Leviticus18

Leviticus 18 outlines God's commands to Israel regarding sexual purity and other abominable practices. The LORD instructs them not to follow the customs of Egypt or Canaan, but to obey His statutes. The chapter specifically prohibits various forms of incest, adultery, child sacrifice, homosexual acts, and bestiality, warning that such defilement will cause the land to expel its inhabitants.

Call to Embrace God's Statutes

1
The LORD said to Moses,
2
“Speak to the children of Israel, and say to them, ‘I am the LORD your God. ​
3
You shall not do as they do in the land of Egypt, where you lived: and you shall not do as they do in the land of Canaan, where I am bringing you; neither shall you walk in their statutes. ​
4
You shall do my ordinances, and you shall keep my statutes, and walk in them: I am the LORD your God.
5
You shall therefore keep my statutes and my ordinances; which if a man does, he shall live in them. I am the LORD. ​

Prohibited Sexual Relations (Incest)

6
“‘None of you shall approach anyone who are his close relatives, to uncover their nakedness: I am the LORD. ​
7
“‘You shall not uncover the nakedness of your father, nor the nakedness of your mother: she is your mother. You shall not uncover her nakedness.
8
“‘You shall not uncover the nakedness of your father’s wife. It is your father’s nakedness. ​
9
“‘You shall not uncover the nakedness of your sister, the daughter of your father, or the daughter of your mother, whether born at home, or born abroad.
10
“‘You shall not uncover the nakedness of your son’s daughter, or of your daughter’s daughter, even their nakedness: for theirs is your own nakedness.
11
“‘You shall not uncover the nakedness of your father’s wife’s daughter, conceived by your father, since she is your sister.
12
“‘You shall not uncover the nakedness of your father’s sister: she is your father’s near kinswoman.
13
“‘You shall not uncover the nakedness of your mother’s sister: for she is your mother’s near kinswoman.
14
“‘You shall not uncover the nakedness of your father’s brother, you shall not approach his wife. She is your aunt.
15
“‘You shall not uncover the nakedness of your daughter-in-law: she is your son’s wife. You shall not uncover her nakedness.
16
“‘You shall not uncover the nakedness of your brother’s wife. It is your brother’s nakedness. ​
17
“‘You shall not uncover the nakedness of a woman and her daughter. You shall not take her son’s daughter, or her daughter’s daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.
18
“‘You shall not take a wife to her sister, to be a rival, to uncover her nakedness, while her sister is yet alive. ​

Warning Against Other Abominations

19
“‘You shall not approach a woman to uncover her nakedness, as long as she is impure by her uncleanness. ​
20
“‘You shall not lie carnally with your neighbor’s wife, and defile yourself with her.
21
“‘You shall not give any of your children to sacrifice to Molech; neither shall you profane the name of your God. I am the LORD. ​
22
“‘You shall not lie with a man, as with a woman. That is detestable. ​
23
“‘You shall not lie with any animal to defile yourself with it; neither shall any woman give herself to an animal, to lie down with it: it is a perversion. ​

The Consequences of Defiling the Land

24
“‘Don’t defile yourselves in any of these things: for in all these the nations which I am casting out before you were defiled. ​
25
The land was defiled: therefore I punished its iniquity, and the land vomited out her inhabitants. ​
26
You therefore shall keep my statutes and my ordinances, and shall not do any of these abominations; neither the native-born, nor the stranger who lives as a foreigner among you;
27
(for all these abominations have the men of the land done, that were before you, and the land became defiled);
28
that the land not vomit you out also, when you defile it, as it vomited out the nation that was before you.
29
“‘For whoever shall do any of these abominations, even the souls that do them shall be cut off from among their people. ​
30
Therefore you shall keep my requirements, that you do not practice any of these abominable customs, which were practiced before you, and that you do not defile yourselves with them. I am the LORD your God.’”

Study Notes for Leviticus 18

Verse 2

This proclamation establishes the covenant relationship between Yahweh and Israel, emphasizing that the laws are rooted in God’s identity as their sovereign authority.

Verse 3

Israel is commanded to maintain behavioral distinction from the corrupt practices of both their recent past (Egypt) and the land they are about to enter (Canaan), reinforcing the theme of holiness.

Verse 5

The promise that 'he shall live in them' signifies covenant blessing and flourishing—physical health, prosperity, and continuation within the land, rather than a guarantee of eternal life.

Verse 6

This verse introduces the central theme of kinship prohibitions. 'Uncover their nakedness' is a common biblical euphemism for sexual intercourse.

Verse 8

This prohibition applies even if the father is deceased, indicating that marriage to a stepmother is viewed as a violation of the father’s conjugal rights and honor.

Verse 16

Generally prohibits marriage to a sister-in-law. This is distinct from the later law of levirate marriage (Deut. 25:5-10), which is a mandatory exception if the brother died childless.

Verse 18

This verse is widely interpreted as prohibiting sororal polygyny—marrying two sisters simultaneously. The explicit reasoning is pragmatic: to prevent domestic jealousy and strife ('to vex her').

Verse 19

Intercourse during a woman’s menstrual impurity (*niddah*) was forbidden because it involved contact with a powerful source of ritual defilement.

Verse 21

The prohibition against sacrificing children to Molech (likely a deity associated with the Ammonites) is categorized as profaning God’s name, as it links Yahweh's people with horrific pagan rites.

Verse 22

This is a key prohibition against male homosexual intercourse, classified as *to'evah* ('abomination'), denoting something ritually and morally repugnant to God and the covenant community.

Verse 23

Bestiality is prohibited as 'confusion' (*tevel*), signifying the blurring and destruction of the divinely established boundaries between human and animal life.

Verse 24

These sexual and ritual sins are identified as the very acts that led to the defilement of the Canaanite nations, justifying God’s judgment upon them.

Verse 25

The land is personified: it becomes ritually defiled by the inhabitants' sin and eventually 'vomits out' those who corrupt it, establishing a direct link between moral behavior and territorial security.

Verse 29

The penalty for committing these specific abominations is to be 'cut off,' which typically means excommunication from the covenant community, often resulting in premature death or execution.
