Bringing a peace offering requires precise attention to detail, not just in selecting which inner organs are placed on the altar, but also in the exact timing of their removal. The primary approach among commentators is that the separation of these inner parts must occur while the animal is still entirely whole. It is strictly forbidden to butcher or cut the meat before extracting the specific portions designated for the altar [תורה תמימה, מלבי״ם, אדרת אליהו, רד צ הופמן]. The underlying logic is that as long as the animal remains intact, it retains its original, unified identity as a single body. Once it is cut into pieces, it loses this unified identity and becomes mere meat or separate limbs. Therefore, the instruction to take the offering directly from the animal requires the extraction to happen while the body is still complete [תורה תמימה, מלבי״ם]. While a simpler view suggests this instruction merely means taking a portion from the general sacrifice [שד״ל], the requirement directly connects to the physical wholeness of the animal prior to butchering [רד צ הופמן].
In this specific stage of the process, the concept of the offering itself is understood in a very narrow sense. It does not refer to the entire animal brought to the Tabernacle, but exclusively to those specific inner parts that are separated and elevated upon the altar [רד צ הופמן]. Furthermore, the explicit instruction to remove the fat is detailed again for the goat, even though identical procedures were already outlined for other animals like bulls and sheep. Because bulls and sheep have distinct and unique laws governing their sacrifices, one might mistakenly assume that the rules for their inner parts do not automatically apply to a goat. To prevent any misunderstanding, the instructions regarding the fat are repeated, ensuring that these specific portions of the goat are offered correctly [מלבי״ם, אדרת אליהו].
