TOSFOS DH V'HADAR
תוספות ד"ה והדר
(SUMMARY: Tosfos explains why our Gemara's inclusion is necessary.)
וא"ת דבפ' כל שעה (פסחים כד:) פשיט מהך משנה דכל איסורים שבתורה אין לוקין עליהם אלא כדרך הנאתן והכא קאמר משום דגמר לה מבכורים
Question: In Pesachim (24b), the Gemara extrapolates from this Mishnah that one only receives lashes due to transgressing Torah prohibitions if he benefited from them in a normal fashion. Yet our Gemara derives this from Bikurim!
וי"ל דרבוי דהכא צריכי דלא נימא זיעה בעלמא הוא
Answer: Our Gemara's inclusion is required in order that one should not say that this is considered mere "sweat" (instead of being like the fruit itself).
TOSFOS DH MARTIKA
תוספות ד"ה מרטקא
(SUMMARY: Rashi and Tosfos argue regarding the definition of Martika.)
פי' ר"ח בשר מת וכן נראה לר"ת
Explanation #1: Rabeinu Chananel explains this is referring to flesh of a dead person, as does Rabeinu Tam.
ולא כפי' הקונטרס שפי' גידי הצואר
Explanation #2: This is unlike Rashi who explains this refers to the sinews of the neck.
מדאמרינן פרק כל הפסולים (זבחים דף לה.) פגל באלל נתפגלה מוראה פגל במוראה לא נתפגלה אלל ובעוף אין גידי צואר קשין ומוראה לא שייך אלא בעוף
Proof: This is apparent from the Gemara in Zevachim (35a) that says that if a person had a thought of Pigul regarding the Alal of a bird sacrifice, its gizzard also becomes Pigul. If he had a thought of Pigul regarding a gizzard, the Alal does not become Pigul. A bird does not have hard sinews in its neck, and a gizzard is only in a bird. (In the Tosfos ha'Rosh from Mossad ha'Rav Kook note 158 they explain the proof of Tosfos. If an Alal is a Martika and Martika is hard sinews, there must not be a Martika in a bird as there are no hard sinews in a bird. Accordingly, it is nonsensical to say that the statement, "An Alal does not cause Pigul and does not become Pigul" (see Zevachim 35b) is specifically regarding an animal and not a bird, as a bird does not even have an Alal! It therefore must be that Rashi's explanation is incorrect.)
ולמאן דמפרש בשר שפלטתו סכין לא קשה ליה מהתם
Implied Question: There is no difficulty from the Gemara in Zevachim (ibid.) on the opinion who says that this refers to meat that was taken off with the skin during the skinning. (The Gemara there does not seem to be discussing such meat!)
דהא אמרי' בסמוך דלכ"ע מרטקא נמי הוי אלל
Answer: This is as we say later that everyone agrees that Martika can also be the Alal.
TOSFOS DH REBBI YEHUDAH
תוספות ד"ה ר' יהודה
(SUMMARY: Tosfos explains why Rebbi Yehudah did not say simply that it is impure with the impurity of Neveilos.)
הא דלא קאמר מטמא טומאת נבלות
Implied Question: Rebbi Yehudah did not say that it is impure with the impurity of Neveilos. (Why not?)
דלא תימא מדרבנן להכי קאמר חייבין עליו
Answer: This is in order that one should not think he is saying this according to Rabbinic law. This is why he said, "one is liable for it."
TOSFOS DH V'HU
תוספות ד"ה והוא
(SUMMARY: Tosfos explains that Rebbi Yehudah's statement in the Mishnah is only referring to impurity.)
תימה מה שייכא מחשבה לאיסור דגבי טומאה שייך לחלק דאי מבטל ליה עץ בעלמא הוא אבל משום דבטליה לא משתרי באכילה
Question: This is difficult. How does a thought cause prohibition? Regarding impurity it is possible to say that if he nullifies it, it is considered like wood. However, nullifying it will not cause it to be permitted for consumption!
לכך נראה דחייבין עליו לא מיירי לענין אכילה דלא צריך כנסו אלא לענין אם נכנס למקדש כמו שפי' בקונטרס בלשון אחר
Answer: It therefore appears that when the Mishnah (117b) says that he is liable for it, it is not regarding eating it which would not require him to gather it together. Rather, it is regarding if he enters the Mikdash after becoming impure from it, as Rashi explains in his alternative text.
והא דלא נקט טמא
Implied Question: The Mishnah does not state "he is impure." (Why doesn't the Mishnah say this if this is the main point of the statement?)
דלא תימא מדרבנן כדפי'
Answer: This is in order that one should not think he is impure according to Rabbinic law, as I explained.
וכן נראה דאי אאכילה הא כיון דאכלו אין לך כינוס גדול מזה
Proof: This appears correct, as if it is referring to eating, once he eats it there is no greater gathering than this! (Accordingly, the Mishnah should not have to specify "gathering" if it is discussing eating, and must only be referring to impurity.)
TOSFOS DH V'REBBI YOCHANAN
תוספות ד"ה ורבי יוחנן
(SUMMARY: Tosfos explains the argument between Rebbi Yochanan and Reish Lakish.)
ולאו בכה"ג דהוי שומר
Explanation: This does not mean that it is a Shomer.
דא"כ מ"ט דר"ל עור ועצם מצטרפים משום שומר וצירוף שומר מקראי דרשינן לעיל (דף קיח.)
Proof: If it did, what would be the reasoning of Reish Lakish? Skin and bone combines to be a Shomer, and the fact that things combine to become a Shomer is derived from the Pasuk as stated earlier (18a)!
אלא מיירי כגון שיש בראשו כזית בשר דאע"ג דלא הוי שומר מצטרף דראוי הוא שיאכל אגב בשר וריש לקיש סבר דלא מצטרף דאין ראוי לאכילה דעץ בעלמא הוא
Explanation: Rather, the case is where there is a Kzayis of meat at the head of it. Even though it is not a Shomer it combines, as it is fitting to be eaten together with the meat. Reish Lakish understands that it does not combine with the meat, as it itself is not fit to be eaten as it is like wood.
TOSFOS DH HACHI GARSINAN
תוספות ד"ה ה"ג
(SUMMARY: Tosfos explains that Rav Papa is explaining our Mishnah.)
ולא גרסינן בה קרנים
Text: We do not have the text, "horns" (in the Mishnah in Taharos).
וקרנים דמפרש בה רב פפא בסמוך
Implied Question: Rav Papa explains the word "horns" later. (Isn't this referring to the Mishnah in Taharos?)
אמתני' דהכא קאי
Answer: He is referring to our Mishnah.

TOSFOS DH HO'IL
תוספות ד"ה הואיל
(SUMMARY: Rashi and Tosfos argue regarding the context of Chizkiyah's statement.)
פ"ה שיכול לחותכה בחתיכות קטנות פחותות מכזית בעודה מפרכסת
Explanation #1: Rashi explains that he can cut it into little pieces that are less than a Kzayis when it is in its death throes.
ולא היה צריך לפרש כן
Implied Question: He did not have to say this.
אלא אפילו חתיכות גדולות ובלבד שלא יהיו אברים דבשר מן החי לא מטמא כדאמר לקמן בפרקין (דף קכח:) ועל הנבלה הוא דקאמר צריך שישייר ויעמיד על (טומאה) פחות מכזית
Explanation #2: Rather, he can even cut it into big pieces, as long as they should not be whole limbs. This is because meat from a live animal does not become impure, as stated later (128b). Chizkiyah is only stating regarding Neveilah that the piece has to be less than a Kzayis.
TOSFOS DH U'LIHAMIDAH
תוספות ד"ה ולהעמידה
(SUMMARY: Tosfos explains why this piece of meat is not considered to eventually have a stringent form of impurity.)
וא"ת השתא נמי סופו לטמא טומאה חמורה כיון דאילו מצטרף ליה עם חצי זית אחר מטמא כדאמר פ' דם שחיטה (כריתות דף כא.)
Question: This is something that can end up having a stringent form of impurity, as if it would combine with another half Kzayis it would be impure, as stated in Kerisus (21a)!
וי"ל דהתם בנבלה שמתה לגמרי מהני צירוף אבל הכא הואיל וסופו לטמא טומאה חמורה אחר שתמות שיצרפנה לכזית לא אמרי'
Answer: The Gemara in Kerisus (ibid.) is referring to a dead Neveilah, and in such a case combining would work. However, in our case we do not say that it will eventually be able to have a stringent form of impurity just because it can do so by combining with another half a Kzayis after it dies.
TOSFOS DH U'MI
תוספות ד"ה ומי
(SUMMARY: Tosfos explains that the Gemara prefers to ask that Chizkiyah is contradicting himself than ask a question from a Mishnah.)
דחזקיה אחזקיה ניחא ליה לאקשויי אע"ג דהוי מצי לאקשויי בלאו הכי ממתניתין דקתני אבל לא טומאת נבילות אחזקיה דאמר מתה היא
Explanation: The Gemara would rather ask that Chizkiyah is contradicting himself than ask a question on his position that the animal is considered dead from the Mishnah that says, "However, not impurity of Neveilos."
TOSFOS DH NACHARAH
תוספות ד"ה נחרה
(SUMMARY: Tosfos explains that the Halachah here is the same as in the case where he slaughtered one Siman.)
היינו נמי אין מטמאה טומאת אוכלין דקתני גבי שחט בה סימן אחד
Explanation: This means that it does not even become impure as does food, just like the previous case where he slaughtered one Siman.
אלא משום דלא עשה בה דרך שחיטה נקט האי לישנא כלומר נחרה והתם פשוט דאין בה טומאה כלל כיון דלא עבד כלל דרך שחיטה
Explanation (cont.): It only used this terminology, "that he tore it apart" because he did not do an action of slaughtering. In such a case it is obvious that it does not have any impurity, since he did not do anything is a manner of slaughtering.
TOSFOS DH V'OVED KOCHAVIM
תוספות ד"ה ועובד כוכבים
(SUMMARY: Tosfos explains why the Beraisa discussed a Nochri who "slaughters" for a Jew.)
רבותא נקט דאפי' לישראל דבשחיטה תליא מילתא אבר הפורש ממנה כפורש מן החי
Explanation: This is including that even for a Jew, where these Halachos depend on slaughtering animals, a limb that leaves the animal is like a limb that comes off of a live animal.
TOSFOS DH ABAYE
תוספות ד"ה אביי
(SUMMARY: Rashi and Tosfos argue regarding Abaye's reasoning.)
וטעמא משום דכי חיה היא לכל דבריה ולכך רובעה חייב ומ"מ מטמא טומאת אוכלין כיון דבת אכילה היא
Explanation #1: The reason is that it is generally considered alive, and therefore one who has relations with it is liable. However, it receives the impurity of food because it can be eaten.
ובקונט' פירש משום דלחומרא
Explanation #2: Rashi says Abaye is merely being stringent in each question.
ותימה א /אי/ ספיקא היא אמאי רובעה חייב
Question: This is difficult, as if the Halachah is unclear, how can he say that someone who has relations with it is liable?
