Nidah 19


(a) What is 'Keren Karkom' (two explanations)?

(b) What is 'Meimei Tilsan'?

(c) How red is Adom, and how black is Shachor?

(d) Will a black that is darker than that or paler, be Tamei or Tahor?

(a) From which location does the earth that is used to guage the redness of 'Meimei Adamah taken'?

(b) How much water must be added to gauge this?

(c) Do the earth and the water need to be mixed together?

(d) What proportion of water must be added to the wine to produce the redness of ke'Mazug?

(a) From where do we know that there is such a thing as Dam Tahor by a woman?

(b) In light of this Derashah, what is the problem with 'Bein Nega la'Nega' - Why can we not explain it to mean 'between a Nega which is Tamei and one which is Tahor?

(c) How *do* we explain 'Bein Nega la'Nega by Nig'ei Adam, by Nig'ei Batim and by Nig'ei Begadim, and in which context is the Pasuk spraking?

(d) Why can we not learn that the Pasuk comes to distinguish between Dam Nidus and Dam Zivus, and Nig'ei Adam, Batim and Begadim?

(a) What do we learn from the Pasuk "va'Yir'u Mo'av es ha'Mayim Adumim ke'Dam"?

(b) From where do we know that there are four shades of red which are Tamei?

(c) Why then, does our Mishnah list five?

(d) Seeing as we learnt four kinds of blood from a Pasuk, how can Beis Shamai and Akavya ben Mahalalel list more? Do they not hold of the Derashah "Dameha, Dameha"?

Answers to questions



(a) What does Beis Hillel add to the Tana Kama's words, when he is Metaher 'ke'Meimei Tilsan and 'ke'Basar Tzeli'?

(b) How many opinions are there regarding blood that is Yarok (which can mean green, yellow or blue - in our Sugya, Tosfos and the Rosh contend that it is yellow)?

6) Rebbi Meir says regarding 'Im Eino Metamei Mishum Kesem, Metamei Mishum Mashkeh'. Simply explained, this appears to mean that Rebbi Meir agrees with Akavya ben Mahalalel that Dam Yarok is Metamei.
(a) How would we then explain his words, and what is his reasoning?

(b) Why does the Gemara reject this contention?

The Gemara's second contention is, that even though blood that is Yarok is not Tamei because of Nidus, why should it not be Tamei like her spittle or her urine?
(c) Why does the Gemara reject this contention?
In the Gemara's final explanation, Rebbi Meir and the Rabbanan argue over whether Dam Yarok is at least considered a liquid to be Machshir food (to be Mekabeil Tum'ah) - It is certainly not Dam Chalalim, which is the initial category of blood, which the Torah considers a liquid in this regard.
(d) What is their Machlokes?
7) Why does the Gemara quote Rebbi Yossi (regarding the previous Din), who says no more and no less, than the Tana Kama?


(a) What does Dam ha'Makeh mean according to Shmuel?

(b) Why did Shmuel not say 'ke'Dam Shechitah'?

Ula explains Dam ha'Makeh to mean 'ke'Dam Tzipor Chayah'.
c) What might Chayah mean?
9) 'Hargah Ma'acholes, Harei Zeh Toleh Bah'.
(a) What exactly does this mean according to Rebbi Chanina, and why?
Ami Vardina'ah explains that Dam ha'Makeh means that of the little finger.
(b) What other condition is necessary to gauge the redness of Dam Nidus, and whose finger are we talking about?

(c) How can we refer to a woman's husband as a Bachur who has not married?

10) The final opinion in Dam ha'Makeh is that of Rav Nachman.
(a) What does he say?
The Gemara asks on all the above opinions which restrict Dam Adom' (of our Mishnah), from the Beraisa which quotes that Rebbi Meir relied on Kiylurim, and Rebbi on the sap of a Shikmah tree, to be Metaher a woman.
(b) What does this mean, and what is the Gemara's Kashya?

(d) What is the answer?
