Nidah 63

1) Rav Papa thought, that when the Beraisa says about Rok Tapal 'Kol she'Lo Ta'am Midi mi'ba'Erev', it means that he did not eat the day before either.

(a) Why did Rava reject that explanation outright?

(b) What then, *does* the Beraisa mean?

According to Rebbi Yochanan, it is only Rok Tapal, if one did not eat after midnight, but one also slept.
(c) How does he explain Seifa of the Beraisa which says that *'Yashan Kol ha'Yom, Ein Zeh Rok Tapal*, Niy'ar Kol ha'Layla, Harei Zeh Rok Tapal'?
(a) How do we describe 'Misnamnem'?

(b) Besides sleeping and not eating, which other condition is required before spittle can be considered Rok Tapal?

3) The Tana of our Mishnah requires that the Gerisin should be chewed. The Gemara tries to bring a proof from here for Resh Lakish.
(a) What does Resh Lakish say?

(b) How does the Gemara reject this proof?

(c) What does Rebi Yehudah say with regard to Mei Gerisin, and why does our Mishnah then not go like Rebbi Yehudah?

(d) How do we know that 'Over' means to go in front (two sources)?

(a) For how long must the urine be 'sour' for it to be included in the Samemanim?

(b) What are the four points which the Tana leaves obscure regarding the details of the urine mentioned in our Mishnah?

(c) Which Sha'aleh remains unanswered with regard to the three rubbings that each of the seven Samemanim requires?

One Beraisa writes 'Hikdim Sheni'im la'Rishonim (e.g. he first washed the stain with Neser, Buris, Kemunya and Ashlag, and then with Rok Tapal, Mei Gerisin and Mei Raglayim), Sheni'im Alu Lo, Rishonim Lo Alu Lo'. Another Beraisa says 'Rishonim Alu Lo, Sheni'im Lo Alu Lo'.
(d) How do we reconcile the two Beraisos?
(a) What is the advantage of Dayah Sha'atah?

(b) The following are included in the category known as Vestos ha'Guf. What do they mean?

1. Mefahekes; 2. Me'ateshes; 3. Chosheshes be'Fi Kereisa, u've'Shipulei Mei'eha; 4. ke'Min Tzemarmaros Ochzin Osah; 5. Shofa'as.
(c) How many times fixes a Veses?
6) The Tana has already taught before (on Daf Beis) that by a woman with a Veses we say Dayah Sha'atah.
So why does he need to repeat it here?

Answers to questions



(a) Which four other cases of Vestos ha'Guf does 've'Chol ka'Yotze Vo come to include?
Shmuel says 'le'Yamim Shenayim, le'Vestos Achas.
(b) What does he mean, and like which Tana does he hold?

(c) Then why does our Mishnah require three sightings for a Kevi'us Veses?

8) If a woman who is used to seeing blood every fifteen days after her Tevilah, changes to the twentieth, b
If this happens three times, then the twentieth becomes her new Veses, and the fifteenth day, permitted.
(a) According to Rav Yehudah Amar Shmuel, who is the author of this statement, and why?

(b) Why does he not say more simply, that the author is Rabban Shimon ben Gamliel?

(c) What will the Chachamim say here and - who is the Chachamim?

(a) With reference to Vestos ha'Guf, what is the difference whether the woman sees at the beginning of the Veses or at the end?
If a woman generally sees blood during the sixth hour of every twentieth day, when is she forbidden ...
(b) ... according to Rebbi Yehudah?

(c) ... according to Rebbi Yossi?

In our Mishnah, Rebbi Yehudah forbids the entire day after the Ha'netz ha'Chamah on which she usually sees; in a Beraisa, he forbids the previous night.
(d) How do we resolve this apparent discrepancy in Rebbi Yehudah?
10) We learn from "ve'Hizartem es Benei Yisrael mi'Tum'asam ... ve'ha'Davah be'Nidasah", that it is a Mitzvah for a man to separate from his wife close to her Veses; and Rava explains this to mean one Onah.
(a) What does he mean by this, the Onah on which she sees, or the entire Onah before that?

(b) Why does Rava also find it necessary to rule like Rebbi Yehudah above (in question 9b)?

(c) Now that he does rule like Rebbi Yehudah, why does he need to issue this latter ruling?

11) If a woman changes her Veses - on two consecutive occasions - from the fifteenth to the twentieth, does she need to take the following fifteenth into account?
