Preparing a sacrifice requires strict attention to cleanliness and precise order, marking the transition from a physical animal to a spiritual gift presented before God. Before the offering of the flock is transformed into fire and smoke, its internal organs and legs must be washed in water [ביאור שטיינזלץ]. This washing preserves the dignity of the Altar. Since the sacrifice is brought to the table of a King, it is entirely inappropriate to offer anything unclean or repulsive [פענח רזא, הדר זקנים, פרדס יוסף]. This contrasts with sin offerings, which are burned outside the camp in a secular area and therefore do not require such washing.
The instructions for washing the innards and legs are phrased broadly, hinting at situations where the limbs of different burnt offerings become mixed together. This was a particularly common occurrence with individual offerings from the flock, as they were often brought immediately following the daily morning sacrifice, making it highly likely for their parts to intermingle [העמק דבר, מלבי״ם].
Following the washing, the priest gathers the parts. This action refers specifically to the physical carrying of the limbs to the Altar's ramp, emphasizing that the transport itself is a sacred service that must be performed by a priest [תורה תמימה, חזקוני, אדרת אליהו, חתם סופר, רד צ הופמן]. This specific step is highlighted for the flock offering because these animals are slaughtered in the northern part of the courtyard, while the ramp is located in the south. Therefore, the limbs must be intentionally carried across the space [חתם סופר]. Alternatively, this detail is omitted from the earlier instructions regarding cattle to teach that the physical size of a sacrifice holds no inherent advantage. A person should not mistakenly believe that a massive bull is more desirable to God; rather, Torah study and good deeds are what truly matter [אדרת אליהו].
Once at the Altar, the priest places the limbs on the fire to turn them into smoke. He does not create the smoke directly but facilitates its ascent. Unlike ordinary, eye-burning smoke produced by burning matter, this smoke consists of the spiritual vapor and moisture rising from the flesh, which together create a pleasing aroma to God [הכתב והקבלה]. The distinction between carrying the limbs and turning them into smoke addresses complex scenarios. For instance, a priest might carry certain parts, like bones and sinews, but ultimately not burn them if they have separated from the meat. Conversely, he might burn invalid parts that never should have been carried in the first place, provided they have already reached the top of the Altar [מלבי״ם].
The process concludes by affirming the status of the sacrifice as a burnt offering. While the specific phrasing refers directly to the male sheep or goat being offered [ביאור יש״ר], it also establishes a crucial legal framework of validation and invalidation. The definition of the burnt offering retroactively validates the sacrifice even if certain secondary procedures were neglected, such as failing to flay the skin, cut the animal into distinct limbs, or have the owner press his hands upon it. However, the offering is completely invalidated if the animal was not slaughtered in the northern section of the courtyard. Slaughtering in the north is a fundamental requirement that precedes atonement and applies to all burnt offerings. In contrast, flaying, cutting, and pressing hands are secondary steps that either occur after atonement is achieved or do not apply universally to all burnt offerings [אור החיים, מלבי״ם, אילת השחר, רד צ הופמן, אדרת אליהו].
