Daf 23 — Bechoros 23 Summary

Bechoros 23 – Good Morning Raboisai Chazarah – Tzir and Hashakah The Daf continues the Sugya of Tzir – fish brine containing water. If the mixture contains: • A majority of water, Hashakah with Mikvah water can make the water Tahor. • A majority of Tzir, the minority water becomes Batel to the Tzir, which itself is not one of the seven liquids that are Mekabel Tumah. The question is: What happens if more water is later added? Can the original water that became Batel “wake up” and regain its Tumah Terumah Temeiah Mixed into Chullin The Gemara brings a case where: • One Se'ah of Terumah Temeiah falls into one hundred Se'ah of Chullin. Rebbi Eliezer says: • Remove one Se'ah and treat it as the Terumah. The Chachamim say: • The Terumah becomes Batel. The Kohen's financial loss can still be paid for, but the mixture itself may be eaten. How May the Mixture Be Eaten? The mixture must be handled so that it does not become Tamei. It may therefore be eaten: • Dry, • Roasted, • Kneaded with fruit juice, • Or divided into portions smaller than a Kebeitzah. The key is to avoid introducing the conditions that would allow the food to become Mekabel Tumah. Can Something That Became Batel Return? The Dormant Tumah The Gemara now develops yesterday's central question. Suppose a small amount of Tamei material becomes: • Batel B'Rov. It has not physically disappeared. Its Halachic status has simply been neutralized within the majority. Can a later change cause that Tumah to become significant again? Adding More Tamei Chullin Suppose: • One Tamei part is Batel inside a larger amount of Tahor Chullin. Later: • More Tamei Chullin is added. The newly added Tumah can combine with: • The original Tamei part that had become Batel. Together they may now form: • The majority. This demonstrates the concept that something which became Batel can later regain significance. Abaye – Tumah Can Awaken Tumah Abaye distinguishes this case from the Tzir. In the Terumah case: • Tamei material is being added to other Tamei material. Therefore: • Im Tumah Orerah Tumah – Tumah can awaken Tumah. But the Tzir case is different. There: • Tahor water is being added. Abaye asks: Where do we see that Taharah can awaken Tumah? This is the key challenge. Parah Adumah Ashes Parah Adumah Mixed with Ordinary Ash The Gemara brings ashes of: • Parah Adumah, mixed with: • Ordinary ash. If the Parah Adumah ash is the majority: • We follow the majority and its status remains significant. If ordinary ash is the majority: • The Parah Adumah ash becomes Batel. This again demonstrates the power of: • Rov. Maga – Touching the Mixture If the Parah Adumah ash is the minority and a person touches the mixture: • We assume he touched the majority ordinary ash. Therefore: • The minority does not create Tumah through Maga. Even if he touches the mixture repeatedly: Each individual contact is judged according to the Rov present at that moment. But What About Masa? The Gemara asks an important question: Touching is understandable. But what if he: • Lifts the entire mixture? Now he has definitely carried: • The Parah Adumah ash together with everything else. If the minority Tumah still physically exists and is merely Batel: Why shouldn't it convey Tumah through Masa? The Gemara accepts that this is indeed different. Neveilah Mixed with Shechutah Neveilah Becomes Batel A similar case involves: • One piece of Neveilah, • Mixed with a majority of properly shechted meat. The Neveilah becomes: • Batel B'Rov. If someone touches one piece: • We follow the Rov and assume he touched the Shechutah. But if he carries: • The entire mixture, the Neveilah is definitely being carried. Therefore, Masa can still create Tumah even where Maga does not. Back to the Chararas Dam Why Doesn't It Give Tumah Through Masa? We now return to the Mishnah from yesterday. An animal gives birth to: • A Chararas Dam – a mass of blood containing remnants of a Vlad. Rebbi Eliezer ben Yaakov says: • It must be buried. • The mother is now exempt from Bechorah. • Yet the Chararas Dam does not convey Tumah. We understood Maga: • The Vlad is Batel in the majority. But now the question returns: When someone carries the entire mass, he is certainly carrying the Vlad. Why isn't he Tamei through Masa? Tumah Seruchah The Gemara answers that this case is different because: • The Vlad has deteriorated and become extremely repulsive. It is no longer normal edible flesh. This introduces the concept of: • Tumah Seruchah – deteriorated or spoiled Tumah. Its physical condition can remove or reduce its ability to convey Tumah. Fit for a Person or a Dog Bar Pada – Tumah Chamurah Bar Pada distinguishes between two levels. For the more severe Tumah associated with carrying: • The Neveilah must still be fit for human consumption. Once it becomes: • Unfit for a person to eat, it no longer conveys this stronger Tumah. Tumah Kalah – Fit for a Dog For the lighter Tumah of touching: • The standard continues for longer. As long as the material is still: • Fit for a dog to eat, it can retain Tumah. Only when it becomes: • Unfit even for a dog, does this Tumah disappear. The level of deterioration therefore matters. Rebbi Yochanan's Approach Rebbi Yochanan does not accept the distinction in exactly the same way. The Gemara discusses flesh that: • Was never fit for human consumption in the first place. That case can be treated differently from ordinary Neveilah which: • Was originally edible, • And only later spoiled. This distinction helps explain the status of the Chararas Dam. Back to Tzir When the Water Reawakens The Gemara returns to Tzir. If Tamei water had previously become: • Batel within the brine, adding enough new water may cause the original water to: • Regain significance. The earlier Bitul does not necessarily mean: • The original water ceased to exist. Its status can potentially return when the proportions change. Fifty - Fifty The Gemara also discusses the exact proportions. Because the Tumah involved with these liquids is: • Rabbinic, the rules concerning Rov and equal quantities become important. A clear majority may be required before: • The Rabbinic Tumah is applied. The difference between fifty - fifty and an actual majority can therefore matter. A New Mishnah – Nursing Proves Maternity An Animal Nursing a Young One The next Mishnah discusses an animal seen: • Nursing a young animal. We assume: • The nursing animal is its mother. We do not normally suspect: • That the offspring belongs to another animal. What we see is accepted as the natural relationship between mother and offspring. The Effect on Bechorah If an animal that was not known to have previously given birth is nursing: • We treat the nursing offspring as its own. Therefore: • This establishes that the mother has now given birth. Likewise, where the nursing offspring itself is the firstborn: • It receives the appropriate Bechor status. We do not avoid Bechorah by claiming: • Perhaps this offspring really belongs to another mother. Rav's Rule for This Perek Halachah Throughout the Perek Rav Nachman says in the name of Rav: • The Halachah follows the rulings throughout this Perek, except: • Where the Mishnah itself records a Machlokes. The Gemara asks: Which particular Mishnah required Rav to teach this rule? Not the Earlier Mishnayos The Gemara considers several possibilities. It cannot simply refer to cases where: • The Mishnah itself already records opposing opinions. Nor is there a need to teach separately that: • The Halachah follows Rebbi Eliezer ben Yaakov, because there is already a famous principle: • Mishnaso Kav V'Naki – his teachings are exceptionally authoritative. The Nursing Mishnah The Gemara concludes that Rav's statement is needed for: • The Mishnah concerning an animal nursing its offspring. Although a Beraisa contains: • A disagreement about this Halachah, the Mishnah itself: • Records the ruling without a dispute. Rav therefore teaches that the Halachah follows our Mishnah. The exception for a Machlokes means: • A Machlokes recorded in the Mishnah itself, not merely a disagreement found elsewhere in a Beraisa. Key Chazarah • Minority Tamei water can become Batel within a majority of Tzir. • The Gemara asks whether something that became Batel can later regain its original status. • Tamei material added later can “awaken” previously Batel Tumah. • Abaye distinguishes between Tumah awakening Tumah and Taharah awakening Tumah. • Parah Adumah ash can become Batel within a majority of ordinary ash. • Maga can follow the Rov because each touch is attributed to the majority. • Masa is different because carrying the whole mixture means the Tamei component was definitely carried. • The same distinction applies to Neveilah mixed with Shechutah. • The Chararas Dam does not convey Tumah through Masa because of its deteriorated condition. • Bar Pada distinguishes between material fit for human consumption and material fit only for a dog. • Adding water to Tzir can potentially cause previously Batel water to regain significance. • An animal nursing a young one is presumed to be its mother. • Rav rules like the Mishnayos throughout the Perek except where the Mishnah itself records a Machlokes. • This rule is particularly needed for the Mishnah concerning the nursing animal, despite a disagreement appearing in a Beraisa.
