Mishnah Middot 4:4-5

Sugya Map

• Core Issue: The structural geometry of the Hekhal and the ta'im (cells) surrounding it, specifically the migra'ot (recesses/ledges) that create the stepped-width profile of the chambers.
• Primary Sources: Mishnah Middot 4:4–5; I Kings 6:6; Ezekiel 41:23–24.
• Nafka Mina:
  • Does the Hekhal wall thickness remain constant, or is it tapered?
  • The architectural function of the mesibbah (winding staircase) and the spatial navigation of the Kohanim.
  • The halachic status of the "upper chamber" (aliyah) and the Holy of Holies regarding sanctity (kedushah) and human access.

Text Snapshot

Mishnah Middot 4:4:

"הַתַּחְתּוֹנָה חָמֵשׁ אַמּוֹת וְרֹבֶד שֵׁשׁ, הָאֶמְצָעִית שֵׁשׁ וְרֹבֶד שֵׁבַע, הָעֶלְיוֹנָה שֵׁבַע..." (The lowest [story] was five cubits wide and at the ceiling six cubits...)

Leshon Nuance: The term roved (רובד) is crucial here. While often translated as "ceiling," R’ Shemaiah (4:4:2) clarifies it as the tikrah (ceiling) whose beams embed into the migra'ot of the Hekhal wall. The linguistic shift from 5 to 6 to 7 denotes the inward stepping of the floor space as the wall thickness outwardly tapers, or conversely, as the beams find purchase in the wall. Note the dikduk in the Mishnah—it identifies the width at the floor and the width at the ceiling, creating an architectural trapezoid for each cell.

Readings

Rambam: The Geometric Expansion

Rambam (Comm. to Middot 4:4) argues that the ta'im (cells) were not merely rooms, but gazuztra'ot (balconies/surroundings) that grew wider as one ascended. His chiddush is teleological: the walls were built with migra'ot (recesses) specifically to ensure the upper stories did not "attach" to the main wall of the Hekhal in a way that would suggest structural reliance, or perhaps to maintain distinct structural integrity for each level. The widening from 5 to 6 to 7 cubits represents a deliberate architectural strategy to maintain stability while increasing space as the load-bearing requirements decreased toward the roof.

Tosafot Yom Tov: The Polemic of the Wall

The Tosafot Yom Tov (4:4:1) engages in a rigorous debate with the Rashi-Rashash school regarding the migra'ot. TYT asks: if the wall is 6 cubits thick (as Rashi suggests), how can we accommodate the structural logic of the mesibbah and the cells without the wall thinning to an unstable degree? He notes that if the mesibbah wall itself is subject to these migra'ot, the remaining space becomes absurdly narrow. His chiddush is a rejection of the "constant wall" theory; he posits that the migra'ot were not merely architectural "steps" but essential indentations that defined the thickness of the support beams themselves. He forces us to reconcile the I Kings 6:6 verse—"narrower without"—with the internal experience of the Kohen traversing the mesibbah.

R’ Shemaiah: The Functional Mechanics

R’ Shemaiah (4:4:2) provides a pragmatic engineering perspective. He explains the widening (5, 6, 7) not as a change in the room itself, but as a function of the beams (korot) entering the Hekhal wall. As the building rises, the beams sit one cubit deeper into the migra'ot (recesses) of the wall, thus the floor space of the cell above effectively "gains" a cubit of width relative to the one below. This is a brilliant reconciliation of the textual description with the physical reality of load-bearing masonry.

Friction

Kushya: The greatest friction arises from the "Lion" metaphor at the end of Middot 4:5: “The Hekhal was narrow behind and broad in front, resembling a lion.” How can the Hekhal be narrow behind (the West) and broad in front (the East) if the internal dimensions are fixed at 20 cubits, and the external walls are described as symmetric?

Terutz 1 (Structural): The width refers not to the internal Hekhal sanctuary space, but to the footprint of the entire complex, including the ta'im and the mesibbah. The tapering of the exterior walls (the migra'ot) creates a wider silhouette at the front (the porch/entrance) and a narrower footprint at the rear, mimicking the anatomical proportions of a lion.

Terutz 2 (Symbolic/Halachic): As the Tiferet Yisrael (Yachin 4:29:1) suggests, the "narrowness" is a structural necessity to prevent the ta'im from encroaching on the sanctity of the Hekhal itself. The narrowing behind is a visual marker of the transition from the "outer" space (accessible) to the "inner" space (the Holy of Holies), which is strictly demarcated. The "lion" is not just geometry; it is a boundary marker.

Intertext

• Ezekiel 41:23–24: The source of the dual doors. The Mishnah relies heavily on the Prophet’s vision to justify the structural reality of the Second Temple. Note how the Mishnah treats the Vision as a blueprint, not merely a prophecy.
• SA Hilchot Beit HaBechirah 4:10: Maimonides codifies the migra'ot as the defining feature of the Hekhal exterior. He moves from the aggadic description of the "lion" to the halachic requirement of the building's shape, demonstrating that the structural dimensions are an integral part of the Temple’s mitzvah of construction (binyan).

Psak/Practice

In meta-halachic terms, the Middot analysis teaches us the principle of "Tzurah" (Form) as a halachic requirement. A structure is not "The Temple" unless it adheres to these geometric specifications. If the migra'ot were built incorrectly, the Hekhal might be pasul (invalid). Practically, this instructs us that architectural precision is a form of avodah. The "trap doors" into the Holy of Holies, designed to prevent the workmen from "feasting their eyes," serves as a precedent for tzniut (modesty) in sacred spaces: accessibility must be mediated, and the human gaze must be restricted even when performing necessary maintenance.

Takeaway

The Hekhal is a masterclass in controlled expansion and restricted vision; it uses geometric tapering to safeguard the sanctity of the interior, proving that in the economy of holiness, architectural form is the primary guardian of function.
