1)

(a)The Beraisa proves from the Pasuk "Vayikacheni be'Tzitzis Roshi" that "Tzitzis" means 'Anaf'. What does Anaf mean?

(b)Abaye rules that one must separate them ki Tzutzisa de'Arma'i. What does this mean?

(c)According to the Tana Kama in the Beraisa, if one attaches the Tzitzis to the Keren or to the G'dil, they are Kasher. What is ...

1. ... Keren?

2. ... G'dil?

(d)What does Rebbi Eliezer ben Ya'akov say?

1)

(a)The Beraisa proves from the Pasuk "Vayikacheni be'Tzitzis Roshi" that "Tzitzis" means 'Anaf' - individual threads.

(b)Abaye rules that one must separate them ki Tzutzisa de'Arma'i - like the shock of hair of a Nochri, which is stuck together next to the roots, but loose strands of hair on top.

(c)According to the Tana Kama in the Beraisa, they are Kasher if one attaches the Tzitzis to the ...

1. ... Keren - the tip of the corner of the Beged ...

2. ... G'dil - either the first few rows of material, which are reinforced to prevent the Beged from tearing easily, or the threads that protrude vertically from the warp.

(d)Rebbi Eliezer ben Ya'akov - declares both of them Pasul.

2)

(a)The Beraisa states Tzitzis Tzerichah she'Tehei Notefes al ha'Keren. What does this mean?

(b)Who is the author of this Beraisa?

(c)What is his source?

(d)According to Rebbi Ya'akov Amar Rebbi Yochanan, how far from the edge of the garment must the Tzitzis be attached?

(e)Why do we need the rulings of both Rebbi Ya'akov and Rav Papa (who gave the Shi'ur earlier as within three finger-breadths)? What would we have thought had we only been given the Shi'ur of ...

1. ... Rav Papa (but not that of Rebbi Ya'akov)?

2. ... Rebbi Ya'akov (but not that of Rav Papa)?

2)

(a)When the Beraisa states Tzitzis Tzerichah she'Tehei Notefes al ha'Keren, it means that - the Tzitzis are attached above the Keren, which they touch as they hang down.

(b)The author of the Beraisa is - Rebbi Eliezer ben Ya'akov ...

(c)=... and his source is the Pasuk - "al Kanfei Bigdeihem" (implying that they are attached to a point above the corner, and not to the corner itself).

(d)According to Rebbi Ya'akov Amar Rebbi Yochanan, the Tzitzis must be attached - at least the distance from the middle joint of the thumb to the tip of the thumbnail away from the edge of the garment.

(e)We need the rulings of both Rebbi Ya'akov and Rav Papa (who gave the Shi'ur earlier as within three finger-breadths). Because, if we had only been given the Shi'ur of ...

1. ... Rav Papa (but not that of Rebbi Ya'akov), we would have thought that - the closer the Tzitzis are to the edge of the garment, the better.

2. ... Rebbi Ya'akov (but not that of Rav Papa), we would have thought that - the further away they are from the edge, the better.

3)

(a)What did Rav Sama notice about the corner of Ravina's Tzitzis, when they were once sitting in front of Rav Ashi?

(b)What did Ravina reply when Rav Sama quoted Rebbi Ya'akov's previous ruling?

(c)What did Rav Ashi say about Ravina, to alleviate Rav Sama's embarrassment?

3)

(a)When Rav Sama and Ravina were once sitting in front of Rav Ashi, Rav Sama noticed that hole on the corner of Ravina's Tzitzis had widened until it was (or that the edge of the corner had come apart, leaving) less than the M'lo Kesher Godel required by Rebbi Ya'akov between the hole and the hem of the Beged.

(b)When Rav Sama quoted Rebbi Ya'akov's previous ruling, Ravina replied that - that is only Lechatchilah, but that provided the Tzitzis were initially Kasher, they do not become Pasul if the measurements then diminish (like Girdumei Techeiles).

(c)To alleviate Rav Sama's embarrassment, Rav Ashi declared that one person in Eretz Yisrael is worth two from Bavel (and Ravina was from Eretz Yisrael).

4)

(a)Rav Acha bar Ya'akov would fold the four Tzitzis into eight before placing them through the hole in the Beged. Why did he do that?

(b)What did he do next?

(c)And why did Rebbi Yirmiyah from Difti attach eight Tzitzis to the Beged, instead of four? What did he do next?

(d)What did Mar b'rei de'Ravina used to do?

4)

(a)Rav Acha bar Ya'akov would fold the four Tzitzis into eight before placing them through the hole in the Beged - because the Pasuk "Gedilim Ta'aseh lach al Arba Kanfos Kesuscha ... " implies that one should attach eight threads ("G'dil means four threads [two threads doubled], and Gedilim, eight [four threads doubled]) to the corner of the Beged.

(b)Then he passed the eight ends through the loop at the other end of the Tzitzis, and that is how they hung down from the Beged.

(c)Rebbi Yirmiyah from Difti attached eight Tzitzis to the Beged, instead of four - because he too explained "Gedilim" to mean eight threads, but without tying them in the way that we explained (see also Tosfos DH 'T'manya'). Then he would double them, to form sixteen threads.

(d)Mar b'rei de'Revina used to - attach four threads to the corner, and then double them, to form eight threads (like we do).

5)

(a)What B'rachah would Rav Ada bar Ahavah recite when attaching the Tzitzis to his Talis?

(b)What was Rav Nachman's reaction, when he once came across him doing that?

(c)Why did he do that?

(d)This was based on a statement of Rav. What did Rav say?

5)

(a)When attaching the Tzitzis on to his Talis, Rav Ada bar Ahavah would recite - the Berachah of La'asos Tzitzis.

(b)When Rav Nachman once came across him doing that, he reacted - by asking 'Now what's all this about Tzitzis?'

(c)He was poking fun at him ...

(d)... since Rav ruled that - attaching Tzitzis does not require a B'rachah.

6)

(a)When Rav Huna died, Rav Chisda asked how Rav could have said such a thing, in view of another ruling of his. What did Rav Yehudah Amar Rav learn from the Pasuk in Sh'lach "Daber el *B'nei Yisrael ... Ve'asu* lahem Tzitzis"?

(b)How did Rav Chisda now query Rav from there?

(c)To what principle does Rav Yosef ascribe this Kashya?

(d)We then query Rav Chida's Kashya and principle from a Beraisa, where Rebbi Meir rules that, in a town where there is no Mohel, if there is a choice between a Nochri doctor and a Kuti, it is preferable for the former to perform the Milah. Why is that?

(e)What does Rebbi Yehudah say?

6)

(a)When Rav Huna died, Rav Chisda asked how Rav could have said such a thing, in view of another ruling of Rav Yehudah Amar Rav, who learned from the Pasuk "Daber el *B'nei Yisrael ... ve'Asu* lahem Tzitzis" that - Nochrim are not eligible to attach Tzitzis.

(b)In that case, asked Rav Chisda - why did Rav rule that attaching Tzitzis does not require a B'rachah?

(c)Rav Yosef ascribes this Kashya to the principle - that any Mitzvah that can be performed by a Nochri, does not require a B'rachah; and that conversely, one that cannot, does.

(d)We then query Rav Chida's Kashya and principle from a Beraisa, where Rebbi Meir rules that, in a town where there is no Mohel, if there is a choice between a Nochri doctor and a Kuti, it is preferable for the former to perform the Milah - because if the latter performs it, he will do so in honor of Har Gerizim (where their Temple is situated).

(e)According to Rebbi Yehudah - it is the Kuti who should perform it.

7)

(a)What B'rachah does one recite over B'ris Milah?

(b)From which Tana do we now query Rav Chisda?

(c)We answer by pointing out that Rav Chisda's Kashya is aimed at Rav, who follows his own reasoning. What does Rav Papa in the name of Rav learn from the Pasuk in Lech-l'cha "va'Atah es B'risi Tishmor"?

(d)And how does Rebbi Yochanan learn it from "Himol Yimol"?

7)

(a)One recites over B'ris Milah - the B'rachah of al ha'Milah ...

(b)... posing a Kashya on Rav Chisda - from Rebbi Meir, in whose opinion a Nochri is permitted to perform it (in spite of which one recites a B'rachah).

(c)We answer by pointing out that Rav Chisda's Kashya is aimed at Rav, who follows his own reasoning. Rav Papa in the name of Rav learns from the Pasuk "va'Atah es B'risi Tishmor" that - only a Yisrael may circumcise a Jewish baby, but not a Nochri (like Rebbi Yehudah).

(d)Rebbi Yochanan learns it from "Himol Yimol" - which he Darshens as 'ha'Mal Yimol', meaning that only someone who is himself obligated to be circumcised, may circumcise others.

8)

(a)What does the Beraisa say about Succas Ovdei-Kochavim, Succas Nashim, Succas Beheimah ... '?

(b)What B'rachah does a person recite when he comes to ...

1. ... build himself a Succah (though we do not do this nowadays)?

2. ... sit in his Succah?

(c)How does this support Rav Chisda's principle?

8)

(a)The Beraisa rules that Succas Ovdei-Kochavim, Succas Nashim, Succas Beheimah ... - are all Kasher, provided they have sufficient S'chach.

(b)When a person comes to ...

1. ... build himself a Succah, he recites 'Shehechiyanu' (though we do not do this nowadays), but not 'La'asos Succah'.

2. ... sit in his Succah, he recites - 'Leishev ba'Succah'.

(c)This supports Rav Chisda's principle (according to Rav) - seeing as no B'rachah is recited over building a Succah, because Succas Nochrim is Kasher.

42b-------------------42b

9)

(a)On the other hand, we query Rav Chisda's principle from Tefilin. What does the Beraisa quoted by Rav Chin'na b'rei de'Rava from Pashranya say about a Seifer-Torah, Tefilin and Mezuzos written by ...

1. ... a Miyn, a Masur or an Akum?

2. ... an Eved, a woman or a Katan?

(b)What is the source for all this?

(c)We already cited Rav Chiya b'rei de'Rav Huna in the name of Rebbi Yochanan, regarding the B'rachah that one recites when putting on Tefilin shel Yad and Tefilin shel Rosh. What can we extrapolate from there regarding the B'rachah 'La'asos Tefilin'?

(d)What does this prove?

9)

(a)On the other hand, we query Rav Chisda's principle from Tefilin, from the Beraisa quoted by Rav Chin'na b'rei de'Rava from Pashranya, which rules that a Seifer-Torah, Tefilin and Mezuzos written by ...

1. ... a Miyn, a Masur or an Akum ...

2. ... an Eved, a woman or a Katan - is Pasul.

(b)The source for all this is - the Hekesh "Ukeshartam" "Uchesavtem", from which the Tana learns that whoever is not Chayav to put on Tefilin is not eligible to make them.

(c)We already cited Rav Chiya b'rei de'Rav Huna in the name of Rebbi Yochanan, regarding the B'rachah that one recites when putting on Tefilin shel Yad and Tefilin shel Rosh - implying that one does not recite 'La'asos Tefilin' when making them (despite the fact that a Nochri is not eligible to make them) ...

(d)... a Kashya on Rav Chisda (in the name of Rav), who considers the two interdependent.

10)

(a)How do we therefore change the criterion for which Mitzvos require a B'rachah? Why does ...

1. ... Milah require a B'rachah even though a Nochri is permitted to perform it?

2. ... neither Succah nor Tefilin require a B'rachah ('La'asos Sukah' & 'La'asos Tefilin' respectively), the latter, even though a Nochri is forbidden to perform it?

(b)What is then the basis of the Machlokes between Rav Nachman and Rav Chisda? Why does ...

1. ... Rav Chisda hold that Tzitzis requires a B'rachah?

2. ... Rav Nachman hold that it does not?

(c)Rav Mordechai cites Rav Yehudah Amar Rav differently. According to his version, what does the latter learn from the Pasuk "Daber el B'nei Yisrael ... Ve'asu lahem Tzitzis"?

(d)How does that resolve the contradiction in Rav (Rav Chisda's principle) with which we began?

10)

(a)We therefore change the criterion for which Mitzvos require a B'rachah. The reason that ...

1. ... Milah requires a B'rachah even though a Nochri is permitted to perform it is - because it constitutes the completion of the Mitzvah.

2. ... neither Succah nor Tefilin requires a B'rachah ('La'asos Succah' & 'La'asos Tefilin' respectively), the latter even though a Nochri is forbidden to perform it is - because it does not (it is only a Hechsher Mitzvah).

(b)And the reason that ...

1. ... Rav Chisda holds that Tzitzis requires a B'rachah is because he holds - Tzitzis Chovas Talis Hu (in which case it too, constitutes the completion of the Mitzvah).

2. ... Rav Nachman holds that it does not is, because he holds - Tzitzis Chovas Gavra Hu (and attaching the Tzitzis is only a Hechsher Mitzvah).

(c)Rav Mordechai cites Rav Yehudah Amar Rav differently. According to his version, the latter learns from the Pasuk "Daber el B'nei Yisrael ... Ve'asu lahem Tzitzis" that - even others (Nochrim) are permitted to make Tzitzis for a Yisrael ...

(d)... thereby resolving the contradiction in Rav with which we began - since it is now clear why (based on Rav Chisda's principle) Rav Yehudah Amar Rav exempted Tzitzis from a B'rachah.

11)

(a)Rav Yehudah Amar Rav disqualifies Tzitzis that comprise loose threads hanging from a woven fabric. He refer to them as Kotzin for one of two reasons. One is because they stand to be cut off. What iss the other?

(b)In his ruling, he incorporates Nimin (sewn threads that similarly extend from the garment) and Gardin. What are Gardin?

(c)Why are all of these Pasul?

11)

(a)Rav Yehudah Amar Rav disqualifies Tzitzis that comprise loose threads hanging from a woven fabric, which he refers to as Kotzin, either because they stand to be cut off, or - because they protrude from the Beged like thorns (Kotzin).

(b)In his ruling, he incorporates Nimin (sewn threads that similarly extend from the garment) and Gardin - fringes.

(c)All of these are Pasul - because of "Ta'aseh", 've'Lo min he'Asuy' (see also Tosfos DH 'ha'Kotzim').

12)

(a)On the other hand, Rav validates threads that are taken from Sisin (a ball of wool). What did Shmuel say when they told him of Rav's ruling? Why is that?

(b)We conclude that this a Machlokes Tana'im. What does the Tana Kama of the Beraisa say about Tefilin that one overlaid ...

1. ... with gold? Why is that?

2. ... with the skin of a Tamei animal? Why is that?

(c)He permits covering the Tefilin with the skin of a Kasher animal, however. On what grounds does Rabban Shimon ben Gamliel invalidate that too?

(d)Like whom do Rav and Shmuel (respectively) now hold?

12)

(a)On the other hand, Rav validates threads that are taken from Sisin (a ball of wool). When they told Shmuel of Rav's ruling, he retorted that - Tzitzis of Sisin are also Pasul, because Tzitzis need to be spun li'Sheman.

(b)We conclude that this a Machlokes Tana'im. The Tana Kama of the Beraisa rules that Tefilin that one overlaid ...

1. ... with gold - are Pasul, because Tefilin must be covered by the same species as the Parshiyos (animal skin).

2. ... with the skin of a Tamei animal - are Pasul, because of the Pasuk in Bo "Lema'an Tih'yeh Toras Hash-m be'Ficha" (from which we learn that holy articles may only be made of materials that are Kasher to eat.

(c)He permits covering the Tefilin with the skin of a Kasher animal, however. Rabban Shimon ben Gamliel invalidates that too - because Tefilin require Ibud (tanning) 'li'Sheman'.

(d)Shmuel (who requires Teviyah li'Sheman), now holds like Rabban Shimon ben Gamliel (who requires Ibud li'Sheman), whereas Rav holds like the Chachamim.

13)

(a)Abaye asked Rav Shmuel bar Rav Yehudah how he prepared Techeiles. He replied that he took the blood of a Chilazon and dyes. What did he do with ...

1. ... them initially?

2. ... the little bit of dye that he then poured into half an egg-shell?

(b)What do we now learn from the fact that he ...

1. ... burned the piece of dyed wool?

2. ... threw away the eggshell together with its contents?

(c)We also learn from the former that the dyeing must be done li'Shemah. What problem do we have with this statement?

(d)How does Rav Ashi resolve it?

13)

(a)When Abaye asked Rav Shmuel bar Rav Yehudah how he prepared Techeiles, he replied that he took the blood of a Chilazon and dyes. These he ...

1. ... first soaked in a caldron (see Tosfos DH 'Mishum she'Ne'emar'), a little of which ...

2. ... he poured into half an egg-shell - into which he dipped a wad of hackled wool (to test for quality).

(b)We learn from the fact that he then ...

1. ... burned the piece of dyed wool - that testing disqualifies the Techeiles from use.

2. ... threw away the eggshell together with its contents that - it also disqualifies the entire batch that was prepared for testing.

(c)We also learn from the former, that the dyeing must be done li'Shemah. The problem with this statement is - that it merely repeats the first conclusion (that testing disqualifies the Techeiles from use).

(d)Rav Ashi therefore explains that - the second conclusion is not an independent one, but is rather the explanation as to why testing invalidates the Techeiles.

14)

(a)We conclude that the previous Chidush is actually a Machlokes Tana'im. What does Rebbi Chanina ben Gamliel in a Beraisa learn from the Pasuk in Tetzaveh (in connection with the Me'il [the Kohen Gadol's cloak]) "K'lil Techeiles"?

(b)And what does Rebbi Yochanan ben Dahavai learn from the "u'Sheni Tola'as" (Ibid. [a red dye used for threads of other Bigdei Kehunah'])?

(c)What does that have to do with Techeiles?

(d)We learned in another Beraisa that Techeiles cannot be examined. Why does Techeiles require examination?

(e)What else does the Tana therefore require someone purchasing Techeiles to do?

14)

(a)We conclude that the previous Chidush is actually a Machlokes Tana'im. Rebbi Chanina ben Gamliel in a Beraisa learns from the Pasuk in Tetzaveh (in connection with the Me'il [the Kohen Gadol's cloak]) "K'lil Techeiles" that - all the Techeiles dye must go into the actual Techeiles (that it should not have been used for anything else first, and that testing will therefore disqualify it).

(b)Whereas Rebbi Yochanan ben Dahavai learns from the Pasuk in Terumah "ve'Tola'as Shani" (Ibid. [a red dye used for threads of other Bigdei Kehunah']) - that even the second red dye from the Tola'as (a worm, after it has been used for something else) is eligible for the Tola'as Shani of the Bigdei Kehunah (because testing does not disqualify it) ...

(c)... and the same will apply to Techeiles - which is mentioned in the same Pasuk.

(d)We learned in another Beraisa that Techeiles cannot be examined. Techeiles requires examination - to ensure that it is not a fake dye known as Kala Ilan.

(e)The Tana therefore requires someone purchasing Techeiles - to purchase it from an expert (who knows that Kala Ilan is forbidden [see also Tosfos DH 've'Ein Nikchin']).

15)

(a)The same Tana requires Tefilin to be purchased from an expert, even though they can easily be examined (for extra or missing letters). Why is that?

(b)In that case, why does the Beraisa conclude Sefarim u'Mezuzos ... Nikchin mi'Kol Adam?

(c)What problem do we have with the opening statement of the Beraisa Techeiles Ein lah Bedikah?

15)

(a)The same Tana requires Tefilin to be purchased from an expert, even though they can easily be examined (for extra or missing letters) - to ensure that the skin was tanned li'Shemah (like Rabban Shimon ben Gamliel, whom we cited earlier on the Amud).

(b)And the Beraisa concludes Sefarim u'Mezuzos ... Nikchin mi'Kol Adam - because Sifrei-Torah and Mezuzos do not require Ibud li'Sheman.

(c)The problem with the opening statement of the Beraisa Techeiles Ein lah Bedikah is that - we know for a fact that it can be tested, since various Chachamim did actually do so, as we will now see.
