Leviticus 20
Chapter twenty provides the penalty framework for the violations described in chapters 18 and 19. The most severe penalties — death by stoning, burning, or cutting off — address the most fundamental covenant violations: child sacrifice to Molek, adultery, a man's sex with his father's wife or daughter-in-law, male same-sex intercourse, sex with both a woman and her mother, bestiality, and cursing parents. The death penalties for adultery and the various sexual violations are all bilateral — both parties are held responsible. Certain violations carry the lesser penalty of childlessness (the uncle's wife, the sister-in-law) rather than death, communicating a graduated range of sanctions. The theological grounding is stated three times: be holy, for I am holy; I have set you apart from the nations to be my own; you must make a distinction between clean and unclean animals. The chapter communicates that holiness is not optional sentiment but a covenant obligation with real consequences — the same holiness that produces the blessings of chapter 26 when honored produces the curses of chapter 26 when rejected.
Leviticus 20:1
The Lord said to Moses. Leviticus 20 provides the penalty framework for the violations addressed in the previous two chapters: where Leviticus 18 stated the prohibited practices and Leviticus 19 stated the positive ethical requirements, Leviticus 20 assigns specific penalties to the most serious violations. The chapter moves from the ethical description to the legal sanction. The penalties range from death to cut off to various degrees of community sanction. The severity of the penalties communicates the severity of the violations.
Leviticus 20:2
Say to the Israelites: any Israelite or any foreigner residing in Israel who sacrifices any of his children to Molek is to be put to death. The members of the community are to stone him. The child sacrifice penalty is the most severe in the chapter: death by stoning, carried out by the community. The stoning by the community members communicates that the covenant community bears collective responsibility for enforcing the most serious covenant violations. The community that permits child sacrifice in its midst becomes complicit in the abomination; the stoning that the community performs is the community's renunciation of that complicity.
Leviticus 20:3
I myself will set my face against him and will cut him off from his people; for by sacrificing his children to Molek, he has defiled my sanctuary and profaned my holy name. The divine first-person enforcement: I myself will set my face against him and cut him off. The divine response to child sacrifice is the profanation of the sanctuary and the holy name — child sacrifice defiles the holy space and profanes the holy name even if no human sanction is applied. The dual consequence (human stoning and divine cutting off) communicates the absolute nature of the prohibition: the community must enforce it, and God enforces it regardless of whether the community does.
