EXODUS 20 — THE TEN WORDS: THE COVENANT'S FOUNDATIONS

The Ten Words (Exod 20:1–17; Deut 5:6–21; the OT calls them the ten words, ʿăśeret haddeḇārîm, Exod 34:28; Deut 4:13; 10:4) function as the covenant's constitution: everything in chapters 21–23 casuistically applies these ten principles, and the rest of the Pentateuch's ethics expands them. Their structure follows treaty-form: preamble (I am the LORD your God), historical prologue (who brought you out of the land of Egypt), stipulations (the ten), and sanctions (visiting iniquity... to the third and fourth generation; showing steadfast love to thousands). The Sabbath-command (20:8–11) grounds rest in creation (as in Gen 2:2–3) rather than in the manna — Deuteronomy 5:15 gives the alternate grounding in redemption; both are true, and the church has received the Sabbath's principle as the Lord's Day without inheriting the Mosaic penalty-structure. The people's terror-request (20:18–21) establishes mediated revelation as Israel's standing arrangement until the prophet-like-Moses (Deut 18:15–18) and, beyond him, the Son (Heb 1:1–2). And the altar-law (20:24–26) legislates the counter-intuitive simplicity of acceptable worship before any tabernacle is described: God specifies how he will be approached — by sacrifice on earth-altars, in every place where I cause my name to be remembered. The chapter is the Torah's constitutional summit: the Ten Words (20:1–17) spoken by God directly (20:1 — God spoke all these words, and 20:22's warning that Israel could not bear direct speech establishes the mediator-pattern that Moses' career institutionalizes). The Words' structure is two-table: the first four (or three, by another counting) address the Godward-relationship, the last six (or seven) the manward — and the hinge is the Sabbath-command, the only Word addressed to both tables' logic (Godward as imitation of the Creator's rest, manward as rest for the household). Israel's terror-response (20:18–21 — let not God speak to us, lest we die; you speak to us, and we will listen) is recorded without rebuke as a permanent datum: the holiness that terrified at Sinai was not a defect of the old covenant but its truth, and the new covenant's glory is precisely that the same holiness is now approached with confidence (Heb 4:16; 10:19–22) because the Mediator has borne what the mountain threatened.

Deuteronomy 5:6–21 — the Words restated: the decalogue's second giving Exodus 34:28 — the ten words written: the covenant's inscription Psalm 19:7–11 — the law of the LORD is perfect: the Words in worship Jeremiah 31:33 — I will write it on their hearts: the new covenant's promise Matthew 5:17–48 — not abolished but fulfilled: Jesus on the mountain Matthew 22:34–40 — love God and neighbor: the two tables' summary Romans 13:8–10 — love is the fulfilling of the law Hebrews 4:9–10 — the Sabbath-rest remains: the eighth-day hope "The Ten Commandments are commonplace ethics any people could invent." The apologetic value of the decalogue is not its uniqueness but its source and scope: the commands are given by the delivered-from one (I am the LORD your God, who brought you out), which grounds morality in history and person rather than in nature or utility; they span both tables (God and neighbor), which ancient Near Eastern law collections never do (they protect property and persons; they do not command exclusive worship of one God, Sabbath rest for slaves, or the governance of desire); and their tenth commandment legislates the heart, which no human court can enforce and no ancient law-code attempts. The second table resembles other codes because a just God writes his law on every conscience (Rom 2:14–15); the first table and the heart-reach distinguish this law as revelation, not reflection.
