The Incense Altar is discussed separately from the other vessels because it played a significantly different role than them. This position divides in its evaluation of that role:
The Incense Altar played only a technical role in the Mishkan, and had a much lower status than the other vessels in the Sanctuary.
Last is least – This approach assumes that the vessels are listed in order of their significance. Thus, if an object found at the end of the list, this implies that it is less important.
Function of the Incense Altar – Rambam asserts that the Incense Altar functioned as a deodorizer for the Mishkan. The odors of the animal slaughter and blood would have been overwhelming if they were not countered by the fragrance of the incense.
5 He adds that it was necessary to ensure that there was a pleasant fragrance for, otherwise, the people would not properly honor the Mikdash.
Context – Discussion of the Incense Altar is followed by a description of the water basin (כיור), also a secondary vessel which played no role in any cultic rite, and only served to clean and prepare the priests for service. This context, thus, supports this approach's position that the Incense Altar also played merely a technical role.
Morning and evening – The incense was burned both in the morning and evening, around the time of the daily sacrificial offerings whose scent it was meant to counter.
6 Placement of the Altar in the Tabernacle – One might question, if the incense was meant to clear the air from the burning flesh, why was it placed inside the sanctuary rather than outside, near the Copper Altar where the animals were being sacrificed? Rambam might respond that it is specifically in the enclosed space of the Tabernacle that the odor would have been overwhelming. The altar was, thus, placed inside, but close to the outside curtain so as to most effectively accomplish its its goal.
Golden materials – If the altar was simply a deodorizer, it is not clear why it needed to be made of the most precious of metals, gold. Rambam could reply that everything in the Tabernacle, regardless of their function, needed to be made of the highest quality materials both to honor God and to ensure that the people felt that the Tabernacle was worthy of glory.
7 Can laws be utilitarian in nature? One might question whether it is possible that laws might be ordained for purely practical purposes, with no spiritual benefit. Rambam, though, is consistent in reading various laws as being utilitarian in nature. See, for example, his understanding of the laws of
Shemittah and
Kashrut.
Incense on Yom HaKippurim – The Yom HaKippurim service, which mandates that the high priest light incense and bring it to the Holy of Holies, is difficult for Rambam, as it is hard to say that this, too, was necessary merely to freshen the air.
.8 Moreover, the rite suggests that the incense burning was not considered a lowly ritual, but one of the most exalted of offerings.
9 Incense in the story of Korach – One might further question this position's view of the incense from the story of Korach's rebellion. If the incense played such an insignificant role in the Tabernacle, why was it chosen to test who merited the priestly position?
Punishment of "כרת" –
R. Bachya further questions, if the incense was commanded for such a mundane reason, why is the death penalty is given to any who makes it on his own?
The Incense Altar played an important role which was distinct from, but complemented the other service in the Mishkan.
Purpose of the Mishkan – According to these sources, the main function of the Mishkan, its vessels, and service was to invite and house Hashem's presence.
11 Seforno suggests that the Ark, from which Hashem spoke to Moshe, served as Hashem's throne, while the outer sanctuary with the Table and Menorah were like a living room.
12 The sacrificial service on the Copper Altar is man's active attempt to draw God's presence down into the Mishkan. Thus, each vessel, with the notable exception of the Incense Altar, serves a key role in transforming the Mishkan into Hashem's home.
13 Function of the Incense Altar – These sources differ in how they view the purpose of the incense and its altar:
- Honor - Seforno14 suggest that the incense is brought not to invite Hashem's glory, but rather to honor it once it has already arrived.15
- Atonement - Ramban and the Gr"A, instead, suggests that the Incense Altar plays an atoning role.16 This was not necessary to usher in the Divine Presence, but perhaps helped to ensure that it did not depart..
- Screen - R"M Leibtag, R"E Samet and R"Y Grossman all suggest that, in contrast to the other vessels which were meant to invite the Divine presence, the cloud of incense was meant to screen the revelation.17 The Mishkan created a paradox. Man, craving closeness, invites Hashem to dwell, but Hashem's Holy presence means that man must keep a distance. Thus, the cloud of incense served to create a barrier to protect the people and enable the encounter.18
"וְשָׁכַנְתִּי בְּתוֹךְ בְּנֵי יִשְׂרָאֵל" – Chapters 25-29 are sandwiched by the two statements "וְעָשׂוּ לִי מִקְדָּשׁ וְשָׁכַנְתִּי בְּתוֹכָם" and "וְשָׁכַנְתִּי בְּתוֹךְ בְּנֵי יִשְׂרָאֵל", suggesting that everything that was commanded in between was intended to accomplish this goal of creating a dwelling place. The fact that the command regarding the Incense Altar comes only after this inclusio, supports this position's understanding that it, in contrast, was not meant to invite or house the Divine presence.
Context – The discussion of the altar is found together with a discussion of other aspects of the Mishkan, like the basin, half shekel coins, and anointing oil which similarly play no role in inviting the Divine presence.
Location in the sanctuary – R. Samet suggests that the verse emphasizes that the altar faced the Ark "were I will meet with you" to highlight that the incense was meant to screen that revelation. It is also possible that its position in the outer sanctum was meant to show that, despite its distinct function, it was of equal importance to the adjacent Menorah and Table.
Morning and Evening – Seforno suggests that the incense is brought specifically when the daily sacrifices are offered, so that when Hashem descends to accept them, the nation can greet Him with honor, ensuring that the offerings are accepted with favor. The modern scholars might similarly explain that each day, right as the sacrifices are to usher in Hashem's presence, a screen is needed to protect the people.
