Mishneh Torah, The Chosen Temple 2-4

Sugya Map

• Primary Issue: The ontological and physical fixity of the Altar's site and structure (the Makom).
• Core Question: Is the holiness of the Altar site inherent to the geography, or a consequence of prophetic/Divine selection?
• Nafka Mina: Can a Beit HaMikdash exist without the original Even HaShtiah? Does the historical "universal acceptance" of the site create a halachic status quo that binds the Messianic era?
• Primary Sources: Mishneh Torah, The Chosen Temple 2:1-4, Zevachim 62a, Genesis 22:2, II Chronicles 3:1.

Text Snapshot

Rambam opens Hilchot Beit HaBechirah 2:1 with a striking imperative: "The Altar is [to be constructed] in a very precise location, which may never be changed." The dikduk here is crucial. Rambam uses the phrasing Makom mechuvvan me'od—"a very precise place." He invokes the tradition that the site of the Altar is the site of the Akedah, the site of Noah’s sacrifice, and even the site of Adam’s creation. The shift from the Akedah (Abraham) to the Goren Ornan (David/Solomon) serves to collapse historical time into a singular, immovable geometric point.

Readings

The Rambam: The Prophetic Anchor

Rambam’s chiddush is that the sanctity of the Altar site is not a spontaneous eruption of nature, but a result of tradition and prophetic validation. By listing the succession of patriarchs—Adam, Cain, Abel, Noah, Abraham—Rambam transforms the Temple Mount into a historical continuum. The "universal acceptance" mentioned in Halachah 1 signifies that the site’s holiness is an objective fact recognized even by those outside the covenant. This is not merely historical flavor; it is a legal claim that the Makom is immutable because it has been "chosen" by the Divine through the acts of the prophets.

The Chatam Sofer: The Necessity of Dimensions

The Chatam Sofer (Responsum Yoreh De'ah 336) focuses on the "three prophets" mentioned in Halachah 2. He argues that the reason we cannot offer sacrifices today is not merely the lack of a building, but the lack of the prophetic confirmation of the precise dimensions and the status of the Altar. The Chatam Sofer posits that the Altar is not just a pile of stones; it is a "vessel" whose validity depends on an exact, prophetically-mandated measurement. Without that mandate, the structure is chullin (mundane), regardless of how accurately we measure the cubits.

Friction

The Strongest Kushya: Rambam states in Hilchot Beit HaBechirah 2:10 that the Altar's base does not encircle the entire structure; specifically, the southeast corner lacks a base because that portion of the land belongs to the tribe of Judah, while the rest belongs to Benjamin. How can a Mitzvah (the construction of the Altar) be dependent on the accidental borders of tribal inheritances? If the Altar is the "Foundation of the World," why should legalistic tribal boundaries interfere with its structural perfection?

The Terutz: The Likkutei Sichot (Vol. 19) provides a profound resolution: The Altar, while occupying the "Foundation Stone" of the world, must still be integrated into the human order of the Twelve Tribes. By "missing" a base in the territory of Judah, the Altar serves as a bridge between the physical world of tribal divisions and the transcendent holiness of the Shechinah. The "deficiency" is actually a feature: it demonstrates that even the most holy site must respect the legal boundaries established by the Torah for the land of Israel. It prevents the Altar from being "de-localized" or abstracted from the reality of the Jewish people inhabiting the land.

Intertext

• Zevachim 62a: The locus classicus for the prophetic involvement in the site selection. The Talmud debates whether David saw the "Heavenly Altar" or the "ashes of Isaac." Rambam synthesizes these into a single narrative of continuity.
• Genesis 22:2 & II Chronicles 3:1: These verses form the "chain of title" for the Temple Mount. Rambam uses Chronicles to bridge the gap between the Akedah and the Goren Ornan, creating a seamless narrative of Divine ownership of that specific coordinate.

Psak/Practice

The meta-psak heuristic here is Hamakom Hu HaHalacha. In contemporary Jewish practice, this manifests in the strict prohibition against entering the Har HaBayit (Temple Mount) among the vast majority of Haredi and many Modern Orthodox authorities. The "precise location" is so sacred and its boundaries so critical that the risk of stepping on the forbidden Makom—where the Altar once stood—outweighs the desire for proximity. The Rambam’s emphasis on the exactness of the location is the primary halachic source for this caution.

Takeaway

The Altar is the anchor of reality; its location is not a matter of convenience, but an ontological necessity that links the creation of man to the Messianic future. To build the Altar is not to create holiness, but to uncover the site where the Divine and the human have always met.
