The Avodah (service) of the Sanctuary is a Divine chok — a precise legal decree that must be performed according to exact parameters. It is not a collection of symbols, nor a hidden pattern to be deciphered through external sources. Rather, it is an internally consistent legal system whose blueprint and operating instructions are preserved in the Torah and the Mishnah.
I. The Mizbe’ach: The Fixed Foundational Place
The location of the Altar is fixed for all generations and may never be changed.
1 Chronicles 22:1
“וַיֹּאמֶר דָּוִיד זֶה הוּא בֵּית יְהוָה הָאֱלֹהִים וְזֶה מִּזְבֵּחַ לְעֹלָה לְיִשְׂרָאֵל.”
“And David said: This is the house of the Lord God, and this is the Altar for the burnt offerings of Israel.”
This is the Makom where Adam offered, where Noah offered after the Flood, and where Isaac was bound (tradition codified in Rambam, Hilkhot Beit HaBechirah 2:1-2). It serves as the legal “Ground Zero” where a person’s status before Hashem is altered through valid korbanot.
II. The Language of the Blood: Zeriqah and Matan
The Torah and Mishnah distinguish two primary actions for the application of blood on the Outer Altar:
Zeriqah (זְרִיקָה) — Throwing or dashing the blood from a distance against the sides of the Altar.
Leviticus 1:5 (Olah):
“…וְזָרַקוּ בְּנֵי אַהֲרֹן הַכֹּהֲנִים אֶת־הַדָּם עַל־הַמִּזְבֵּחַ סָבִיב.”
“…and the sons of Aaron the priests shall throw the blood against the Altar round about.”
Matan / Netinah (מַתָּן / נְתִינָה) — Deliberate placement of blood with the finger directly on the four horns (kranot).
Leviticus 4:30 (Chatat of a common person):
“…וְלָקַח הַכֹּהֵן מִדָּמָהּ בְּאֶצְבָּעוֹ וְנָתַן עַל־קַרְנוֹת הַמִּזְבֵּחַ…”
“…and the priest shall take of its blood with his finger and put it on the horns of the Altar…”
The remainder of the blood (שִׁיְרֵי הַדָּם) is poured at the base of the Altar (the Yesod).
III. The Physical Tavnit of the Yesod
The structure of the Altar and its base is described with precision in the Mishnah, reflecting the actual Second Temple:
Mishnah Middot 3:1:
הַמִּזְבֵּחַ הָיָה שְׁלֹשִׁים וּשְׁתַּיִם עַל שְׁלֹשִׁים וּשְׁתַּיִם. עָלָה אַמָּה וְכָנַס אַמָּה, זֶה הַיְסוֹד. … וְהַיְסוֹד הָיָה מַקִּיף אוֹתוֹ כֻּלּוֹ, וְהָיָה נִרְאֶה מִן הַצָּפוֹן וּמִן הַמַּעֲרָב, וְנוֹתֵר אַמָּה לַדָּרוֹם וְאַמָּה לַמִּזְרָח.
Translation:
“The Altar was thirty-two cubits by thirty-two cubits. It rose one cubit and drew in one cubit — this is the Yesod. … And the Yesod encircled it entirely, but it was visible from the north and from the west, and there remained one cubit to the south and one cubit to the east.”
Thus, the projecting Yesod was fully visible and functional along the northern and western sides. It extended (“turned the corner”) only one cubit at the south-western corner and one cubit at the north-eastern corner. The south-eastern corner did not have a projecting Yesod in the same manner.
Zeriqah was performed toward the north-eastern and south-western corners to achieve coverage on all four sides. The remainder blood was poured at the base, with drainage concentrated at the south-western corner through two openings (Mishnah Middot 3:2).
This exact physical tavnit is part of the legal protocol. The blood rites had to be performed in accordance with the actual revealed structure of the Altar.
IV. The Chut HaSikra: The Red Line
A crimson line (חוּט הַסִּיקְרָא) encircled the Altar at its midpoint. This line served as a clear visual boundary to distinguish between blood that was to be placed above it and blood that was to be placed below it, according to the requirements of each type of offering (Mishnah Middot 3:1 and related discussions in Zevachim).
This architectural feature reinforced that kedushah is expressed through meticulous adherence to the detailed parameters of the chok.
V. Kapparah: Legal Acquittal
Leviticus 17:11 states the foundation of the system:
“כִּי נֶפֶשׁ הַבָּשָׂר בַּדָּם הִוא וַאֲנִי נְתַתִּיו לָכֶם עַל־הַמִּזְבֵּחַ לְכַפֵּר עַל־נַפְשֹׁתֵיכֶם כִּי הַדָּם הוּא בַּנֶּפֶשׁ יְכַפֵּר.”
Translation:
“For the life of the flesh is in the blood, and I have given it to you upon the Altar to make atonement for your souls; for it is the blood that makes atonement by reason of the life.”
Kapparah is achieved when the blood is applied according to the precise legal protocol of the tavnit. The Kohen acts as the authorized agent executing the King’s decree. The goal is covenantal restoration — moving the individual or the nation from liability to purity.
Conclusion
The Torah commands the service. The Mishnah provides the detailed operating instructions as practiced in the Second Temple. Nothing is “hidden.” The protocol was openly transmitted by those who served in the Sanctuary. When studied according to the proper order — Tanakh first, then Mishnah — the precision and internal consistency of the system become self-evident.
The Altar of Foundation stands as testimony to the exactness of Hashem’s revealed will. Every detail of its tavnit and every step of its legal protocol calls us to approach Him with complete fidelity to what He has shown.
