Leviticus 20 completes the Holiness Code’s central triptych. Lev 18 listed the prohibitions in apodictic form (“Thou shalt not…”); Lev 19 issued the positive holiness-program with the neighbour-love command at its center; Lev 20 returns to the prohibitions in casuistic form (“If a man… he shall surely be put to death”) with explicit penalties attached. The chapter has four major movements: the Molech-penalty cluster (20:1-8), the capital-penalty list (20:9-21), the closing exhortation and separation-rationale (20:22-26), and the familiar-spirits postscript (20:27).
The Molech penalty (20:1-8). The chapter opens with the most severe single penalty in the OT’s casuistic legislation: child-sacrifice to Molech results in death by stoning, with the additional severity that the LORD will personally “set my face against that man, and will cut him off from among his people” (20:5). The chapter then extends the penalty to anyone who tolerates the practice without acting against it (20:4-5 — community-complicity addressed). The pivot to Leviticus 20:6–8↗ picks up familiar-spirits and wizardry (later returned to at 20:27) and the holiness imperative: “Sanctify yourselves therefore, and be ye holy: for I am the LORD your God.”
The capital-penalty list (20:9-21). The chapter’s main casuistic section, paralleling Lev 18’s prohibitions with attached consequences. Cursing father or mother (20:9 — the OT’s strongest single statement of parental honour, picked up by Christ’s polemic against the corban evasion at Mark 7:9–13↗); adultery (20:10 — both parties); various incest-pairings (20:11-21); male homosexual intercourse (20:13); bestiality (20:15-16); intercourse during menstruation (20:18). The chapter distinguishes two penalty-vocabularies. (“he shall surely be put to death”) signals court-imposed capital penalty. (“cut off from his people”) signals a divinely-administered penalty whose precise nature is disputed in standard commentary — death without progeny, divine death, exclusion from the community.
The closing exhortation and separation-rationale (20:22-26). The chapter’s most theologically distinctive single closing: Leviticus 20:22↗ — “Ye shall therefore keep all my statutes, and all my judgments, and do them: that the land, whither I bring you to dwell therein, spue you not out” — the Lev 18:25 land-vomits warning now in second person (Lev 18 had used third person about the previous inhabitants; Lev 20 turns the warning directly on Israel). The chapter closes with the chapter’s identity-statement: Leviticus 20:26↗ — “ye shall be holy unto me: for I the LORD am holy, and have severed you from other people, that ye should be mine.” The clean-and-unclean food laws of Lev 11 are invoked as the everyday vehicle of the people’s awareness of this distinction (20:25). The triptych closes with the identity-claim that grounded the program: holiness is not merely behavioural compliance but covenant identity — the LORD has “severed” Israel from other peoples, and the chapter’s prohibitions guard the boundary He has drawn.
The familiar-spirits postscript (20:27). The chapter’s final verse returns to the necromancy issue raised at 20:6, now with the death-penalty attached. The placement signals that traffic with familiar spirits is theologically equivalent to the Molech-cult of the chapter’s opening — both involve appropriating life or knowledge through prohibited spirit-channels.
Language & Translation Notes
The triptych structure of Lev 18-19-20. Leviticus 18, 19, and 20 form one of the Pentateuch’s most-deliberate single literary patternings. Lev 18: prohibitions in apodictic form (“Thou shalt not uncover the nakedness of…”), without penalties, ending with the third-person land-vomits warning (“the land itself vomiteth out her inhabitants”). Lev 19: the positive holiness-program with the sixteen-fold “I am the LORD” refrain and the neighbour-love command at its center. Lev 20: the same prohibitions in casuistic form (“If a man uncover the nakedness of… he shall surely be put to death”), with explicit penalties attached, ending with the second-person land-vomits warning (“that the land… spue you not out”). The triptych’s literary architecture is: negative prohibitions (Lev 18) / positive holiness program (Lev 19) / consequence-attaching penalties (Lev 20). The central Lev 19 is framed and protected by the prohibitions and penalties on either side. Standard critical commentary (Milgrom most explicitly) reads this as the Holiness Code’s most-deliberate single literary patterning; the central Lev 19’s positive program is the framework’s heart, with Lev 18 and 20 marking its boundaries.
The moth yumat / karet distinction and the rabbinic mitigation tradition. Leviticus 20’s two penalty-vocabularies are theologically distinct. Moth yumat (court-imposed death) presupposes a working judicial system, witnesses, and a community willing to enforce the penalty. Karet (divine cutting off) is for violations that no human court is positioned to address — typically because the violation occurs privately, between consenting parties, or in a context where no third-party complainant exists. The Mishnah’s later procedural restrictions on moth yumat cases (two valid witnesses required; immediate-prior formal warning required; the perpetrator must acknowledge the warning and proceed anyway; capital court convictions further restricted) made literal application of the chapter’s penalties extremely rare in practice. records the famous Mishnaic statement that a Sanhedrin that imposed death once in seven years was called destructive (R. Eleazar ben Azariah: once in seventy years). The chapter’s penalties are theologically operative as boundary-markers; halakhic practice largely sublimated them.
The cursing-parents penalty and the corban evasion. Leviticus 20:9’s “every one that curseth his father or his mother shall be surely put to death” is the OT’s strongest single statement of parental honour. The penalty’s severity reflects the Decalogue’s placement of parental honour at the hinge between the God-directed and neighbour-directed commandments (Exodus 20:12↗). Christ’s controversy with the Pharisees at Mark 7:9–13↗ turns directly on this verse: He cites Lev 20:9 alongside Exod 20:12 and accuses the Pharisees of nullifying the commandment by their corban tradition (declaring resources reserved for the temple and thereby legally unavailable for parental support). The chapter’s penalty becomes the textual basis for Christ’s most direct single charge of tradition-overriding-Torah. The verse’s severity is paralleled in Proverbs (Proverbs 20:20↗: “Whoso curseth his father or his mother, his lamp shall be put out in obscure darkness”; Proverbs 30:17↗: “The eye that mocketh at his father, and despiseth to obey his mother, the ravens of the valley shall pick it out”). The chapter at hand installs the legal-penalty form of this principle that runs across the OT wisdom and prophetic literature.
