Mishneh Torah, The Chosen Temple 2-4
Sugya Map
The architectural coordinates and vessel specifications of the Beit HaBechirah (The Chosen Temple) represent far more than historical blueprints; they constitute the ontological framework of the divine-human encounter in Halachah. Our sugya maps three distinct, highly integrated architectural and ritual systems: the absolute localization of the Altar (Makom HaMizbe'ach), the material plasticity of the Temple vessels (Klei HaMikdash), and the spatial-legal evolution of the Temple chambers (Heichal and Kodesh HaKodashim).
The primary issues, practical outcomes (nafka minas), and foundational sources of this sugya are structured as follows:

The Altar's Absolute Site (Kedushat Makom HaMizbe'ach)
- Core Issue: Is the holiness of the Altar’s site an inherent, untranslatable metaphysical reality (Kedushat Makom), or is it a functional designation generated by the physical Altar itself (Kedushat Mizbe'ach)?
- Primary Sources: Zevachim 62a, II Chronicles 3:1, Genesis 22:2.
- Nafka Mina: The halachic validity of offering sacrifices on the Temple Mount today without a standing Temple building (Makrivin a'p she'ein bayit). If the site's sanctity is absolute and independent, the obligation and capability to offer sacrifices persist even in a state of physical ruin.
Material Plasticity of Temple Vessels (Klei Shareit)
- Core Issue: Does a change in material (e.g., from gold to other metals) alter the essential identity (cheftza) of the vessel, or does it merely scale down its aesthetic execution (hiddur)?
- Primary Sources: Menachot 28a-28b, Exodus 25:31-40, Exodus 30:1-3.
- Nafka Mina: The halachic requirement of specific ornamental elements—such as the goblets, bulbs, and flowers (gevi'im, kaftorim, u'ferachim) of the Menorah—when crafted from non-noble metals under conditions of communal poverty.
Spatial Evolution and the "Dilemma of the Cubit" (Ama Teraxin)
- Core Issue: How does the halachic system resolve physical and architectural doubts (sfeika d'balka) concerning boundaries of differing sanctities (the Heichal versus the Kodesh HaKodashim)?
- Primary Sources: Yoma 51b-52b, Bava Batra 3a-3b, Mishnah Middot 4:7.
- Nafka Mina: The requirement to hang two curtains (parochot) instead of building a solid wall in the Second Temple, and the resulting legal status of the intermediate space (Ama Teraxin) during the High Priest's Yom Kippur service.

The Altar's Spatial Matrix
In Chapter 2, Halachah 7-8, the Rambam outlines the dimensions of the Altar:
"חֲמֵשֶׁת טְפָחִים עָלָה וַחֲמֵשֶׁת טְפָחִים כָּנַס--זֶה הוּא הַיְסוֹד... שְׁלֹשִׁים טֶפַח עָלָה וַחֲמֵשֶׁת טְפָחִים כָּנַס--זֶה הוּא הַסּוֹבֵב... עֲלֵה שְׁמוֹנָה עָשָׂר טֶפַח... אֵלּוּ הֵן הַקְּרָנוֹת... נִמְצָא גֹּבַהּ כָּל הַמִּזְבֵּחַ שְׁמוֹנָה וַחֲמִשִּׁים טֶפַח."[^1]
Philological Analysis
Observe the transition in units of measure. The Rambam switches between "cubits" (amot) and "handbreadths" (tefachim). The underlying talmudic discussion in Middot 3:1 notes that the Altar was measured using two distinct cubit scales: a five-handbreadth cubit (ama bat chamisha) for certain vertical dimensions, and a six-handbreadth cubit (ama bat shisha) for horizontal dimensions and other vertical coordinates.
By calculating the height in raw handbreadths (58 tefachim), the Rambam avoids semantic confusion. This total of 58 handbreadths is composed of:
- The base (yesod): 1 cubit of 5 handbreadths = 5 tefachim.
- The body up to the ledge (sovev): 5 cubits of 6 handbreadths = 30 tefachim.
- The body up to the surface: 3 cubits of 6 handbreadths = 18 tefachim.
- The horns (kranot): 1 cubit of 5 handbreadths = 5 tefachim.
This meticulous accounting ensures that the Altar's height is exactly "ten cubits" in generic terms, yet structurally calibrated to exactly 58 handbreadths.
The Menorah's Branch Geometry
In Chapter 3, Halachah 2, describing the Menorah’s branches:
"וְשִׁשָּׁה קָנִים יוֹצְאִין מִצִּדֶּיהָ... וְהַקָּנִים כֻּלָּם כְּמוֹ שְׁקֵדִים בַּעֲבוֹדָתָן..."[^2]
Philological Analysis
The Rambam's use of the phrase "יוֹצְאִין מִצִּדֶּיהָ" (extending from its sides) in tandem with his original diagrams in his Commentary on the Mishnah to Menachot 11:6 clarifies a major geometric point. The branches did not curve upward in a semicircle (as famously depicted on the Arch of Titus), but rose diagonally in straight lines (b'alachson).
His son, Rabbeinu Avraham, explicitly confirms this reading:
"The six branches... extended upward as straight lines, as depicted by my father, of blessed memory, and not as depicted by others."[^3]
The linguistic choice "קָנִים" (reeds/shafts) reinforces this linear, rigid geometry.
Readings
The structural laws of the Temple generate fundamental disputes regarding how the physical components of the Mikdash relate to its metaphysical sanctity.

Inherent Functional Vessel Form Material Mitzvah of Mitzvah of
Sanctity Designation is Essential is Secondary Building the Vessels
(Kedushat (Kedushat (Tzura) (Chomer) (Binyan) (Klei Shareit)
Makom) Mizbe'ach)
The Altar's Site: Inherent Sanctity vs. Functional Designation
The Rambam's View: In Chapter 2, Halachah 1, the Rambam writes:
"המזבח מקומו מכוון ביותר ואין משנין אותו ממקומו לעולם..." (The Altar is to be constructed in a very precise location, which may never be changed...)[^4]
To substantiate this, he traces the history of this site back to Adam, Cain, Abel, Noah, and the binding of Isaac.
Rav Chaim Soloveitchik of Brisk poses a classic question: Why does the Rambam include this long historical narrative in a code of law (Mishneh Torah), which typically omits aggadic history?[^5]
The Brisker Analysis: Rav Chaim explains that the holiness of the Altar's site is not a standard consecration (Kedushat Hekdesh) initiated by human dedication. Rather, it is an inherent, primordial property of the universe (Kedushat Makom).
By proving that Adam was created from this very spot—"Man was created from the place where he would find atonement" (Chapter 2, Halachah 2)—the Rambam establishes that the Altar's site is ontologically linked to human existence itself.
Therefore, this site does not require a physical Temple to project its sanctity. This explains why the returning exiles could offer sacrifices before rebuilding the Heichal (Chapter 2, Halachah 4). The site's sanctity is independent of any human-built structure.
The Menorah's Material: Tzura (Form) vs. Chomer (Material)
The Dispute: In Chapter 3, Halachah 4, the Rambam rules that if the Menorah is made of gold, it must feature goblets, bulbs, and flowers, and be hammered from a single talent of gold. However, if it is made of other metals, these ornaments are omitted, and there is no weight requirement.[^6]
The Tzofnat Paneach's Analysis: The Rogotchover Gaon (R. Yosef Rosen) analyzes this rule using the philosophical categories of Chomer (matter) and Tzura (form).[^7] He asks: Is a non-gold Menorah classified as the same vessel with modified features, or is it a structurally different category of vessel?
- The Rogotchover argues that gold is not merely an aesthetic upgrade; it is a defining element of the Menorah’s primary form (Tzurat HaGuf). When gold is used, the ornaments (gevi'im, kaftorim, u'ferachim) become essential components of that form.
- Conversely, when the Menorah is made of other metals, the halachic definition of the vessel shifts. It becomes a functional lighting utility rather than an archetypal representation of divine wisdom.
This explains why the Rambam rules that we should not add ornaments to a non-gold Menorah, rather than saying we need not add them. Adding ornaments to a non-gold Menorah would be a category error—an attempt to apply the form of a gold Menorah to a vessel that lacks its material substance.
The Temple Building: Binyan (Structure) vs. Klei Shareit (Vessels)
The Dispute: In Chapter 4, Halachah 1, the Rambam describes how King Josiah hid the Ark in deep, maze-like vaults built by King Solomon.[^8] The Ra'avad asks: Why was this detail codified as a permanent law? Furthermore, how could the Second Temple be considered a complete "House of God" when it lacked the Ark—the very vessel designed to house the tablets and serve as the seat of the Shechinah?
The Brisker Rav's Analysis: The Brisker Rav (Rav Yitzchok Ze'ev Soloveitchik) addresses this by distinguishing between two distinct obligations within the commandment of Exodus 25:8 ("Make for Me a Sanctuary"):
- The mitzvah to construct the physical building (Binyan HaBayit).
- The mitzvah to fashion and place the sacred vessels (Klei Shareit), specifically the Ark.
The Brisker Rav argues that while the Ark is essential to the functional performance of many Temple services, it is not an invalidating requirement for the structural status of the building. The Heichal is defined as a "House" by its walls, gates, and chambers, not by the objects housed within it.
By codifying Solomon’s preparation of the subterranean vaults, the Rambam reveals that the hidden chamber beneath the Temple Mount was not a temporary hiding spot, but a permanent, secondary location for the Ark.
Therefore, even when the Ark was physically absent from the Holy of Holies during the Second Temple period, it remained legally "present" within the structural boundaries of the Temple Mount. The Temple’s identity was thus preserved intact.
Friction
Kushya: The Paradox of the Muchani and Linal (Overnight Invalidation)
In Chapter 3, Halachah 14, the Rambam describes the washbasin (Kiyor) constructed by Ben Katin:
"עָשׂוּ לוֹ מְגֵרָה... כְּדֵי שֶׁיִּהְיוּ הַמַּיִם שֶׁבּוֹ תָּמִיד מְחֻבָּרִים לַמַּעְיָן... וְלֹא יִפָּסְלוּ הַמַּיִם בְּלִינָה." (A mechanism was made so that it could be filled with water at all times... and the water remaining in it did not become invalidated because the night passed.)[^9]
The mechanism (muchani) prevented the water from being invalidated overnight (linal).
The classic difficulty here, raised by the Ra'avad and analyzed in Yoma 37a and Zevachim 20b, is based on two conflicting principles:
- Sanctification of Space: The washbasin is a sacred vessel (Kli Shareit). Any water placed inside it is instantly sanctified with physical holiness (Kedushat HaGuf).
- Invalidation by Time: Once a substance is sanctified in a Kli Shareit, it becomes subject to the law of linal—meaning it is invalidated if it remains unused overnight.
How could a mechanical attachment (muchani) bypass the law of linal? If the water remains inside the washbasin (a Kli Shareit) overnight, it must be invalidated. If the muchani is not a Kli Shareit, then how can the priests use its water to sanctify their hands and feet directly, since such sanctification must be performed using a sacred vessel?

HOW TO RESOLVE THIS?

TERUTZ A: HALACHIC CHIBUR TERUTZ B: VESSEL FUNCTION
(Water remains legally connected (Muchani does not sanctify;
to the natural spring) it only stores)
Terutz A: Halachic Chibur (Connection)
The Kassef Mishneh (R. Yosef Karo) resolves this by examining the physical mechanism of the muchani.^10 The device was a pulley system that lowered the washbasin into a natural cistern or spring (Ma'ayan) beneath the Temple courtyard each night.
[ Washbasin (Kli Shareit) ] ── (pulled down at night) ──> [ Subterranean Spring ]
│
(Water becomes halachically
connected to the ground,
cancelling its "vessel" status)
From a halachic perspective, when the washbasin was lowered into the spring, the water inside became connected (mchubar) to the natural source. This connection nullified its status as "captured" water within a vessel. It reverted to being part of the natural, un-vesselled earth, which is immune to the law of linal.
In the morning, when the basin was raised, the water was considered newly "drawn" into the Kli Shareit, starting the clock for invalidation afresh.
Terutz B: The Brisker Conceptual Re-characterization
Rav Chaim Soloveitchik offers a deeper conceptual solution based on the definition of a Kli Shareit’s function.^11 He argues that a sacred vessel only sanctifies its contents when:
- The contents are placed inside with the intent to sanctify them (L'da'at).
- The vessel is in its designated functional position.
When the washbasin was lowered into the well using the muchani, it was removed from its functional position in the Temple courtyard (between the Heichal and the Altar).
By removing the vessel from its designated space, its capacity to sanctify its contents was suspended. The water inside did not retain its active state of Kedushat HaGuf overnight, and was therefore protected from invalidation by linal.

The "Sacrifices without a Temple" Principle
In Chapter 2, Halachah 4, the Rambam mentions that the returning exiles brought three prophets with them:
"שְׁלֹשָׁה נְבִיאִים עָלוּ עִמָּהֶם מִן הַגּוֹלָה... וְאֶחָד הֵעִיד שֶׁמַּקְרִיבִין אֶת הַקָּרְבָּנוֹת כֻּלָּם אַף עַל פִּי שֶׁאֵין בַּיִת." (Three prophets returned... one attested to the site... the second to its dimensions; and the third to the Halachah permitting all sacrifices to be offered even though the Temple itself was not built yet.)[^12]
This historical event is directly linked to a fundamental halachic principle codified in Mishnah Eduyot 8:6:
"שָׁמַעְתִּי שֶׁמַּקְרִיבִין אַף עַל פִּי שֶׁאֵין בַּיִת..." (I heard that we may offer sacrifices even though there is no Temple...)
This principle is supported by the following biblical and halachic references:
| Source | Text | Halachic Application |
|---|---|---|
| Ezra 3:3 | "וַיָּכִינוּ הַמִּזְבֵּחַ עַל־מְכוֹנֹתָיו..." | They established the Altar before the foundations of the Temple were laid, validating sacrifices without a standing Heichal. |
| Rambam, Beit HaBechirah 6:16 | "קְדֻשָּׁה רִאשׁוֹנָה קִדְּשָׁה לִשְׁעָתָהּ וְקִדְּשָׁה לֶעָתִיד לָבֹא..." | The original sanctification of Jerusalem by King Solomon remains eternally active, preserving the site's holiness even in ruins. |
| Responsa Chatam Sofer YD 236 | Discussion of R. Yechiel of Paris (13th Cent.) | Explores the practical feasibility of offering the Passover sacrifice in medieval times, relying on this ongoing sanctity. |
This ongoing sanctity is why the Rambam goes to great lengths in Chapter 2 to define the exact dimensions of the Altar. Since the site's holiness is eternal, any future restoration of the sacrificial service depends entirely on building the Altar in its precise location and to its exact proportions.
The Double Curtains (Ama Teraxin) and the Yom Kippur Entry
In Chapter 4, Halachah 2, the Rambam explains that the Second Temple used two curtains separated by a one-cubit gap (Ama Teraxin) instead of the one-cubit solid wall used in the First Temple.^13 This architectural change was made because the builders were unsure whether the wall's width was legally part of the Heichal (the Sanctuary) or the Kodesh HaKodashim (the Holy of Holies).
This created a major spatial challenge for the High Priest on Yom Kippur, as described in Yoma 52b:
[ Heichal (Sanctuary) ] ──> [ Outer Curtain ] ──> [ Ama Teraxin (1 Cubit Gap) ] ──> [ Inner Curtain ] ──> [ Kodesh HaKodashim ]
│
(The High Priest walked north
through this buffer zone
to reach the inner entrance)
The High Priest had to walk between these two curtains to enter the Holy of Holies. This one-cubit gap was an ambiguous zone—neither fully holy nor fully mundane.
By detailing this layout in Chapter 4, the Rambam shows that the physical design of the Second Temple was built around this unresolved halachic doubt. Rather than attempting to resolve the question with a single curtain, the architecture itself was designed to accommodate the ambiguity, transforming a conceptual doubt into a permanent physical feature.
Psak/Practice
How do these ancient architectural laws apply to contemporary halachic practice and meta-halachic decision-making?

The Geometry of the Temple Mount Today
The eternal nature of the Temple's sanctity (Kedushah rishonah kidsha l'atid lavo) means that entering the area of the Azarah (the Temple Courtyard) while ritually impure remains a severe transgression (Karet). Because we cannot identify the exact boundaries of the Altar and the courtyard with perfect certainty, contemporary halachic authorities prohibit entering the inner areas of the Temple Mount.
[ Ancient Temple Layout ] ── (overlay) ──> [ Modern Temple Mount ] ──> [ Halachic Restriction Zone ]
The Rambam’s precise dimensions in Chapters 2 and 4 serve as the basis for all modern attempts to map the site. Archaeologists and halachic scholars use these measurements to calculate the location of the Even HaShtiah (the Foundation Stone) and determine which areas of the mount are permitted to visit.
The Metrics of the Ama (Cubit)
The Rambam’s discussion of five-handbreadth and six-handbreadth cubits in Chapter 2, Halachah 6, is central to the ongoing debate over modern halachic measurements.
This debate is primarily split between two major opinions:
THE MODERN CUBIT DEBATE

└───────────────────────────────────────────┘ └───────────────────────────────────────────┘
- Rav Chaim Naeh: Argues for a smaller cubit of approximately 48 centimeters, based on historical and archaeological records.^14
- The Chazon Ish: Argues for a larger cubit of approximately 58 to 60 centimeters, based on calculations of the volume of water required for halachic vessels.^15
When applied to the dimensions of the Altar (32 by 32 cubits), this difference is significant:
$$\text{Width (Rav Chaim Naeh)} = 32 \times 48\text{ cm} = 15.36\text{ meters}$$
$$\text{Width (Chazon Ish)} = 32 \times 58\text{ cm} = 18.56\text{ meters}$$
This discrepancy of over three meters affects where the boundaries of the Altar would lie, highlighting how the Rambam's dimensional details continue to shape practical halachic decisions today.
Takeaway
The physical dimensions of the Temple are not merely historical blueprints; they are the spatial translation of eternal halachic concepts. Whether we are measuring the Altar's base or navigating the curtains of the Holy of Holies, we learn that holiness in Judaism is not an abstract feeling, but a highly structured reality defined by precise physical boundaries.
