The Ten Words and the Theophany of Sinai — Ex 20:1-26

Meaning

Exodus 20:1-26 constitutes the theological-juridical core of the Torah and the heart of the Sinaitic revelation. The text never speaks of «ten commandments»: the opening reads «And Elohìm spoke all these Words» — the MT has אֱלֹהִים Elohìm, which the LXX renders with κύριος — and the Jewish tradition calls the passage aséret ha-dibròt, «the ten Words». The distinction is not merely terminological: davàr fuses in the Hebrew lexicon word, event and thing. The dibròt are not articles of a code promulgated in a neutral imperative mode; they are speech-acts that constitute the people in their identity before the divine.

In the Jewish reckoning the first Word is already verse 2: Anokhì — an archaic and emphatic form of the first person, weighted with majesty — «I am the Tetragrammaton your God, who brought you out of the land of Egypt, out of a house of bondage» (bet avadìm, a technical locution that defines the prior servile status in Egypt). The choice is hermeneutically decisive: the Law is born from liberation, not the reverse. The Tetragrammaton does not present itself as an abstract legislator but as the God who has already acted in history, who has already broken the chains; the decalogue is not the condition of salvation but the response to a salvation already wrought. The Mekhilta de-Rabbi Ishmael (Bachodesh 5) comments on the self-presentation by observing that the same God appeared at the sea as a warrior and at Sinai as an elder full of mercy: the divine uniqueness asserts itself through history, not through speculation. A Talmudic tradition (b. Makkot 24a) further recalls that the first two Words — Anokhì and «You shall have no other gods» — Israel heard «from the mouth of the Power» itself, without the mediation of Moses: for this reason they are formulated in the first person, whereas from the third Word onward the text speaks of the Tetragrammaton in the third person.

The theophany that frames the proclamation (vv. 18-21) is described with a deliberate synesthesia: the people «saw the voices» (ro'ìm et ha-qolòt), amid thunder, flames, the sound of the shofàr and the smoking mountain. Terrified, the people draw back and ask for Moses' mediation; Moses instead advances toward the arafèl, the dense darkness where the divine dwells — a paradoxical obscurity that will become a topos of Jewish mysticism and of apophatic theology. The concluding section (vv. 22-26) is not an appendix but immediate halakhah: before any elaborate cult, the Tetragrammaton prescribes an altar of earth (mizbàch adamàh) or of whole stones untouched by iron — the instrument of war that shortens life must not touch the altar that prolongs it — and without steps, so as not to expose the nakedness of the one who ascends. The worship of the liberating God must be sober, physically discreet, rooted in matter untransformed by human hands.

Why it differs from current translations

The first divergence concerns the reckoning of the Words. The Jewish tradition counts the prologue (v. 2) as the first autonomous Word; the Catholic-Lutheran and Reformed numberings treat it as a preamble and redistribute differently the prohibition of other gods and that of images. The Hebrew-first translation lets the structure of the MT emerge without imposing any confessional numbering.

The sabbath preserves a double recension: Ex 20:8 has zakhòr («remember», μνήσθητι), while the parallel of Deut 5:12 has shamòr («observe»). Current versions harmonize by choosing one or the other, losing the tension; the tannaitic tradition resolves it without dissolving it: «zakhòr and shamòr were said in a single utterance» (Mekhilta de-Rabbi Ishmael, Bachodesh 7) — inner memory and outer observance are simultaneous, not alternatives.

«You shall not kill» flattens lo tirtzàch: the root ratzàch designates specifically unlawful killing — intentional homicide or that by grave negligence — not haràg («to kill» in a neutral sense) nor hemìt («to put to death»); the distinction is juridically decisive, because the text does not forbid every form of killing but the crime. Analogously «you shall not steal» (lo tignòv) is read by the Talmudic tradition as the prohibition of stealing a person, kidnapping (b. Sanhedrin 86a): in the immediate context of capital offenses — homicide, adultery — even the theft named here is the one that touches life, while the theft of goods is regulated elsewhere.

At v. 3 the MT has al panài (עַל פָּנָי), «before my face»: the other gods are excluded from the very presence of the Tetragrammaton, not simply «apart from me» (πλὴν ἐμοῦ) as the LXX attenuates. At v. 7 la-shàw («in vain») covers the entire spectrum of nullity: perjury, magical-instrumental use of the Name, false prophecy. The order of vv. 13-15 also diverges: the MT has homicide-adultery-theft, the LXX adultery-theft-homicide. Finally at v. 12 the LXX adds «that it may be well with you» (ἵνα εὖ σοι γένηται) and qualifies the land as «good» (ἀγαθῆς): pluses absent from the MT but taken up literally in Eph 6:2-3.

Layered receptions

In the Jewish reception the ten Words at first had a precise liturgical place: the Mishnah (Tamid 5:1) attests that the priests in the Temple recited them every day together with the Shema. Outside the Temple, however, the practice was abolished «because of the claims of the minim» (b. Berakhot 12a): to prevent the heretics from saying that only the ten Words — and not the entire Torah — had been given at Sinai. The liturgical renunciation thus safeguards a hermeneutical principle: the decalogue is not a canon within the canon, but the synthesis of an indivisible Torah. From zakhòr the tradition further derived the active and positive remembrance of the sabbath — «remember it over the wine» (Mekhilta, Bachodesh 7) — the root of the verbal sanctification of the day, while from shamòr derive the abstentions.

The Christian reception presupposes the decalogue as an obvious and shared patrimony: Jesus lists it to the rich young man (Mk 10:19) and in the Sermon on the Mount radicalizes it — «you have heard that it was said... but I say to you» (Mt 5:21-37) — carrying lo tirtzàch as far as anger and lo tin'àf as far as the gaze. It is the logic of fulfillment, not of abrogation: «I have not come to abolish but to fulfill» (Mt 5:17), in the same movement by which the masters of Israel built protective fences around the Torah. Paul sums up the second tablet in love of neighbor (Rom 13:8-10), and Eph 6:2-3 cites the command to honor parents according to the LXX, calling it «the first commandment with a promise». Heb 12:18-21 rereads the theophany — the fire, the darkness, the storm, the sound of the trumpet — as a term of comparison, not of contempt: Sinai remains the place where God has spoken. Fulfillment, not substitution: the Sinaitic covenant is not revoked by the NT, which cites it as a living word.

Historical reconstruction (aggadah)

The form of the chapter reflects the formulary of the treaties of the ancient Near East: self-presentation of the sovereign, historical prologue that grounds loyalty, clauses of fidelity. But the decalogue overturns the imperial practice: the sovereign who speaks does not claim tributes, he recalls a liberation («I brought you out»); and the recipients of the clauses are not vassal kings but an entire people — including the son and the daughter, the manservant and the maidservant, the cattle and the ger, the resident alien included in the sabbath rest with a precise social import. The prohibition of images, with the reference to «what is in the heavens above», strikes the astral cult well documented in prophetic polemic: in a world where every power was represented by statues and simulacra, a God without image, recognizable only by his liberating action, is a revolutionary anomaly.

The aggadah measures the event on the body of Israel: «at every Word that issued from the mouth of the Holy One, blessed be he, the soul of Israel departed... and with the dew with which he will revive the dead he revived them» (b. Shabbat 88b). The same Talmudic page narrates the angels' objection to the delivery of the Torah to a mortal, when Moses ascended on high; and Moses answers by citing the Words themselves: did you perhaps go down to Egypt? Were you slaves? Have you father and mother among you? The Torah is for those who live in history, in toil and in temptation, not for the celestial ministers. On «seeing the voices» the Mekhilta (Bachodesh 9) reads the paradox literally: at Sinai Israel «saw what is ordinarily heard» — the experience exceeds the ordinary sensory categories. Targum Onkelos soberly maintains the datum of the text: the people «saw» the thunders. Rashi, following the tannaitic tradition, notes that zakhòr and shamòr were pronounced «in a single word», which a human mouth cannot say nor a human ear hear.

Practical observance

The ten Words are operative mitzvot, not abstract principles. The sabbath is observed with a double movement: from zakhòr the active remembrance — the tannaitic tradition prescribes «remember it over the wine» (Mekhilta, Bachodesh 7), the verbal sanctification of the day at its entry — and from shamòr the abstention from work, extended by the text itself to sons, servants, cattle and the ger: rest is a social act, not an individual privilege. The honoring of parents (kibbud av va-em) is defined by the Talmudic tradition in concrete gestures: to give them food and drink, to clothe them, to accompany them (b. Kiddushin 31b). The safeguarding of the Name requires not to swear falsely nor in vain, not to instrumentalize the sacred for magical or fraudulent ends. The halakhah of the altar (vv. 24-26) trains in cultic sobriety: simple matter, no iron, no ostentation of the body of the one who ascends.

Where the praxis finds documented continuity in the NT, the link is explicit. The command to honor parents continues in the Duties of Children: Eph 6:1-3 cites Ex 20:12 according to the LXX («that it may be well with you»), and Mk 7:10-13 defends the command against the practice of qorban that emptied it of substance — concretely: to provide materially for parents, not only to respect them in words. The prohibition of other gods and of images continues in the Prohibitions of Idolatry: «flee idolatry» (1 Cor 10:14), «keep yourselves from idols» (1 Jn 5:21) — concretely: not to take part in any idolatrous cult nor in its banquets. The prohibition of the Name in vain continues in the Prohibitions in Communication: «do not swear at all... let your yes be yes» (Mt 5:33-37; Jas 5:12) — the reliable word that makes the oath superfluous is the evangelical fence around la-shàw. The «you shall not kill» continues in the Prohibitions of Anger and Conflict (Mt 5:21-22: the safeguarding begins with anger and insult) and the «you shall not commit adultery» in the Sexual Prohibitions (Mt 5:27-28: the safeguarding of the gaze). As for the sabbath, the NT discusses its halakhah from within — «the sabbath was made for man» (Mk 2:27) — continuity of rabbinic discussion, not abolition of the day.
