Zevachim Daf 71 זבחים דַף 71

The eighth Perek begins: כל הזבחים שנתערבו בחטאות המתות – all korbanos which became mixed with חטאות which are left to die (e.g., its owner died), or with שור נסקל – a cow condemned to stoning (which are forbidden in benefit), אפילו אחת בריבוא – even if one [prohibited animal] was mixed in ten thousand [korbanos], ימותו כולן – they are all left to die. If a korban became mixed with an animal permitted in benefit, but disqualified as a korban, such as if an aveirah was performed with it, meaning: שהמית את האדם ע"פ עד א' – it killed a person according to one person’s testimony, או ע"פ הבעלים – or according to its owner’s testimony (both testimonies are insufficient to kill the animal, but disqualify it as a korban), or an animal which had relations with a person, במוקצה ונעבד – or [an animal] designated for idolatrous service, or one which was worshipped, or an animal used for a זונה’s payment or exchanged for a dog, כלאים – a crossbreed, a טריפה, or an animal born by Caesarian section, ירעו עד שיסתאבו – they are all left to graze until they develop a מום, וימכרו – and are sold, ויביא בדמי היפה שבהן מאותו המין – and with the value of the most expensive among them, he should bring the same type of korban.

The Mishnah continues: if korbanos became mixed with unblemished chullin animals, the chullin animals are sold to those requiring the same type of korban. קדשים בקדשים מין במינו – If korbanos became mixed with other korbanos of the same type, [זה יקרב לשם מי שהוא וזה] יקרב לשם מי שהוא – each should be sacrificed for the sake of whoever is the true owner. If korbanos became mixed with korbanos of a different type, and cannot be sacrificed because their blood מתנות are different (e.g., a שלמים became mixed with a חטאת), they are left to graze until they develop a מום, and since we do not know which korban type was the more expensive one, he must bring another of each type of korban with the more expensive animal’s value, ויפסיד המותר מביתו – and lose the difference from his own [funds]. If korbanos became mixed with a בכור or מעשר (which cannot be redeemed), they are left to graze and develop a מום, and all these animals are eaten with the restrictions of בכור and מעשר korbanos (i.e., that cannot be shechted or sold publicly in a degrading way).

The Gemara asks that a Mishnah in Temurah already taught this law: כל האסורין לגבי מזבח אוסרין בכל שהן – all that are prohibited for sacrifice on the מזבח prohibit any group into which they are mixed with any amount (i.e., are never nullified), for example, a רובע or נרבע!? Rav Shimi answers that the Mishnah in Temurah only teaches that about animals which all become prohibited לגבוה – for the Mikdash’s use as korbanos (but are all permitted in benefit), and our Mishnah adds that animals forbidden in benefit prohibit the entire group להדיוט – for common use. On the other hand, our Mishnah only teaches that animals forbidden in benefit are never nullified, and the Mishnah in Temurah adds that even those permitted in benefit (a more lenient prohibition) are not nullified. Although our Mishnah also discusses animals permitted in benefit, it does not state that it would never be nullified in a greater amount. Still, our Mishnah’s ruling about permitted animals is necessary to teach תקנתא – its remedy (that they should graze until they can be redeemed).
