Previous daf

Nidah 17

1) Rebbi Shimon bar Yochai states that Hashem hates anyone who is intimate in front of any living creature.

(a) Does that mean that one is obligated to chase away the mice from under the bed?

(b) Why were certain people intimate in the presence of their slaves - in spite of the above statement?

(c) What Chumra did some of the Amora'im adopt in this regard?

2)
(a) Under which circumstances is it dangerous to eat peeled garlic, onions or eggs, and when is it safe to do so?

(b) What should one avoid drinking under similar circumstances, and what added condition would be required before it becomes dangerous?

3) It is also dangerous to sleep in a cemetery.
(a) What does one want to achieve by doing this, and why is it dangerous?

(b) Why is it wrong to throw one's cut nails into the street? Is there any difference whether one cuts them off with scissors or using any other means, whether one cuts off the finger-nails as well, or only the toenails? And is there any difference whether he cuts something else afterwards or not?

(c) What should one do with one's cut nails?

(d) What happens to someone who is Meshamesh after bloodletting, and when does it not apply?

4)
(a) For which two reasons should one not be Meshamesh by day, and under which circumstances is it permitted?

(b) How do we then explain the Beraisa where Beis Shamai say 'O Teshamesh le'Or ha'Ner'?

(c) Then how do we explain the Beraisa which says 'Af al Pi she'Amru ha'Meshamesh le'Or ha'Ner, Harei Zeh Meguneh'...?

(d) Why should it be Meguneh to examine the Eid by the light of a lamp?

5) The Gemara concludes that Moonbaz' household used to examine the Eidim by the light of day.
(a) Why might it nevertheless have been praiseworthy, even according to the original text - that they used to make Tashmish by the light of day?

(b) What did the Bnei Eretz Yisrael mean when they used to announce every Friday 'Ma'an Ba'ei Pekuli be'Nahama?'

(c) When is linen good to use as an Eid, and when is it not?

(d) What other material is a good agent for Bedikah?

6) Initially, snow is considered to be neither a food nor a drink, so it is not Mekabeil Tum'ah.
(a) What will be the Din if one thinks to eat it or drink it?
Normally, if one snowflake in a batch of snowflakes becomes Tamei, the others do not.
(b) What is the exception to this rule, and why?

17b---------------------------------------17b

7)

(a) What are the Cheder, the Perozdor and the Aliyah, and what is the Din of blood found there according to the Mishnah?

(b) What is the Lul, and how do Rami bar Shmuel and Rav Yitzchak brei d'Rav Yehudah differentiate between the blood found in the front of the Lul and blood found in the back - how will that now affect the Peshat in our Mishnah?

(c) Why did Raba bar Rav Huna object to that interpretation and how did Rav Huna himself (the Rosh Yeshivah) present his opinion?

Abaye maintains that either both blood at the back of the Lul and at the front are Safek, or the blood at the back is Vaday Tamei and blood at the front is Vaday Tahor.
(d) Why?
8)
(a) Does one bring a Korban - according to any opinion - for having intimacy with a woman who found blood in the front part of the Lul?

(b) Rami bar Shmuel and Rav Yitzchak brei d'Rav Yehudah, who maintain that blood at the back of the Lul is Safek Tamei, certainly conform with the opinion of Rav Ketina. But can one reconcile their opinion with that of Rebbi Chiya, who holds that blood at the back of the Lul is Vaday Tamei?
