Zevachim 8A

״ולקח הכהן מדם החטאת״⁠ – שתהא קבלה לשם חטאת.

“And the priest should take of the blood of the sin offering” (Leviticus 4:25), teaching that the collection of the blood must be performed for the sake of a sin offering.

ואשכחן שחיטה וקבלה, זריקה מנלן? דאמר קרא: ״וכפר עליו הכהן מחטאתו״⁠ – שתהא כפרה לשם חטאת.

The Talmud asks: And we found a source for the halakha that the slaughter and collection must be performed for the sake of a sin offering. From where do we derive this halakha with regard to the sprinkling of the blood? The Talmud answers: It is derived from a verse, as the verse states: “And the priest should make atonement for him concerning his sin” (Leviticus 4:26), teaching that the atonement must be effected for the sake of a sin offering, as atonement is effected by the sprinkling of the blood.

אשכחן שנוי קדש, שנוי בעלים מנלן? אמר קרא: ״עליו״⁠ – עליו ולא על חבירו.

The Talmud asks: We found a source for the prohibition against deviation from the type of offering. From where do we derive the prohibition against deviation with regard to the owner? The Talmud answers: The aforementioned verse states: “And the priest should make atonement for him,” indicating that the intent must be for him, and not for another.

אשכחן למצוה, לעכב מנלן? כדאמר רב הונא בריה דרב יהושע: ״חטאת״–״חטאתו״; הכא נמי: ״חטאת״–״חטאתו״.

The Talmud asks: We found a source for the mitzva to sprinkle the blood for the sake of the owner ab initio. From where do we derive that this is indispensable and disqualifies the offering if not fulfilled? The Talmud answers: It is as Rav Huna, son of Rav Yehoshua, says with regard to the sin offering of a nazirite: Since the verse could have simply stated: Sin offering, but instead stated: “His sin offering” (Numbers 6:16), it is inferred that the offering must be sacrificed for his, the owner’s, sake. Here too, since the verse could have simply stated “sin,” but states “his sin,” one infers that if the blood of the sin offering is not sprinkled for the sake of its owner, it is disqualified.
