Mishnah Middot 4:4-5

Sugya Map

• Core Issue: The structural geometry of the Second Temple (Beit HaMikdash), specifically the reconciliation of the ta’im (cells) dimensions with the magra’ot (setbacks) in the walls.
• Nafka Mina: Whether the magra’ot are carved into the Hekhal wall itself or exist as a structural feature of the cells, impacting the total width measurements and the architectural integrity of the "lion" shape (tzar me-achor v’rachav me-lifnim).
• Primary Sources: Mishnah Middot 4:4-5; I Kings 6:6; Ezekiel 41:23-24; Rambam, Hilchot Beit HaBechirah 4:3-4; Rashi/Rashash ad loc.

Text Snapshot

Mishnah Middot 4:4: "התחתונה ה' ורובד ו' ... [The lowest story] was five cubits wide and at the ceiling six cubits."

• Leshon Nuance: The term rovad (רובד) usually implies a layer or row, but here specifically denotes the ceiling or the "resting" point of the beams. The progression—5, 6, 7 cubits—reflects the magra’ot (setbacks) in the wall of the Hekhal. Note the dikduk in Yachin (4:29): the shift isn't merely aesthetic; it is structural, ensuring the cells do not "attach" (adhere) to the sacred wall of the Hekhal.

Readings

Rambam (Hilchot Beit HaBechirah 4:3)

Rambam posits that the magra’ot were necessary to ensure the cells remained distinct structures. He views the three stories as external galleries (gazoztra’ot) surrounding the Hekhal. His chiddush is that the wall thickness diminishes as one ascends, creating a "stair-step" effect. This prevents the upper stories from resting directly upon the lower ones, which would necessitate deeper penetration into the Hekhal’s sacred wall. By widening the interior space of the cell as it rises, he accounts for the 5-6-7 progression as a deliberate architectural defiance of weight-bearing reliance on the Hekhal’s primary structure.

Tosafot Yom Tov (on Middot 4:4)

The TYT engages in a rigorous debate with Rashi regarding the magra’ot. Rashi asserts that the cells themselves possessed the setbacks. The TYT pushes back, noting the physical impossibility if the wall thickness is constant. He suggests that the magra’ot are carved directly into the Hekhal’s wall (which he assumes is six cubits thick). His chiddush is a spatial analysis: the beams of the ceiling (the rovad) penetrate the wall at different depths. He challenges the reader to visualize the wall not as a solid block but as a graduated shelf, allowing the upper cells to be wider precisely because they "consume" less of the Hekhal’s wall-depth than the lower ones.

Friction

The Kushya: The Mishnah claims the Hekhal was "narrow behind and broad in front" like a lion. However, the measurements provided for the cells and the mesibbah (winding walkway) seem to imply a uniform expansion or a rigid grid. If the Hekhal is 100 cubits long and 70 wide (inclusive of cells), how does the "lion" geometry—the tzar me-achor (narrow rear)—reconcile with the standard cubit counts?

The Terutz: The Rashash offers the most precise resolution. He argues that the internal dimensions are not merely a flat footprint but a result of the mesibbah and the storage of knives (Beit HaMa’achalot). The "lion" shape is a product of the external profile; the tapering is not necessarily a failure of the interior room's integrity but a result of the thickening of the walls as one moves toward the Holy of Holies. The "narrowness" at the rear is a function of the increased wall mass required to support the massive structure of the Dvir (Holy of Holies), effectively "pinching" the outer boundary while the interior sanctuary remains a constant rectangle.

Intertext

• I Kings 6:6: "The lowest story was five cubits wide, the middle one six cubits wide, and the third seven cubits wide." The Mishnah is effectively an exegesis of this verse. The Gemara in Zevachim 54b discusses the Heichal layout, noting that the magra’ot were a chukah (statute) of the building’s sanctity, preventing the "unholy" cells from being structurally joined to the Hekhal—a conceptual parallel to the prohibition of ta’aruvot (mixtures) in sacrificial offerings.
• Ezekiel 41:23-24: The Mishnah’s reliance on these verses for the door measurements highlights a meta-halachic principle: the Temple’s physical dimensions are as much a subject of midrash as they are of architecture. The "two turning leaves" (dlatot that fold) are treated as a halacha l’Moshe mi-Sinai regarding the function of sacred space.

Psak/Practice

The Middot of the Temple are not merely historical records; they define the Shiurim (measurements) of sanctity. In contemporary meta-psak, these measurements serve as the archetype for Mikdash Me’at (the synagogue). The principle that the "holy" must not be structurally burdened by the "secular" (the cells/utility areas) is the basis for the halachic requirement that a synagogue must have distinct, unshared walls if it abuts a non-sacred structure. The "lion" shape serves as a reminder that architectural design must prioritize the Dvir (the center of sanctity) above all other structural concerns.

Takeaway

The Temple’s geometry is a testament to Hivdalut (separation); the magra’ot prove that sanctity is maintained not by walls alone, but by the intentional "stepping back" of secondary structures to allow the primary space to remain sovereign.
