Decalogue
The Decalogue is the ten-word covenant-text Yahweh himself spoke at Sinai, wrote with his own finger on two stone tables, and committed to Moses for the covenant people. Scripture exhibits it as a single divine utterance — "the words of the covenant, the ten commandments" (Ex 34:28) — both spoken from the fire on the assembly-day and inscribed on the tables that were lodged inside the ark of the covenant. Across the canon the ten words function as the head-charter of Yahweh's covenant with Israel, the standard summed up in love of God and of fellow man, and the law whose breaking in any single point is breaking of the whole.
The Sinai Speaking
The decalogue opens not as a code among codes but as a speech from God himself. Exodus heads the chapter with a speech-formula assigning every following command to one divine speaker: "And [the Speech of] God spoke all these words, saying" (Ex 20:1). The opening word of the ten — placed before any other clause — is the no-rival-god command in first-person divine voice: "You will have no other gods before me" (Ex 20:3; cf. De 5:7). The first table runs from the no-other-gods clause through the no-image, no-vain-name, and Sabbath commands (Ex 20:3-11; De 5:7-15); the second table covers honoring of father and mother, no killing, no adultery, no stealing, no false witness, and no coveting (Ex 20:12-17; De 5:16-21).
Two features fix the corpus as Yahweh's own. First, the prologue identifies the speaker as the exodus-deity: "I am Yahweh your God, who brought you out of the land of Egypt, out of the house of slaves" (Ex 20:2; De 5:6), so every clause that follows is heard against the exodus-deliverance. Second, the corpus closes by being summed under the title "the ten commandments" (Ex 34:28) — a designation Deuteronomy repeats when Moses recalls Yahweh's Horeb-speech: "And he declared to you⁺ his covenant, which he commanded you⁺ to perform, even the ten commandments; and he wrote them on two tables of stone" (De 4:13). The ten words and the covenant are exhibited as the same content under two names.
The Two Tables of Testimony
The tables are exhibited as a double-divine artifact: God-made tablet bearing God-made inscription. At the close of the Sinai-communing Yahweh hands Moses "the two tables of the testimony, tables of stone, written with the finger of God" (Ex 31:18). When Moses turns and descends, the tables are "written on both their sides; on the one side and on the other they were written" (Ex 32:15), and the narrator insists on the artifact's full divine origin: "And the tables were the work of God, and the writing was the writing of God, engraved on the tables" (Ex 32:16). The tables that come down the mount are not Moses' draft — they are Yahweh's own writing.
When Moses breaks the first set, Yahweh's covenant-renewal restores the same content on a new artifact. The command is to re-cut: "Cut for yourself two tables of stone like the first ones: and I will write on the tables the words that were on the first tables, which you broke" (Ex 34:1). After forty days and nights with Yahweh, "he wrote on the tables the words of the covenant, the ten commandments" (Ex 34:28). Deuteronomy's retelling adds a deposit-clause: Moses cuts the second tables, ascends, receives them as "according to the first writing, the ten commandments, which [the Speech of] Yahweh spoke to you⁺ in the mount out of the midst of the fire in the day of the assembly" (De 10:4), descends, and lodges them in the ark "as [the Speech of] Yahweh commanded me" (De 10:5).
The tables remain exhibited as the surviving covenant-witness centuries later. At Solomon's temple-dedication the chronicler insists on the ark's exclusive contents: "There was nothing in the ark but the two tables of stone which Moses put there at Horeb, by which Yahweh made a covenant with the sons of Israel, when they came out of the land of Egypt" (1Ki 8:9). Hebrews lists them among the covenant-memorials of the wilderness sanctuary alongside the manna-pot and Aaron's rod: "the tables of the covenant" (He 9:4). The same stone-witness that Moses brought down at Sinai is the stone-witness lodged in Solomon's oracle and remembered by the New Testament writer.
The Stone-Inscribed Law at Ebal
The stone-tables tradition is extended publicly at the conquest. Joshua, at the Ebal altar, inscribes a stone copy of the Mosaic law in the presence of the assembled people: "he wrote there on the stones a copy of the law of Moses, which he wrote, in the presence of the sons of Israel" (Jos 8:32). The act gathers the Mosaic law-text — the corpus carrying the ten words — into a publicly stone-engraved monument, with the people gathered half-by-half before mount Gerizim and mount Ebal as Moses had commanded (Jos 8:33). The stone-inscription mode that began on Sinai is repeated on the conquest-day as a public witness.
The Ten Words and the Two Loves
The New Testament reads the second-table commandments as fulfilled in love of fellow man. Paul rehearses them by name and gives the summary: "For this, You will not commit adultery, You will not kill, You will not steal, You will not covet, and if there be any other commandment, it is summed up in this word, namely, You will love your fellow man as yourself" (Ro 13:9). The conclusion: "love therefore is the fulfillment of the law" (Ro 13:10). The same double-summary is on the lawyer's lips in Luke: "You will love Yahweh your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your fellow man as yourself" (Lu 10:27), and Jesus accepts the answer as right.
James reads the tables as an indivisible whole. Citing two of the second-table prohibitions side by side — "Do not commit adultery" and "Do not kill" — he insists that the Lawgiver who said the one said also the other, so transgression of one is transgression of the law as such: "For whoever will keep the whole law, and yet stumble in one [point], he has become guilty of all" (Jas 2:10-11). The ten words stand, in James's reading, as one corpus under one speaker.
The Decalogue as Covenant-Charter
What ties the strands together is that the decalogue is exhibited as a covenant-text rather than a list. Yahweh's own designation at Sinai is "the words of the covenant" (Ex 34:28); Moses' rehearsal at Horeb names the same corpus "his covenant, which he commanded you⁺ to perform, even the ten commandments" (De 4:13); the ark inside which the tables lie is "the ark of the covenant" (He 9:4); and the Sinai-stones in Solomon's oracle are remembered as the artifact "by which Yahweh made a covenant with the sons of Israel, when they came out of the land of Egypt" (1Ki 8:9). The ten words are not exhibited as a self-standing moral code but as the written content of the Covenant itself — Yahweh-spoken, finger-of-God-written, ark-deposited, and in the New Testament summed up in the love-command that fulfills the law.
