Bible Study: 7th Commandment -- Do Not Commit Adultery (Exo 20:14)

Question

What does the Bible say about the seventh commandment? Trace the creation foundation of marriage (Gen 2:24 -- "one flesh," pre-Sinai). What does Leviticus 18 say about sexual ethics, and how does its introduction (Lev 18:24-30 -- the Canaanites judged for the same violations) establish the scope? How does Jesus deepen this to lust (Mat 5:27-28) and address divorce (Mat 19:3-9)? What do Paul (1 Cor 6:18-20; Rom 1:26-27), the author of Hebrews (13:4), and Revelation (21:8; 22:15) say? Examine: Gen 2:24, Exo 20:14, Lev 18:1-30, Mat 5:27-28, Mat 19:3-9, 1 Cor 6:18-20; 7:1-16, Rom 1:26-27, Heb 13:4, Rev 21:8; 22:15.

Key findings from existing studies: - law-12: The second antithesis (Mat 5:27-28) quotes Exo 20:14 verbatim and extends it to lustful intent -- deepening, not revoking. This is the "magnification" of Isa 42:21. - law-29: E15 explicitly lists "Thou shalt not commit adultery" among the Decalogue commands Paul quotes as continuing (Rom 13:8-10). James 2:11 treats the adultery prohibition alongside the murder prohibition as the "law of liberty" still operative. - pentateuch-sexual-legislation: Lev 18 covers 12+ categories of sexual sin. Lev 18:24-30 states these are the sins for which the Canaanites were judged, establishing that the sexual ethic is not uniquely Israelite but universally binding. - cmd-evidence.db: E393 (Jas 2:11) explicitly pairs the adultery and murder commandments. E031 (Rom 13:8-10) lists the 7th commandment as love's content. E380 (Jer 7:9-10) lists adultery alongside other Decalogue violations.

Focus Areas

  1. Creation foundation: Gen 2:24 establishes the "one flesh" marriage principle before Sinai. How does this pre-Sinai origin affect the commandment's scope? Jesus appeals to Gen 2:24 in Mat 19:4-6 as the creation baseline.

  2. Leviticus 18 comprehensive scope: The chapter addresses incest (6-18), adultery (20), homosexuality (22), bestiality (23), and states the Canaanites were expelled for these same violations (24-30). This establishes the sexual ethic as universal, not merely Israelite.

  3. Jesus' two-fold deepening: (a) Adultery extended to lustful intent (Mat 5:27-28); (b) Divorce restricted -- Moses allowed it "for the hardness of your hearts" but "from the beginning it was not so" (Mat 19:8). Jesus appeals to Gen 2:24 and tightens the standard.

  4. The porneia exception clause: Mat 19:9 -- "except it be for porneia" -- the scope and meaning of porneia (G4202) in this context.

  5. Paul's body-temple theology: 1 Cor 6:18-20 -- "your body is the temple of the Holy Ghost" -- the theological basis for sexual purity. Also 1 Cor 7:1-16 on marriage, celibacy, and the believing spouse.

  6. Romans 1:26-27: Paul's treatment of homosexual acts as "against nature" -- how this connects to the Lev 18 framework.

  7. Hebrews 13:4: "Marriage is honourable...but whoremongers and adulterers God will judge" -- the positive and negative sides.

  8. Eschatological exclusion: Rev 21:8 and 22:15 -- pornos (fornicators/whoremongers) excluded from the new Jerusalem.

  9. Figurative dimension: Adultery/whoredom as metaphor for idolatry (Jer 3:2; Ezk 16; Hos 1; Rev 17) -- spiritual unfaithfulness.

  10. Pre-Sinai evidence: Gen 20:3 (Abimelech warned), Gen 26:10-11 (Abimelech recognized guilt), Gen 38:24 (Judah's sentence on Tamar), Gen 39:9 (Joseph: "sin against God") -- the moral awareness before Sinai.
