This tractate systematically organizes the laws of sacrifices, including the types of offerings, their validity, and the procedures for slaughter, catching blood, and sprinkling. It is the classic Chazal framework for Temple offerings.

Certain unfit items, once they have been placed on the altar, are nevertheless sacrificed. The mishna teaches: The altar sanctifies only items that are suited to it. The tanna’im disagree as to the definition of suited for the altar. Rabbi Yehoshua says: Any item that is suited to be consumed by the fire on the altar, e.g., burnt offerings and the sacrificial portions of other offerings, which are burned on the altar, if it ascended upon the altar, even if it is disqualified from being sacrificed ab initio, it shall not descend. Since it was sanctified by its ascent upon the altar, it is sacrificed upon it, as it is stated: “It is the burnt offering on the pyre upon the altar” (Leviticus 6:2), from which it is derived: Just as with regard to a burnt offering, which is suited to be consumed by the fire on the altar, if it ascended it shall not descend, so too, with regard to any item that is suited to be consumed by the fire on the altar, if it ascended it shall not descend. Rabban Gamliel says: With regard to any item that is suited to ascend upon the altar, even if it is not typically consumed, if it ascended, it shall not descend, even if it is disqualified from being sacrificed ab initio, as it is stated: “It is the burnt offering on the pyre upon the altar,” from which it is derived: Just as with regard to a burnt offering, which is fit for the altar, if it ascended it shall not descend, so too, any item that is fit for the altar, if it ascended it shall not descend. The mishna comments: The difference between the statement of Rabban Gamliel and the statement of Rabbi Yehoshua is only with regard to disqualified blood and disqualified libations, which are not consumed by the fire but do ascend upon the altar, as Rabban Gamliel says: They shall not descend, as they are fit to ascend upon the altar, and Rabbi Yehoshua says: They shall descend, as they are not burned on the altar. Rabbi Shimon says: Whether the offering was fit and the accompanying libations were unfit, e.g., if they became ritually impure or they were brought outside their designated area, or whether the libations were fit and the offering was unfit, rendering the accompanying libations unfit as well, and even if both this and that were unfit, the offering shall not descend, as it was sanctified by the altar, but the libations shall descend. Any offering that is more frequent than another precedes the other offering. Therefore, the daily offerings precede the additional offerings, which are sacrificed only on certain days. When Shabbat and the New Moon coincide, the additional Shabbat offerings precede the additional New Moon offerings. Likewise, the additional New Moon offerings precede the additional New Year offerings. The mishna cites the source for the principle that the frequent precedes the less frequent: As it is stated with regard to the additional offerings of the first day of Passover: “Besides the burnt offering of the morning, which is for a daily burnt offering, you shall offer these” (Numbers 28:23). The verse indicates that the daily offering is sacrificed first, and then the additional offerings are sacrificed. Any offering that is more sacred than another precedes the other offering. The mishna elaborates: If there is blood of a sin offering and blood of a burnt offering to be presented, the blood of the sin offering precedes the blood of the burnt offering because it effects acceptance, i.e., atonement, for severe transgressions punishable by karet. Likewise, if there are limbs of a burnt offering and portions of a sin offering to be burned on the altar, the burning of the limbs of the burnt offering precedes the portions of the sin offering, because the burnt offering is entirely burned in the flames on the altar, whereas only part of the sin offering is burned. Similarly, although both effect atonement, a sin offering precedes a guilt offering due to the fact that its blood is placed on the four corners of the altar and the remnants of its blood are poured on the base of the altar, whereas the blood of the guilt offering is sprinkled on only two corners of the altar. A guilt offering precedes a thanks offering and the nazirite’s ram due to the fact that it is an offering of the most sacred order, and the others are offerings of lesser sanctity. A thanks offering and a nazirite’s ram precede a peace offering due to the fact that they are eaten for one day, like offerings of the most sacred order, whereas a peace offering is eaten for two days, and the thanks offering and nazirite’s ram require loaves to be brought with them, four types with the thanks offering and two types with the nazirite’s ram. Sacrifice of the peace offering precedes sacrifice of the firstborn offering due to the fact that the peace offering requires placing the blood on the altar, in the form of two placements that are four, and placing hands on the head of the offering, and libations, and the wavings of the breast and the thigh by the priest and the owner; none of which is required for the firstborn offering.
