ויקרא, פרק א׳, פסוק ח׳

Elevating an offering upon the altar is not merely a technical procedure, but a meticulously orchestrated process requiring order, dignity, and strict attention to detail. This careful arrangement reflects the transition of the physical offering from the mundane realm into the holy, performed with deep reverence for God. Because cattle are large and heavy animals, the physical labor demands the participation of multiple priests, as opposed to a smaller sheep offering which can be handled by a single individual [דעת זקנים, חזקוני, הדר זקנים]. This collective effort dictates a specific distribution of labor among the priests, ensuring the service is executed with both swiftness and public splendor [תורה תמימה, מלבי״ם, רד״צ הופמן, רש״ר הירש]. The responsibility is explicitly assigned to the sons of Aaron. Some explain that Aaron himself was initially excluded from these specific duties as a consequence of the Golden Calf, until Moses pleaded to God on His brother's behalf [פענח רזא]. Furthermore, the priests must be dressed in their proper, designated garments. The service is entirely invalidated if a regular priest wears the eight garments of the High Priest, or if the High Priest officiates wearing the four garments of a regular priest [רש״י, מזרחי, תורה תמימה, משכיל לדוד, רש״ר הירש].

The actual placement of the animal's limbs upon the fire must be executed with the careful precision of setting a royal table [ביאור יש״ר]. The head is treated as a distinct component from the rest of the body parts. Because it is severed during the initial slaughter, it bypasses the subsequent flaying process and must be handled as an independent piece [רש״י, רבנו בחיי, שפתי חכמים, תורה תמימה, מלבי״ם, בכור שור, גור אריה]. Furthermore, due to its importance, the head is the first part to be offered [רלב״ג, רש״ר הירש]. It is brought up to the altar together with the suet, which the primary approach among commentators identifies as the thin, net-like fat covering the abdomen. This fat serves as a partition between the upper and lower intestines, a function hinted at by the Hebrew word for suet, which shares its root letters with the word for "separate" [רמב״ן, טור, רבנו בחיי, ביאור יש״ר, רד״צ הופמן]. During the offering, this fat is intentionally draped over the severed neck to conceal the blood. Hiding the unsightly area of the slaughter is a profound show of respect toward Heaven, mirroring the way nobility would respectfully cover roasted meat with fat [רש״י, רמב״ן, רבנו בחיי, תורה תמימה, רלב״ג, בכור שור].

Finally, the placement of the wood and the fire on the altar follows strict guidelines. The wood must be highly combustible, which disqualifies certain types like vine and olive branches [תורה תמימה, רש״ר הירש, אדרת אליהו]. The arrangement of both the wood and the meat must be kept compact and precise; no piece may protrude beyond the designated burning area, ensuring the priests can walk around the altar without obstruction [רש״י, שפתי חכמים, תורה תמימה, עמק דבר, דברי דוד]. The altar itself sets the standard for everything placed upon it. Just as the altar is public property and strictly forbidden from being used for everyday purposes, the wood and fire must also be provided by the public and must never have been used for any mundane task [תורה תמימה, רש״ר הירש, אדרת אליהו].
