Kollel Iyun Hadaf, Jerusalem
(a) Why is a man not Tamei if he removes Zera with a splinter of wood?2) We have learnt before that the makeup of Keri and Zivus are quite different.
(a) Considering that it is only the sighting of Zivus which breaks the seven clean days required for the Taharah of a Zav, how come that Keri breaks them, too?3)
(a) What Sha'aleh does the Gemara ask regarding the phrase "Ki Yazuv Zov Damah"?
4) The Gemara resolves the Sha'aleh of whether dry blood is Tamei, from the Mishnah 'Hamapeles ke'Min Kelifah' ... 'Tatil le'Mayim' etc.
(a) Since even dry blood is Tamei, why does she need to see whether it melts?The Gemara concludes that it is possible for a woman to miscarry in this manner. What is the miscarriage of ...
(b) red peels ...... a sign of?
5) Our Mishnah rules that if a woman miscarries a kind of fish or insect, she remains Tahor. According to Resh Lakish, Rebbi Yehudah disagrees with this, just like he disagrees with the Rabbanan with regard to a miscarried piece of flesh.
(a) What does Rebbi Yochanan say to that?We learnt earlier that, according to one Lashon, Rebbi Yochanan gives the reason of Rebbi Yehudah as being: because it is 'impossible for the womb to open without there being blood'.
(b) What will Rebbi Yochanan now say to Resh Lakish's statement?6) According to Rebbi Meir, a woman who miscarries any form of animal or bird, is Temei'ah Leida - because the Torah wrote "Yetzirah" by their creation like it wrote by the creation of Adam.
(a) What do the Rabbanan do with the Gezeirah Shavah?The Gemara tries to answer that we learn "Yetzirah" "Yetzirah" (the animals from Adam), but not "Beriyah" from "Yetzirah" (the Taninim from Adam).
(c) From which two angles does the Gemara refute this contention?The Gemara concludes that whereas "Beriy'ah" by Adam is needed to teach us his creation, "Yetzirah" is Mufneh (superfluous) for the Gezeirah Shazah, which compares the animals and the birds (where "Yetzirah" is also Mufneh, since the Torah has already written "va'Ya'as Elokim es Chayas ha'Eretz") to Adam; whereas "Beriy'ah" by the Taninim is not Mufneh.
(d) Why is the Pasuk of "Beriy'ah" not Mufneh, too, since the Torah has already written (in the Pasuk of "va'Ya'as Elokim" etc.) - "ve'es Kol Remes ha'Adamah"?7) According to the two Leshonos quoted the Gemara, everyone agrees that a Gezeirah Shavah which is Mufneh on both sides is irrefutable.
(a) What is the Machlokes between Rebbi Yishmael and the Rabbanan?
