1) The Beraisa learns all the Dinim of the eleven days from Pesukim.
(a) From where do we know that the three days sighting that make a woman a Zavah must occur outside the days of Nidus?We learn from "O Ki Sazuv", that even if the three sightings do not occur immediately after the termination of her Nidus, but there is one day's break in between, she still becomes a Zavah.
(b) From where do we know that even if she sees Zivus three times, from the fifth day (after the termination of her Nidus), through the tenth, she is still a Zavah Gedolah?2)
(a) From where do we know that if a woman sees on the tenth, the eleventh and twelfth, that she is not a Zavah Gedolah?3) We learn that a Zavah renders her Bo'eil Tamei from the superfluous word "Temei'ah".
(a) What do we learn from the word "Hi"?We learn from "ke'Mishkav Nidasah" that a Zavah, like a Nidah, is Metam'ah Mishkav and Moshav.
(c) What do we learn from "Kol Yemei" written there?4) From 'Yihye Lah" we learn, that if she sees once during the days of Zivus, she must watch one clean day.
(a) What would have caused us to think that two sightings during her days of Zivus would require *seven* clean days?5)
(a) Seeing as all the Dinim of Zivus derive from Pesukim, why does the Beraisa on the previous Amud cite their source as 'Halachah le'Moshe mi'Sinai'?6) What do we learn from the Pasuk in Chavakuk "Halichos Olam Lo"?
