ויקרא, פרק א׳, פסוק י״ב

Bringing a burnt offering to God requires strict precision and order. The entire animal is carefully taken apart and placed upon the altar in a highly systematic manner. Although the instructions for cutting an offering are established earlier for cattle, they are repeated for sheep and goats. This teaches that even a smaller animal must be systematically divided into proper portions rather than being placed on the altar whole [בכור שור, חזקוני]. While the step of skinning the animal is not explicitly repeated, it is understood that a small animal requires skinning just like a large one [בכור שור, חזקוני].

The process of dividing the animal is not done randomly, but through a professional, orderly separation, similar to the work of a skilled butcher. The body is broken down into its main limbs, yet these individual sections must not be chopped into smaller pieces [הכתב והקבלה]. Within this process, the head and the suet—the fat separated from the meat—are treated distinctly from the rest of the body [ביאור שטיינזלץ]. This distinction exists because the head is already severed during the initial slaughter, does not require skinning, and must not be cut into additional parts [מלבי״ם]. While severing the head and removing the fat are not considered standard dismemberment, they still fall under the broader requirement of cutting and separating the offering [שד״ל, רד״צ הופמן].

When the offering is prepared, the fat is spread over the area of the head where the slaughter took place [מלבי״ם]. As the priest places the offering on the fire, he must follow a precise sequence. Because the head and the fat are treated distinctly, they are the very first items brought up to the altar, preceding all other limbs [תורה תמימה, מלבי״ם, אדרת אליהו]. Finally, the priest does not place the remaining pieces on the wood in a haphazard way; he arranges them in the exact order in which they were originally separated from the animal [מלבי״ם, אדרת אליהו].
