Levítico 18

Verse-by-verse explanation

1. Levítico 18:1This opening formula introduces the chapter that organizes, in a single list, which relationships and kinships were forbidden for sexual relations within the people of Israel.
2. Levítico 18:2“I am the Lord your God” opens the chapter and repeats several times throughout — a refrain that ties every rule that follows to the authority of the one speaking, not to some ordinary custom.
3. Levítico 18:3The chapter defines itself by contrast: neither like it was done in Egypt, where the people had come from, nor like it was done in Canaan, where they were headed — the rules that follow marked an identity different from both neighboring cultures.
4. Levítico 18:4The instruction is to follow God’s own standards, not the customs of the nations named in the previous verse — the chapter presents itself as a deliberate alternative.
5. Levítico 18:5Here the law appears with a positive tone: keeping these statutes was described as something that gave life, not as a list of empty restrictions.
6. Levítico 18:6The phrase repeated throughout the chapter, uncovering someone’s nakedness, is the way of saying to have sexual relations with that person. The rest of the chapter is the detailed list of specific cases that phrase sums up: mother, sister, aunt, daughter-in-law, and so on.
7. Levítico 18:7First case on the list: relations with one’s own mother. The chapter starts with the closest possible relationship before moving on to the others.
8. Levítico 18:8The prohibition extends to the father’s wife — that is, a stepmother — even though she isn’t a blood relative of the father.
9. Levítico 18:9A sister, whether the daughter of the father or of the mother, raised in the same household or not, also makes the list — the kinship standard applied even if they hadn’t grown up together.
10. Levítico 18:10A granddaughter, whether the daughter of one’s own son or one’s own daughter, is called here “thine own nakedness” — a way of saying she was too close a relative to be treated as an outsider.
11. Levítico 18:11A half sister on the father’s side, the daughter of his wife by another relationship, is explicitly called “thy sister” — the standard was the family bond, not just sharing the same biological mother.
12. Levítico 18:12The father’s sister, that is, a paternal aunt, also makes the list of forbidden relationships.
13. Levítico 18:13The mother’s sister, the maternal aunt, follows the same rule as the paternal aunt in the previous verse.
14. Levítico 18:14The wife of the father’s brother, an aunt by marriage, is also included — kinship by marriage counted just as much as kinship by blood.
15. Levítico 18:15A daughter-in-law, the wife of one’s own son, makes the list of relationships forbidden through family ties.
16. Levítico 18:16A brother’s wife is also included — one more case of kinship by marriage covered by the same rule.
17. Levítico 18:17Having relations with a woman and, at the same time, with her daughter or granddaughters was called “wickedness,” a stronger word than those used in the earlier cases on the list.
18. Levítico 18:18This law forbids marrying two sisters at the same time while both are alive — it doesn’t address marrying the sister of a wife who has already died. The phrase “to vex her” points to the real issue: the rivalry between two sisters sharing the same husband, as had already happened between Leah and Rachel generations earlier.
19. Levítico 18:19This prohibition connects directly to the purity rules in chapter 15. During her period the woman was in a state of ritual impurity, and the law extends that pause to the couple’s sexual life as well.
20. Levítico 18:20In the middle of the list of relationships, the prohibition against relations with one’s neighbor’s wife also appears — adultery handled within the same block of rules about sexual relations.
21. Levítico 18:21Molech was a god worshipped by neighboring peoples, such as the Ammonites, and passing through the fire was a rite linked to him that other biblical texts, like 2 Kings and Jeremiah, describe as child sacrifice. Scholars debate the exact details of the ritual, but the law here strictly forbids Israelites from taking part in it.
22. Levítico 18:22This is one of the sexual laws on the list that forbids relations between men. Like the others in the chapter, it reflects Israel’s code of sexual purity set against the customs of the neighboring peoples named at the start and end of the chapter, without entering today’s debates on the subject.
23. Levítico 18:23Sexual relations with an animal were forbidden for both men and women, called “confusion” — a word used here to describe the mixing of categories that were meant to stay separate.
24. Levítico 18:24The chapter asks people not to defile themselves with any of these practices, precisely because, according to the text, it was on account of them that the earlier nations of the land were driven out.
25. Levítico 18:25The chapter ends by explaining why these laws were given: the peoples who had lived in Canaan before are described as practicing these things, and the text attributes the loss of their land to that — the framework the book itself uses to justify the list, without addressing how it is read or applied today.
26. Levítico 18:26The same rule to keep these statutes applied equally to those born in Israel and to any foreigner living among them — neither of the two abominations listed had an exception based on origin.
27. Levítico 18:27The text emphasizes: it was exactly these practices that the former inhabitants of the land committed, and that is what defiled the land before the people of Israel arrived.
28. Levítico 18:28The warning is direct: if the people repeated the same errors, the land would do to them what it did to the earlier inhabitants — the same fate, not a guaranteed privilege.
29. Levítico 18:29The penalty for anyone who committed any of these practices was the same used elsewhere in the book: being cut off from their own people.
30. Levítico 18:30The chapter closes by repeating the request from the start: keep these rules and don’t follow the customs of the earlier nations — ending with the same refrain of authority, “I am the Lord your God.”
