(a) Is the first sighting of a Zav Metamei be'Masa?2)
(a) How does the Gemara attempt to resolve the Sha'aleh from the Beraisa, which derives from "Zovo Tamei Hu", that Zivus is Metame be'Masa?Abaye queries Rav Yosef, who posed the Sha'aleh in the first place. But didn't Rav Yosef himself learn from "Zos Toras ha'Zav" that even a Katan is Metamei be'Zov, leaving "la'Zachar ve'La'Nekeivah" open to learn the Ma'ayanos of a Metzora and a Metzora'as?
(c) How does Abaye resolve Rav Yosef's Sha'aleh from here?3)
(a) What is the difference between the first sighting of a Zav and the second, with regard to seeing be'Ones, and what is the source for the Din by the first sighting?4) 'Rebbi Eliezer Omer: Af bi'Shelishi, Bodkin Oso Mipnei ha'Korban'.
(a) What is the Machlokes Rebbi Eliezer and the Rabbanan?According to Rebbi Eliezer, it is only by the fourth sighting that a Zav has the Din of a Zavah regarding Metamei be'Ones.
(b) What are the ramifications of this statement - Why can it not be a question of Tuma'h or Korban?The Beraisa writes, that in one way a Zav is more lenient than a Ba'al Keri, and in another way he is stricter.
(c) What does this mean, and why can the Beraisa not be referring to the first sighting?
5) How does Zivus differ from Keri?
(a) According to Beis Shamai, why is a Yoledes who did not Tovel, different than a Nidah?Beis Hillel retort that a Yoledes be'Zov, who is Temei'ah after fourteen days if she did *not* Tovel, even though she is Tehorah if she *did*, should serve as a precedent.
(b) How do Beis Shamai respond to that?7) According to Rav, the Ma'ayan of the days of Tum'ah and that of Tahor are one and the same, only the Torah declares the blood of the first period Tamei, and that of the second period, Tahor.
(a) What does Levi hold, and what are the differences between them?8)
(a) If, as Levi learns, the Beraisa speaks when the blood did not stop flowing from the days of Tum'ah to the days of Taharah, what is the reason of Beis Shamai, who rules that she is Tehorah?According to Levi, Beis Shamai holds like Rav, whilst *he* follows the opinion of Beis Hillel.
(b) But how does Rav explain Beis Hillel?9) The Beraisa writes "Devosah" - le'Rabos es Bo'alah; "Titma" - le'Rabos ha'Leilos; "Devosah Titma" - le'Rabos ha'Yoledes be'Zov, she'Tzerichah she'Teishev Shiv'ah Yamim Neki'im.
(a) What do these three things mean?
