What if the Zav's spit does not actually touch the person but lands on the stick that he is holding?
Rashi: Spit is Metamei the person who touches it and who carries it 1 - together with the clothes he is wearing.
Even if it landed on the stick that he is holding (Sifsei Chachamim) - provided he walks with it or moves it.
What is the Din regarding other fluids that a Zav emits?
Rashi (in Shabbos, 14b): All fluids of a Zav that gather before being emitted - such as his urine 1 and his mucus, 2 are Metamei like his spit. 3
Nidah 55b ?ve?Chi Yarok ha?Zav? incorporates phlegm, mucus and mucus from the nose.
Refer also to 15:3:0.1:1.
Except for his blood. Refer to 15:3:0.3:2.
Because they are all included in "ve'Chi Yarok". See Torah Temimah, note 36. And the Torah uses the word "Yarok" .
"ve'Chi Yarok ha?Zav ba'Tahor". What are the implications of "ve'Chi Yarok??
Sifra: Refer to 15:8:2:2.
Nidah 57a: to teach us that they are only Metamei whilst they are moist ? like spit.
"ve'Chi Yarok ha?Zav ba'Tahor". Why does the Torah insert the (otherwise superfluous) word ?ba?Tahor??'
Rashi: To teach us that the person is only Tamei if the spit actually touches his body 1 as opposed to the spit of a Yevamah. 2
Nidah 55b: It teaches us that the liquids of a Zav are Metamei be?Masa ? even if they are not touching the body of the Zav. 3
Why are the fluids of a Zav Tamei after they separate from him?
Moshav Zekenim citing R. Yehudah ha'Chasid: There is life in a person's limbs, even after they separate from him. Limbs are different than fluids. 1
I do not understand this. If limbs and fluids are the same, there is reason to consider the fluid Tamei, for it is as if it is part of him even after it separated! (PF)
