Verse Ex29-12c discussing the blood procedures during
the sacrifices states
And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger; and thou shalt pour out all the remaining blood at the base of the altar.
To understand the Rashi on this verse we first cite Rav Hirsch's comments on
Nu28-06 which discusses the daily offerings and states
It is a continual burnt offering, produced at Mount Sinai for a sweet savor, a sacrifice made by fire to the Lord.
Rav Hirsch notes that the daily offerings were not produced at Mount Sinai but offered
on the altar. Therefore, concludes, Rav Hirsch, The altar resembled a mountain
in appearance starting with a wide base and having a small top. The diagram below
depicts this. Rav Hirsch further explains The altar resembled Mount Sinai since
the sacrifices inspired prophecy and Mount Sinai was the original national prophetic
revelantion. Therefore the altar resembled Mount Sinai so as to symbolically confirm
prophetic capability of the people.
' ----- ALTAR TOP
' ---------------------- ALTAR BASE
The actual dimensions and height of each component are mostly given
through tradition and cannot be inferred from textual sources. The height
of the altar base was minimal, 1 cubit. Rashi explains that There was
an indentation on top of the altar base; the indentation served as a receptacle
for the blood poured to the foundation. The diagram below depicts
' | | Altar base
' | | Each side had an indentation.
' | | Blood could be poured in
' | | This indentation.
Since this Rashi clarifies diagrams we classify it as a NonVerse, Diagramatic
