readers to think about sex less as a purely private choice and more as something that shapes — or shatters — the community around it. Its instinct to protect the vulnerable within a household from disruption and predatory power speaks directly to families, churches, and workplaces today, where abuses of intimacy and abuses of power so often travel together.
And verse 5 reframes obedience itself. God's commands here are not offered as a burden or a test to fail, but as a description of the kind of ordered, trustworthy life in which people can actually thrive. The question the chapter poses is not "how much is forbidden?" but "what makes life possible?"
Leviticus 18 in context
Leviticus 18 sits within the section often called the Holiness Code (roughly Leviticus 17–26), where the focus shifts from sacrifices and priests to the everyday life of the whole community. The chapter opens with God telling Israel not to copy the practices of Egypt, where they had lived, or Canaan, where they were going, but to keep his statutes and live by them. Then comes the list of forbidden relationships, along with bans on child sacrifice and other practices. It closes with a warning: these things defiled the land's previous inhabitants, and the land "vomited out" those who lived that way.
