ויקרא, פרק ג׳, פסוק ז׳

Bringing a peace offering involves precise instructions tailored to the specific type of animal being presented. By categorizing the offerings, the Torah highlights the unique characteristics and requirements of each species. For instance, when a mature, fully grown sheep is selected, the process follows distinct guidelines compared to younger animals [הטור הארוך, פענח רזא, העמק דבר, קיצור בעל הטורים].

The primary approach among commentators questions why the instructions for a sheep are presented in a completely separate section from those of a goat, especially since the two are grouped together in the laws of the voluntary burnt offering. The reason stems from a key anatomical and legal difference. A sheep possesses a distinct fat tail that must be burned on the altar, a feature that a goat lacks. Because of this essential difference in the offering process, the two animals are addressed independently [רש״י, מזרחי, שפתי חכמים, ביאור יש״ר]. Additionally, the goat could not simply be grouped with the preceding instructions for cattle. Cattle are considered a more prestigious and significant offering than animals from the flock, necessitating their own distinct presentation [גור אריה].

The specific laws governing the sheep also serve to expand the rules of the offering to cover additional scenarios. First, they establish that the Passover offering, which is also brought from sheep, requires its fat tail to be burned on the altar, even though this is not explicitly stated in the Passover instructions [תורה תמימה, חזקוני, העמק דבר]. Furthermore, this expansion applies to situations where a Passover offering transitions into a peace offering. This can occur if the animal's designated year has passed, if it serves as a substitute for a Passover offering, or if it is an accompanying peace offering brought alongside it. In all these instances, the animal is treated completely as a standard peace offering. It requires the owner to lean their hands upon it, the pouring of libations, and the formal waving of the breast and thigh [תורה תמימה, מלבי״ם, אדרת אליהו]. The law also extends to the first offspring of a peace offering, dictating that it must be offered as a peace offering itself [תורה תמימה].

Conversely, the laws also introduce specific limitations. They emphasize that a voluntary peace offering can only be brought by an individual, not by the public. This clarification is particularly necessary regarding sheep. Since the public is required to bring sheep as a mandatory peace offering during the holiday of Shavuot, one might mistakenly assume the public could also bring them as voluntary peace offerings. The law clearly prevents this [תורה תמימה, מלבי״ם, רד צ הופמן]. Additionally, this limitation excludes the offspring of a tithed animal from being offered on the altar. Instead, such an animal must simply graze until it develops a physical blemish, after which the owner may eat it [תורה תמימה].

Finally, the requirement to present the offering before God mandates that the individual bringing the animal must physically bring it into the courtyard, right to the entrance of the Tent of Meeting [ביאור יש״ר, ביאור שטיינזלץ].
