Daf Yomi for Women - Hadran

Rav Hamnuna states in the name of Rabbi Shimon that the prohibition of oto v'et beno does not apply to consecrated animals (kodashim). This is based on Rabbi Shimon's principle that an invalid slaughter is not halakhically considered a slaughter (shechita she'eina reuya lo shema shechita), and since the meat of a sacrifice is not permitted for consumption until its blood is sprinkled, the slaughter itself is initially unfit. Rava challenges this using a text discussing various combinations of slaughtering consecutive sacrifices inside or outside the Temple courtyard (bifnim or bachutz), tracing the respective liabilities of karet and negative...

After the Gemara establishes the root of the debate between Rabbi Eliezer and the Rabbis regarding a koy, Rav Papa clarifies the specific type of koy they dispute concerning the prohibition of slaughtering a parent and its offspring on the same day (oto v'et beno) and the distribution of priestly gifts (matnot kehuna). He also explains that the Mishna's ruling—which prohibits slaughtering a koy on Yom Tov due to the uncertainty of whether its blood requires covering (kisuy hadam)—aligns specifically with the Rabbis' position. The Gemara then introduces three other opinions regarding the exac...

The Gemara discusses the prohibition of slaughtering an animal and its offspring on the same day (oto v'et beno). The Mishna presents various permutations of non-sacred animals (chullin) and consecrated sacrifices slaughtered either inside or outside the Temple courtyard, outlining the respective punishments incurred and the halakhic status of the meat.

A braita derives from biblical verses that this prohibition applies to consecrated animals, and the Gemara subsequently demonstrates that it applies to non-consecrated animals as well. Since the laws of oto v'et beno are learned from consecrated animals, the Gemara questions why the prohibition also applies...

If a bone is broken but the majority of its width is surrounded by flesh and skin, the animal is not considered a treifa—even if the break is above the knee joint (arkuva)—and the limb is not considered a limb severed from a living animal (ever min hachai). A case came before Rava where the bone was covered by a majority of "flesh" only when including soft sinews. Rava initially permitted this based on Rabbi Yochanan's opinion that soft sinews are considered like meat for fulfilling the mitzva of eating the Pesach sacrifice. However, Rav Papa challenged this...

The Gemara cites two conflicting statements of Rav regarding a hanging limb of an animal. In one statement, Rav rules that eating this limb incurs lashes, while in the other, he rules it does not. Rav Yosef resolves this contradiction: if the animal dies naturally, death causes legal detachment (oseh nipul), retroactively defining the hanging limb as ever min hachai (a limb from a living animal) which incurs lashes for one who eats it. Conversely, if the animal is slaughtered, slaughter does not cause legal detachment (eino oseh nipul), meaning the limb is not treated as a separate forbidden...

The Gemara presents biblical derivations establishing that undomesticated animals (chaya) are included in the legal category of domesticated animals (behema) and vice versa. This crossover applies to kosher signs, crossbreeding laws, sacrificial impurities, and miscarriages.

The Mishna rules that if a fetus dies in utero and a midwife reaches inside and touches it, the midwife contracts seven-day corpse impurity, while the mother remains pure until the fetus emerges.

Rabba establishes that just as absorbed impurity (tuma belua) does not pass on impurity, absorbed purity (tahara beluah cannot become impure. The Gemara seeks biblical and logical s...

The Mishna explains at what stage a delivery is considered a birth (even for a stillborn animal) to determine whether it exempts subsequent offspring from firstborn status, particularly in the case of a difficult birth where the fetus is extracted in pieces.

Rav Huna and Raba disagree regarding when the majority of the animal emerges: does the sanctity of the firstborn apply retroactively or only from that moment onward? The Gemara presents two cases demonstrating the practical ramifications of this dispute. A difficulty is raised against Rav Huna's position from our Mishna, but it is ultimately resolved...

Different rabbis raise a total of four questions regarding various scenarios in which a ben pekua (a fetus of an animal whose mother was slaughtered) previously had a limb or limbs leave the womb.

The Gemara investigates the biblical source for the Mishna's ruling that parts of a fetus that were severed but remained inside the mother at the time of slaughter are permitted to be eaten, offering two different suggested sources.

A fetus that is inside the mother at the time of her slaughter is permitted without needing its own slaughter. If a limb of the fetus emerges before the mother is slaughtered, that limb is forbidden. However, if the limb is pulled back inside before the mother's slaughter, its status is subject to a dispute: Rav holds that the limb remains forbidden, while Rabbi Yochanan rules that it is permitted. Three difficulties are raised against Rav's position—one from our Mishna and two from other tannaitic sources—and all are ultimately resolved in the same mann...

The Gemara details the hermeneutical methods used to permit drinking water from pits, ditches, or caves without concern for finless and scaleless creatures. Regarding water in vessels, the braita states that its exemption is explicit in one verse and implicit in another. One version holds that the permission for vessels is explicit, derived from the verse explaining that fish in seas and streams must have fins and scales to be eaten (Vayikra 11:9), meaning that anything in vessels is permitted. The second version reverses this, arguing that the explicit source is the subsequent verse (Vayikra 11:10-11) which forbids fish in...

The braita from the school of Rav and the braita from the school of Rabbi Yishmael disagree about whether a grasshopper with a long head is kosher. The source of the dispute stems from their application of different hermeneutical principles to the verse. Further on, the Gemara raises two difficulties against other parts of the braita of the school of Rabbi Yishmael and resolves them.

The definitive kosher signs of fish are fins and scales. A fish that lacks scales in its youth but will grow them later, or a fish that has scales but sheds them...

What are the signs of kosher grasshoppers? 

One may purchase eggs from a non-Jew if the seller explicitly specifies that they come from a particular kosher species. The Gemara asks why we cannot simply rely on the physical diagnostic signs of kosher eggs, which are: being pointed on one end and rounded on the other, and having the yolk (chalmon) on the inside with the albumen (chelbon, or white) on the outside. The Gemara explains that these signs alone are insufficient because certain non-kosher species (such as the crow) lay eggs that mimic these exact characteristics.

Regarding blood found in an egg, the halakhic...

The Gemara continues to enumerate various species of birds, identifying which are kosher and which are not, while providing helpful mnemonics to remember their status. A debate is cited regarding whether there are 23 or 24 non-kosher bird species in total; both opinions require structural explanations as to how they arrived at their respective counts, given that there are 20 species listed in Vayikra and 21 listed in Devarim.

One can purchase eggs from a non-Jew, provided the non-Jew identifies the specific bird they came from, and that species is known to be kosher.

There is a dispute between Rav Nachman and Ameimar whether a bird possessing a single sign can be permitted if one is not expert in identifying the peres and ozniyah. Rav Nachman does not permit it, but Ameimar rules that any bird with a single sign is permitted, provided it is not known to be a predator (doreis), as there is no concern regarding the peres and ozniyah since they do not inhabit populated areas.

The characteristics of specific birds are defined, such as the white swallow (concerning which Rabbi Eliezer and the Sages disagree) and the...

The Mishna states that the four physiological signs of a kosher bird are not explicitly detailed in the Torah, but are instead established by the Sages. The Gemara challenges this assertion based on a braita, which indicates that these kosher indicators are actually derived through a comparison of the anatomical details of each type of bird—specifically evaluating the characteristics of the nesher (griffin vulture), which is listed as non-kosher, against those of the tor (turtledove), which is known to be kosher due to its role in sacrificial offerings. Abaye resolves this difficulty by explaining that the analytical comparison of...

There is a series of theological debates between Rabbi Yehoshua ben Hananya and the Roman emperor, which demonstrate the sublimity of God through man's inability to look directly at the sun or to sustain the natural armies that serve God. A similar discussion with the emperor's daughter, who scoffed at the providence of God in the world, leads to a punishment of leprosy being inflicted upon her, emphasizing the principle that God's presence is indirectly guiding the world.

Rav Yehuda discusses the physical dangers of consuming chiltit (asafoetida), particularly on an empty stomach, which Rav Yosef expands upon by listing other hazardous foods consumed on an empty stomach.

The Gemara notes that Rav initially permitted an animal whose legs had been severed because he verified that the convergence of sinews (tzumat hagidim) remained intact. Shmuel, however, cautioned him that the severing might have been caused by a venomous snakebite, rendering the animal forbidden due to mortal danger. Shmuel proposed a specific diagnostic test to detect the presence of venom; upon execution, the test confirmed Shmuel's...

Conflicting traditions existed regarding Rav's ruling in the case of a dislocated femur in a bird. Ultimately, the analysis indicates that Rav permitted such a bird, except in regions where the prevailing custom was to forbid it. However, after presenting various differing opinions regarding this issue, which leaned primarily toward permissibility, the Gemara brings an incident demonstrating that the widespread, accepted custom was indeed to forbid this condition; consequently, the practical halakha is established to be stringent in accordance with this accepted communal custom.

Rav Huna defines a treifa as an animal that cannot survive for more th...

The Mishna enumerates all the physical defects that cause a bird to be rendered a treifa, as well as those that leave it kosher. If a weasel (chulda) attacks a bird in an area where the brain membrane could have been perforated, the bird is considered a treifa. There are, however, different tests one can perform to ascertain whether the membrane was actually punctured, and the Gemara suggests various methods for this inspection. Conversely, in the case of birds that live in the water, a broken skull creates an absolute presumption that the brain membrane was punctured, meaning that...

Rava raises several difficulties against Rav Nachman's position that the term "until" implies up to but not including the final value. However, it concludes that the exact meaning depends on the specific context as one must always rule stringently with requisite amounts (shiurim), with the sole exception of a single requisite amount regarding the laws of niddah.

Regarding some of the cases enumerated as kosher in the Mishna (if the spleen and kidneys are removed, or the lungs shrivel up out of fear), the Sages qualify and restrict the specific parameters under which the...

Rav Bibi bar Abaye rules that although a standard hole in the windpipe requires the size of an issar (a coin), its clawing measurement (of redness) is a minimal amount, because the predator's venom burns and consumes the tissue continuously. Regarding the scope of the inspection required due to concern for venom, Rav Nachman testifies in the name of Rav that one must inspect from the base of the brain to the thigh, and not only adjacent to the intestines (as some hold). In an interesting story, Rabbi Yochanan defends the supreme authority of Rav against the queries of...

A cat or a weasel (chulda) renders a bird a treifa through clawing (derisa), whereas only a cat can do so for small cattle such as young goats and lambs. Other predatory birds besides those explicitly listed in the Mishna can also render other birds a treifa by clawing, but only when targeting birds smaller than themselves, while a hawk (netz) can do so even to birds of its own size. According to an alternate version, ordinary predatory birds can claw birds of their own size or smaller, whereas the hawk can even render birds larger than itself a...

The Gemara discusses what other protective materials a bird could fall upon that would successfully cushion its impact and prevent it from being rendered a treifa. Relatedly, if a bird's wings become stuck to each other or to its body, a debate arises as to whether or not the bird will become a treifa upon falling, as its ability to break the fall is compromised. Two opinions are brought regarding the scope of this debate - specifically, whether the dispute applies to a case where only one wing is glued or if it is restricted to a case where...

A braita establishes the laws of a needle found in the thickness of the beit hakosot, ruling that a single-sided penetration is kosher while a complete perforation renders the animal a treifa. The presence of a drop of blood or a scab determines if the injury occurred before shechita.

Internal organ crushing (risuk evarim) caused by falls is a treifa according to the Mishna. Rav Huna rules that an animal left on a roof and subsequently found below is not assumed to have crushed organs, a principle the Gemara applies to a practical case involving Ravina's goat...

Rav Nachman identifies two types of fat on the stomach: bar chimtza, which can effectively seal a perforation, and chimtza, which cannot. To clarify which specific fat constitutes bar chimtza, the Gemara cites an independent statement by Rav Nachman regarding a halakhic dispute between the Sages of the Land of Israel and those of the Diaspora.

Rabban Shimon ben Gamliel rules that if internal mucus seals a perforation in the intestines, the animal is not a treifa. Rabbi Yochanan is cited as ruling in accordance with Rabban Shimon ben Gamliel on this issue and on an unrelated...

The Gemara explores the halakhic distinction between finding a needle embedded within the wall of the beit hakosot (reticulum) versus inside the liver. In the liver, the orientation of the needle indicates its trajectory, allowing the Sages to determine whether it caused a disqualifying perforation. Conversely, in the beit hakosot, the orientation is inconclusive, as the movement of food within the stomach could have pushed the needle out.

When a perforation is discovered, it may be uncertain whether the puncture occurred before or after the shechita (ritual slaughter). The Sages present differing opinions regarding whether it can...

The Gemara discusses additional cases of treifot, alongside several real-life incidents brought before the Sages, detailing how they ruled - or, in certain instances, declined to render a definitive decision.

The first issue concerns a lung that has become attached to the ribs. Because the lesion causing the adhesion might have originated in the chest wall rather than the lung itself, the animal might not be a treifa. The Sages dispute whether this condition is permissible and outline diagnostic methods to determine the source of the underlying wound.

Regarding cysts or fluid-filled blisters on the...

Rava establishes further laws regarding physical anomalies that render a lung a treifa. If cysts appear on the lung, a single cyst does not disqualify the animal, whereas two distinct cysts render it a treifa. Rava provides a method to inspect an ambiguous cyst to determine whether it is a single divided structure or two separate entities. Regarding the lobes of the lung - which normally consist of three on the right and two on the left – Rava rules that deviations from this norm disqualify the animal. Meriemar permitted an extra lobe provided it is perfectly aligned with the na...

What is the minimal remnant required to remain of the liver to keep the animal kosher when it is damaged or partially missing? Although our Mishna implies that any minimal amount is sufficient, another Mishna explicitly requires an olive-bulk. Rav Yosef resolves the contradiction by explaining that each Mishna reflects a different Tannaitic position. The established halakha dictates that a size of an olive-bulk is required, and the Amoraim dispute whether this piece must remain specifically where the gallbladder is located, or where the liver attaches to its lifelines; Rav Papa rules that an olive-bulk is required in both...

Under what conditions do perforations, cracks, or missing fragments in the windpipe render an animal or bird a treifa? How do perforations add up to the requisite amount needed to determine the animal is a treifa? The Sages delineate specific measurements for damage to the windpipe, depending on the type of perforation. For a crack along its length, the organ remains kosher provided that a little remains intact at the beginning and the end of the windpipe.

The Sages discuss the precise anatomical boundaries of several vital organs, as these definitions carry significant halakhic w...

What are the primary categories of treifot? Ulla states that eight categories that were transmitted as halakha to Moshe from Sinai: perforated (nekuva), severed (pesuka), removed (netula), deficient (chasura), torn (kru'a), clawed (drusa), fallen (nefula), and broken (shevura). Chiya bar Rav said there are eight cases in the category of perforated, and this excludes the gall bladder, which is considered a treifa only by Rabbi Yosi b'Rabbi Yehuda. However, Rabbi Yitzchak bar Yosef said in the name of Rabbi Yochanan that the ruling is like Rabbi Yosi b'Rabbi Yehuda. He brings a proof for Rabbi Yosi's position from a...
