Exodus 27 — The Altar of the Courtyard and the Enclosure of the Sanctuary

Meaning

Exodus 27 belongs to the heart of the priestly block of the Torah devoted to the construction instructions for the mishkàn (הַמִּשְׁכָּן, the Dwelling-Tabernacle) and unfolds in three units: vv. 1-8 describe the altar of burnt offerings, vv. 9-19 trace the perimeter of the courtyard, vv. 20-21 — with which the Parashat Tetzaveh begins — prescribe the oil for the perpetual lamp. The movement of the chapter proceeds from the exterior toward the service: first the place of sacrifice, then the boundary of the sacred, finally the light that never goes out.

The mizbèach (מִזְבֵּחַ) derives from the root zbch, to slaughter-to offer: not a mere hearth, but the theological place where blood mediates between the human world and the divine presence. The form is normative: ravuà' yihyèh (רָבוּעַ יִהְיֶה), «square it shall be» — in the cosmology of the ancient Near East the square expresses the completeness of the four cardinal points, the totality of space oriented toward the sacred center. The qarnotàv (קַרְנֹתָיו), the horns on the four corners, concentrate the sacrificial force — qèren (קֶרֶן) denotes power and sovereignty — and are the point where blood is applied in the expiatory rites (cf. Lev 4:7.18.25.30). The detail mimmènnu (מִמֶּנּוּ), «of itself», establishes that the horns are intrinsic to the structure, not applied: the expiatory power is not an accessory of the altar, it is its very substance.

The dominant metal is nechòshet (נְחֹשֶׁת, copper-bronze): in the metallic hierarchy of the mishkàn — gold in the most sacred area, silver in the intermediate zones, copper on the outside — it signals the space of judgment-purification, where sin is burned and the ash (dèshen) attests the consumed sacrifice. The altar is navuv luchòt (נְבוּב לֻחֹת), hollow and made of boards: a transportable structure, suited to the wilderness wandering, filled with earth at each halt according to the Tannaitic tradition (Mekhilta de-Rabbi Ishmael, Yitro), which thus harmonizes the altar of planks with the precept of the «altar of earth» of Ex 20:24. The model is not a human invention: ka'ashèr her'àh otkhà ba-hàr, «as you were shown on the mountain» (v. 8) — the archetype revealed at Sinai precedes and norms the execution.

The chatzèr (חָצֵר, courtyard) is the zone of transition between the profane and the presence of Elohim: the hangings of shèsh moshzàr (שֵׁשׁ מָשְׁזָר, twisted linen) create a visual and sacral boundary — the world may glimpse the structure, not penetrate it freely. The masàkh (מָסָךְ) of the eastern gateway, in the four colors — tekhèlet (blue-violet of the murex), argamàn (red purple), tola'at shanì (crimson of the kermes), twisted linen — announces the passage toward the sacred with the chromatic language reserved for the inner spaces. Vv. 20-21 finally shift the focus from the architecture to the perpetual service: ve-attàh tetzavvèh (וְאַתָּה תְּצַוֶּה), «and you shall command» — Moses the active intermediary of the divine transmission — that the children of Israel bring shèmen zàyit zakh katìt (שֶׁמֶן זַיִת זָךְ כָּתִית), pure beaten olive oil, to make the flame rise tamìd (תָּמִיד), from evening to morning, before the Tetragrammaton: «a perpetual statute» (chuqqàt olàm) for all generations.

Why it differs from current translations

Several choices of the current versions flatten theologically decisive nuances of the Masoretic text, and in this chapter the LXX presents notable structural divergences.

Nechòshet: rendered uniformly «bronze», but the Hebrew term denotes copper and its alloys (including bronze). The distinction is not merely metallurgical: in cultic symbolism copper is the metal of the boundary and of judgment, contrasted with silver (redemption) and gold (divine glory). Writing generically «bronze» dissolves the coherence of the hierarchical system of metals.

Ravuà' yihyèh: often rendered «of square form», but the yiqtol has prescriptive value — «it shall be square» — a sacral requirement, not a descriptive note. Likewise mimmènnu (v. 2), the horns «of itself», that is, structural, disappears in many renderings; the LXX (ex autoû) here correctly preserves the datum.

The furnishings of v. 3: the MT opens with the vessels for the ashes (sirotàv le-dashnò, from the root of dèshen, fat-ash); the LXX instead reads a perimeter rim (stephánēn) and a cover (kalyptêra), items without Masoretic correspondence, and lists the utensils differently (flesh-hooks, brazier).

Karkòv (v. 5): a hapax of the MT, a rim or projecting ledge; the LXX reads hypò tḕn escháran, «under the grate», and refers to the rings what the MT refers to the net. The versions that translate «rim», «base» or «grating» in fact choose between two divergent textual traditions, rarely signaling it.

The cardinal points: at v. 11 the MT reads tsafòn (north) where the LXX has pròs apēliṓtēn, «toward the east wind»; at v. 13 the MT has qedmàh mizrèachah, «toward the east, the rising sun», where the LXX reads pròs nóton, «toward the south». The exchange of the cardinal labels reveals an autonomous Greek transmission of the topographical scheme of the courtyard.

Pluses of the LXX: the acacia (atzé shittìm) becomes in Greek «incorruptible wood» (asḗptōn): the matter of the cult is reread within the Hellenistic category of incorruptibility, foreign to the material realism of the MT. At v. 11 the LXX adds that the bases were «overlaid with silver» (periērgyrōménai argýrō), a plus absent in the MT, which for the bases gives only «twenty of copper»; at v. 13 it adds columns and bases that the MT does not list.

Layered receptions

The Jewish reception of the chapter is first of all halakhic. The Mishnah devotes a systematic treatment to the altar: Middot 3:1 describes the altar of the Second Temple — a base of thirty-two cubits by thirty-two, with horns of one cubit — showing how the Mosaic measure of five cubits was enlarged in the history of the cult while preserving the requirement of the square. Zevachim 5 (the mishnah Eizehu meqomàn, which entered the daily liturgy) codifies where to apply the blood of the various offerings: for the sin offering, on the four horns. Tamid 1:2 opens the priestly day with the terumàt ha-dèshen, the removal of the ash — perpetual execution of what Ex 27:3 prepares with the «vessels for the ashes». For the lamp, the Tannaitic tradition grades the oil: only the first, zakh katìt, is fit for the menorah — «beaten for the luminary, not beaten for the meal offerings» (Mishnah Menachot 8:4; cf. b. Menachot 86b) — while b. Shabbat 22b reads in the perpetual flame «a testimony to those who come into the world that the Shekhinah dwells in Israel». The Targum Onkelos stabilizes the synagogal reading by rendering with technical Aramaic vocabulary the hangings, bases and hooks of the courtyard.

The Christian reception proceeds by typology. The epistle to the Hebrews reads the earthly sanctuary as «a copy and shadow of the heavenly realities» (Heb 8:5), recalling precisely the principle of Ex 27:8 — «as you were shown on the mountain» — and claims: «we have an altar» (Heb 13:10). Revelation sees under the altar the souls of the slain witnesses (Rev 6:9), transferring to martyrdom the imagery of the outer altar where the blood touches the base. The perpetual lamp feeds the christology of the light (Jn 8:12) and the exhortation to the lit lamps (Lk 12:35). In a non-supersessionist reading this typology is fulfillment, not substitution: the NT presupposes the perennial significance of the Israelite institution — the archetype shown on the mountain remains the common reference of the two traditions, which each read in it their own way of access to the God of Israel.

Historical reconstruction (aggadah)

The material background of the chapter is well rooted in the ancient Near East. Quadrangular altars with horns at the corners are archaeologically attested in the land of Israel (the stone exemplars of Beer Sheva and Megiddo), and the metallurgy of copper flourishes in the Aravah from the Bronze Age onward: the nechòshet of the altar belongs to the technical culture of the region. The dismountable structure too — boards, hangings stretched over columns with bases, poles for transport — reflects the technology of the portable pavilions of the Egyptian New Kingdom, consistent with an itinerant cult in the wilderness. The courtyard of a hundred cubits by fifty delimits a rectangle in a 2:1 proportion whose axis runs from east (entrance) to west (Holy of Holies): whoever enters turns his back on the rising sun — an implicit polemic against the solar cults (cf. Ezek 8:16).

The Tannaitic aggadah addresses the tension between the two altars of the Torah: the one «of earth» of Ex 20:24 and the one «hollow, of boards» of Ex 27:8. The Mekhilta de-Rabbi Ishmael (Yitro) resolves it: the wooden altar overlaid with copper was filled with earth at each encampment — the transportable case is the container, the earth the true sacrificial surface, so that every burnt offering in the wilderness remains offered «on an altar of earth». In the same context the Tannaitic tradition on the prohibition of iron near the altar (cf. Ex 20:25) contrasts the metal that shortens the life of man with the altar that prolongs it: the copper of the altar consumes sin, while the iron of the sword cannot touch what makes peace between Israel and heaven. In the synagogal cycle vv. 20-21 open the Parashat Tetzaveh, read in the weeks that prepare for Purim (with the Shabbat Zakhor when it coincides): the perpetual light is thus juxtaposed, in the liturgical year, to the memory of the deliverance from the plan of extermination.

Practical observance

When the Torah is normative, Exodus 27 generates concrete practices. The explicit mitzvah of vv. 20-21 has two sides: the people bring the oil — ve-yiqchù elèkha, «let them take for you», a command addressed to all Israel — and the priests set up the lamp from evening to morning. The oil must be zakh katìt: the Tannaitic halakhah grades the qualities and reserves for the luminary only the first drop of the beaten olive (Mishnah Menachot 8:4), and the baraita prescribes to kindle «until the flame rises by itself» (b. Shabbat 21a): the observant does not produce the light, he makes it capable of standing on its own. After the destruction of the Temple this praxis survives in ritual memory: the ner tamìd that burns before the ark in every synagogue, and the care of the light as a liturgical gesture (the lamps of Shabbat and of Chanukkah inherit its grammar). The Talmud moreover links the schedule of the daily prayers to the perpetual rhythm of the cult (b. Berakhot 26b): to pray at fixed times is the post-sacrificial way of guarding the tamìd.

Where the praxis finds documented continuity in the NT, the connection is precise. The lamp that does not go out has its correlate in the command of Spiritual Vigilance: «let your loins be girded and your lamps lit» (Lk 12:35) — concretely, to keep the inner life fueled at fixed hours, with regular prayer and daily examination, like the priest who every evening refills the menorah with oil. The rhythm me-èrev ad-bòqer extends into the categories of Praying and of Praise and Adoration: prayer «without ceasing» (1Thess 5:17) and the liturgy of the hours carry out in time what the oil carried out in the flame — continuity, not episodicity. The orderly arrangement of the service — Aaron and his sons who set up the lamp according to statute — finds an echo in Order in Worship: «let everything be done decently and in order» (1Cor 14:40); whoever serves in the assembly prepares, arranges and guards with the same material care prescribed for the hangings and the vessels of the courtyard. The square of the altar and the enclosure of the courtyard, architectural in themselves, do not generate direct mitzvot: the tradition has derived from them the discipline of the boundaries of the sacred — approaching the cult by degrees and with preparation — rather than a specific gesture.
