Nidah 30


(a) Only twenty-eight days (seven times the first week, fourteen, the second, and seven the third) out of the above-mentioned days require Tevilah according to Beis Hillel, so how does he arrive at thirty-five?

(b) What does the Gemara mean when it asks why ten weeks are necessary, eight and a half will suffice?

(c) How does the Gemara answer that question?

(d) And what does the Gemara mean when it asks why the Beraisa does not mention the Tevilas Zavah, and what is the answer?

(a) According to Beis Shamai, who does include the Tevilos after Tashmish, why does the Beraisa omit the Tevilos Zavah?

(b) But surely Beis Shamai did include the Tevilos of a Yoledes be'Zov?

(c) Why does the Beraisa not include the Tevilah of the last day of the first week, which may be the last of the seven clean days, if she was a Yoledes be'Zov, who was able to count seven clean days from the moment that she returned which?

(d) Which question on Beis Hillel does this answer also resolve?

(a) Why does the Beraisa not include in the list the first day after she arrives, when she is obligated to Tovel, because she may be a Shomeres Yom ke'Neged Yom (a Zavah Ketanah)?
In the opinion of Rebbi Yossi b'Rebbi Yehudah, she only needs to Tovel once at the end.
(b) In which point does he argue with Beis Hillel and Beis Shamai?
(a) What is the difference between a woman who miscarries after forty days and one who miscarries after forty-one days?

(b) Why does Rebbi Yishmael b'Rebbi Yossi disagree with the Tana Kama regarding a miscarriage after forty-one days, and what is his reason, and what does he hold - regarding a woman who miscarries on the forty-first day?

(c) Why does the Mishnah need to mention that she must sit for a boy, since both the days of Tum'ah and the days of Taharah for a boy are absorbed in the days for a girl.
