Leviticus 18

The chapter moves from the general principle of distinction to specific categories of prohibited sexual behaviors, culminating in a severe warning regarding the consequences of national defilement.

• If a man keeps God's statutes and judgments, he shall live in them (Leviticus 18:5).

• Do not follow the doings of Egypt or Canaan (Leviticus 18:3).
• Do not uncover the nakedness of near kin (Leviticus 18:6).
• Do not let seed pass through fire to Molech (Leviticus 18:21).
• Do not commit the abominations that defile the land (Leviticus 18:26).

• Defiling the land leads to it vomiting out its inhabitants (Leviticus 18:25, 28).
• Those who commit these abominations shall be cut off from among their people (Leviticus 18:29).

• The setting is the wilderness during the Exodus, as Israel prepares for the conquest of Canaan.
• These laws served as a necessary counter-cultural identity for a people emerging from long-term dwelling in Egypt (mizrayim).

• The prohibitions against 'uncovering nakedness' (ervah, H6172) provided a moral hedge against the practices of neighboring ancient Near Eastern cultures, which often lacked such strict incest codes.
• The reference to 'passing children through the fire' to Molech refers to child sacrifice, a horrific practice intended to appease specific deities, which Israel is strictly forbidden to adopt.

• Leviticus 18 functions as the opening of the 'Holiness Code' (chapters 17-26), shifting from sacrificial regulations to the practical application of holiness in daily life.
• It provides the ethical basis for the land occupancy mentioned in later history.

• The principle of 'doing' and 'living' (v. 5) is later cited by the Apostle Paul in Romans 10:5 and Galatians 3:12 to contrast the principle of works-based righteousness under the Law with the righteousness that comes by faith.
• The imagery of the land 'vomiting out' its inhabitants is a recurring motif in Old Testament judgment language (e.g., Leviticus 20:22).

• Ezekiel 20:11-13 references these 'statutes' and 'judgments' (mishpat, huqqah) as the means by which a person might live, reflecting the language of Leviticus 18:5.

• עֶרְוָה (ervah, H6172): Derived from a root meaning to denude or strip, specifically used here for 'nakedness' or 'pudenda'. It carries the nuance of uncovering something that should remain hidden/protected, and thus serves as a euphemism for forbidden sexual relations.
• מִשְׁפָּט (mishpat, H4941): Properly a 'verdict' or 'decree'. When God gives His mishpatim, He is exercising His judicial right to define what is just.
• חֻקָּה (huqqah, H2708): An 'enactment' or 'appointment'. It implies a statute set by an authority that is not subject to debate.
• Matthew Henry observes that 'close and constant adherence to God's ordinances is the most effectual preservative from gross sin,' noting that God's grace secures the believer only through the path of His means and commands.

• The prohibition in verse 18 against marrying a wife's sister 'in her life time' implies a moral concern regarding familial harmony and 'vexing' (causing distress) within the family unit.
• The sexual prohibitions are gender-neutral in their application (v. 22-23), indicating that these laws concern the fundamental morality of God's creation order, not merely social conventions of the time.

• While the prohibition of Molech (v. 21) is clear, the exact cultic rituals associated with passing children 'through the fire' remain a subject of historical debate, though the text clearly defines it as an 'abomination' (toebah) that profanes the name of God.
