Daf Yomi for Women - Hadran

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 (griffi...

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...

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 ...

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 custo...

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 th...

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

Rav Bibi bar Abaye rules that although a standard hole in the windpipe requires the size of an issar (a coin), its clawing

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 haw...

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 ...

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 ...

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 interna...

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 coul...

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 adhesi...

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 Read more
