(a)We have already discussed the Machlokes between Rebbi Yehudah ben Beseira and the Rabbanan (with regard to 'Nishba Levateil or Lekayem es ha'Mitzvah'). If Rebbi Yehudah ben Beseira validates such a Shevu'ah 'Kal va'Chomer' from a Shevu'as ha'Reshus, on what grounds do the Rabbanan consider it invalid?

(b)How do they learn 'Lekayem' from there?

(c)From which Pasuk does the Beraisa learn this Halachah?

(d)And from where does the same Tana learn that ...

1. ... 'Nishba Levatel es ha'Mitzvah ve'Lo Bitel Patur'?

2. ... 'Nishba Lehara Le'atzmo ve'Lo Heira, Chayav'?

(e)And from where does the Tana ...

1. ... preclude 'Nishba Lehara la'Acherim'?

2. ... include 'Nishba Leheitiv la'Acherim'?

1)

(a)We have already discussed the Machlokes between Rebbi Yehudah ben Beseira and the Rabbanan (with regard to 'Nishba Levateil or Lekayem es ha'Mitzvah'). Rebbi Yehudah ben Beseira validates such a Shevu'ah 'Kal va'Chomer' from a Shevu'as ha'Reshus, whereas the Rabbanan consider it invalid - because, unlike Shevu'as ha'Reshus, it is not subject to 'La'av ke'Hein', as we learned above.

(b)They learn 'Lekayem' from there - since contravening an Asei is not R'shus.

(c)The Beraisa learns this Halachah - from "Lehara O Leheitiv", 'Mah Hara'ah R'shus, Af Hatavah R'shus'.

(d)The Tana learns that ...

1. ... 'Nishba Levatel es ha'Mitzvah ve'Lo Bitel Patur' - from the same Pasuk (but in the reverse order [as will be explained shortly]) 'Mah Hatavah R'shus, Af Hara'ah R'shus'.

2. ... 'Nishba Lehara Le'atzmo ve'Lo Heira, Chayav' - from the same source again 'Mah Hatavah R'shus ... '.

(e)The Tana ...

1. ... precludes 'Nishba Lehara la'Acherim' - from 'Mah Hatavah R'shus ... ' (and one has no permission to harm another Jew).

2. ... includes 'Nishba Leheitiv la'Acherim' - from the word "O".

2)

(a)The problem with establishing "Lehara O Leheitiv by a D'var Mitzvah is based on the fact that we either compare Hara'ah to Hatavah or Hatavah to Hara'ah. Assuming the former, the Tana learns that Hatavah does not entail a Bitul Mitzvah. What does he mean by that?

(b)On what basis does he take this for granted?

(c)If we now compare Hara'ah to Hatavah, how will we establish Hara'ah?

(d)What is the problem with that?

2)

(a)The problem with establishing "Lehara O Leheitiv by a D'var Mitzvah is based on the fact that we either compare Hara'ah to Hatavah or Hatavah to Hara'ah. Assuming the former, the Tana learns that Hatavah cannot entail a Bitul Mitzvah - such as eating on Yom Kipur or eating Chametz on Pesach, but only a Kiyum Mitzvah, such as eating Matzah on Seider-night.

(b)And he takes this for granted - because if the Nishba then carried out his Shevu'ah, it will be considered Hara'ah (to his soul) and not Hatavah.

(c)If we now compare Hara'ah to Hatavah, we will likewise establish Hara'ah - not by a Bitul Mitzvah, such as not to eat Matzah on Seder-night, but by a Kiyum Mitzvah, such as not to eat Chametz on Pesach.

(d)The problem with that is that - since we already know Kiyum Mitzvah by Shevu'ah from Hatavah, why does the Torah need to repeat the same Halachah in the form of Hara'ah?

3)

(a)Assuming on the other hand, that we compare Hatavah to Hara'ah, then we will learn that just as Hara'ah does not speak by a Kiyum Mitzvah (such as not eating Chametz on Pesach), neither will Hatavah speak by a Kiyum Mitzvah (such as eating Matzah on Seder night), only by a Bitul Mitzvah (to eat Chametz on Pesach). Why do we take for granted that the Tana is not speaking about a Kiyum Mitzvah?

(b)What are trying to prove from the above Kashyos?

(c)If "Lehara" and "Leheitiv" are referring to a D'var ha'Reshus, how will we then compare ..

1. ... Hara'ah to Hatavah?

2. ... Hatavah to Hara'ah?

(d)How will the Kashyos that we asked previously apply here too?

3)

(a)On the other hand, assuming that we compare Hatavah to Hara'ah, then we will learn that just as Hara'ah cannot speak by a Kiyum Mitzvah (such as not eating Chametz on Pesach), neither will Hatavah speak by a Kiyum Mitzvah (such as eating Matzah on Seder night), only by a Bitul Mitzvah (to eat Chametz on Pesach). We take for granted that the Tana is not speaking about a Kiyum Mitzvah - because that would then be Hatavah and not Hara'ah.

(b)From the above Kashyos, we are trying to prove that - Hara'ah and Hatavah must be speaking about a D'var ha'Reshus.

(c)If "Lehara" and "Leheitiv" are referring to a D'var ha'Reshus, we will then compare ..

1. ... Hara'ah to Hatavah - in that just as Hatavah refers to something that causes no bodily harm to the Nishba (otherwise it will be Hara'ah), and that is beneficial, then likewise Hara'ah will refer to something that is good for him, such as not to eat something that is harmful.

2. ... Hatavah to Hara'ah - in that just as Hara'ah refers to desist from eating, not something that is harmful (as that would be called Hatavah), but something that is good for the body, so too, does Hatavah refers to a Shevu'ah to eat something that is not beneficial to the body, but that is harmful.

(d)The Kashyos that we asked previously will apply here too however - because in the first case Hara'ah is superfluous (since it is really Hatavah), and so is Hatavah in the second case (since it is really Hara'ah).

4)

(a)How do we finally learn R'shus from the fact that the Torah found it necessary to write "O" to teach us Hatavas Acherim?

(b)What problem do we have with this? What else might we Darshen from "O"?

(c)This is only a problem according to Rebbi Yashiyah, who Darshens from the Pasuk in Kedoshim "Ish Asher Yekalel es Aviv ve'es Imo ... Aviv ve'Imo Kilel" 'Aviv Kilel, Imo Kilel'. How does he extrapolate this from the Pasuk?

(d)What do we learn from there regarding 'O', which poses a Kashya on our Sugya?

4)

(a)We finally learn R'shus from the fact that the Torah found it necessary to write "O" to teach us Hatavas Acherim - because if 'Hatavah' and 'Hara'ah' were referring to Kiyum and Bitul Mitzvah respectively (and Bitul Mitzvah would apply to Acherim just like it applies to oneself), then, now that Hara'as Acherim is included, Kal va'Chomer Hatavas Acherim.

(b)The problem with this is - that "O" is needed to teach us that Shevu'as Bituy applies to either Hara'ah or Hatavah, and that it does not require both.

(c)This is only a problem according to Rebbi Yashiyah, who Darshens from the Pasuk in Kedoshim "Ish asher Yekalel es Aviv ve'es Imo ... Aviv ve'Imo Kilel" 'Aviv Kilel, Imo Kilel', which he extrapolates from the fact that, at the beginning of the Pasuk, the Torah places 'K'lalah' next to "Aviv", and at the end of the Pasuk, next to "Imo".

(d)We learn from there - that, according to Rebbi Yashiyah, when the Torah writes a 'Vav' and not "O", it means 'and' and not 'either or' (otherwise, he would not need "Aviv ve'Imo Kilel" to separate them).

5)

(a)There is no problem according to Rebbi Yonasan. What does Rebbi Yonasan say regarding the Pasuk in Kedoshim? What would the Torah have had to insert had it meant Aviv and Imo?

(b)We resolve the problem by establishing Rebbi Yashiyah like Rebbi Akiva (whom we discussed earlier in the Perek). What does Rebbi Akiva say?

(c)What does he now learn from the Miy'ut "Lehara O Leheitiv"?

(d)And what is his source for precluding also Nishba Lekayem es ha'Mitzvah?

5)

(a)There is no problem according to Rebbi Yonasan however, who explains that - as long as the Torah does not insert the word 'Yachdav', the 'Vav' can also mean 'or'.

(b)We resolve the problem by establishing Rebbi Yashiyah like Rebbi Akiva (whom we discussed earlier in the Perek) - who Darshens 'Ribuyi, Mi'uti ve'Ribu'i'.

(c)He now learns from the Miy'ut "Lehara O Leheitiv" - to preclude 'Nishba Levatel es ha'Mitzvah' (which is the most obvious thing to preclude).

(d)And his source for precluding also Nishba Lekayem es ha'Mitzvah is - the fact that it is not subject to 'La'av va'Hein'.

27b----------------------------------------27b

6)

(a)How did Rebbi Yehudah ben Beseira counter the Rabbanan's argument (that Kiyum Mitzvah is not 'be'La'av ve'Hein')?

(b)And what do the Rabbanan say to that?

6)

(a)Rebbi Yehudah ben Beseira will counter the Rabbanan's argument (that Kiyum Mitzvah is not 'be'La'av ve'Hein') - by comparing this case to that of 'Hatavas Acherim', which the Beraisa (in the previous Sugya) included, despite the fact that 'Hara'as Acherim' is not permitted.

(b)To which the Rabbanan will reply that - even though Hara'as Acherim is forbidden, the case of "Lehara" is nevertheless applicable where the Nishba says 'Lo Eitiv'.

7)

(a)What does our Mishnah say about a case where someone declares 'Shevu'ah she'Lo Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah, Shevu'ah she'Lo Ochlenah, ve'Achlah'? How many Korbanos will he have to bring if he transgresses be'Shogeg?

(b)This is a typical case of Shevu'as Bituy. What is the punishment for transgressing either a Shevu'as Bituy or a Shevu'as Shav, be'Meizid?

(c)What happens to someone who contravenes a Shevu'as Shav be'Shogeg?

7)

(a)In a case where someone declares 'Shevu'ah she'Lo Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah, Shevu'ah she'Lo Ochlenah, ve'Achlah', our Mishnah rules - 'Eino Chayav Ela Achas' (one Korban, if he transgressed be'Shogeg).

(b)This is a typical case of Shevu'as Bituy. If someone transgresses either a Shevu'as Bituy or a Shevu'as Shav be'Meizid - he is Chayav Malkos.

(c)Someone who contravenes a Shevu'as Shav be'Shogeg - is not subject to any official punishment.

8)

(a)What problem do we have with the Tana's Lashon 'Shevu'ah she'Lo Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah ... '?

(b)What do we first of all extrapolate from the change of expression?

(c)The reasoning behind this distinction is based on a statement of Rava. How does Rava differentiate 'Lo Ochal Kikar Zu' and 'she'Lo Ochlenah'?

(d)How will this now explain the Mishnah's distinction? Why, if he says 'Shevu'ah she'Lo ...

1. ... Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah ... ' is he Chayav only one set of Malkos?

2. ... 'Ochlenah Kikar Zu, Lo Achal' will he be Chayav two sets of Malkos?

8)

(a)The problem with the Tana's Lashon 'Shevu'ah she'Lo Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah ... ' is - why he changed from 'she'Lo Ochal' to 'she'Lo Ochlenah'.

(b)First of all we extrapolate from the Mishnah that - had he inverted the order ('Lo Ochlenah Kikar Zu, Lo Achal'), he would have been Chayav two Chata'os.

(c)The reasoning behind this distinction is based on a statement of Rava, who rules that - 'Lo Ochal Kikar Zu' implies a k'Zayis, whereas 'she'Lo Ochlenah' implies the entire loaf.

(d)Consequently, if he says 'Shevu'ah she'Lo ...

1. ... Ochal Kikar Zu, Shevu'ah she'Lo Ochlenah ... ' he is Chayav only one set of Malkos - because 'she'Lo Ochlenah' is included in she'Lo Ochal' (since if each k'Zayis is already forbidden, how much more so the entire loaf), and the principle 'Ein Shevu'ah Chalah al Shevu'ah' will prevent the second Shevu'ah from taking effect.

2. ... 'Ochlenah Kikar Zu, Lo Achal' he will be Chayav two sets of Malkos - since 'she'Lo Ochal' adds a Chiyuv for each k'Zayis.

9)

(a)Regarding our Mishnah, we already know that 'Ein Shevu'ah Chalah al Shevu'ah' from the first 'Shevu'ah she'Lo Ochlenah'. So why does the Tana find it necessary to add a second 'Shevu'ah she'Lo Ochlenah'?

(b)The ramifications of this statement are based on a ruling of Rava. What did Rava say about someone who made one Shevu'ah after the other, and subsequently had the first Shevu'ah revoked?

(c)In similar vein, what does the Beraisa say about someone who declares two sets of Nezirus, and who, at the end of thirty days, has already designated his Korban, when he decides to have his first Nezirus revoked?

(d)Why does this Beraisa not support Rava? What makes the case of two Nezirus different than two Shevu'os?

9)

(a)Regarding our Mishnah, we already know that 'Ein Shevu'ah Chalah al Shevu'ah' from the first 'Shevu'ah she'Lo Ochlenah'. Nevertheless, the Tana finds it necessary to add a second 'Shevu'ah she'Lo Ochlenah' to teach us that - even though the Nishba is not Chayav, the Shevu'ah is effective.

(b)The ramifications of this statement are based on a ruling of Rava, who said that if someone made one Shevu'ah after the other, and subsequently had the first Shevu'ah revoked - the second one (which was hanging in abeyance) then comes into effect.

(c)In similar vein, the Beraisa rules that, in a case where someone declares two sets of Nezirus, and who, at the end of thirty days, has already designated his Korban, when he decides to have his first Nezirus revoked - the Nezirus that he observed counts as his second Nezirus, and he may bring the animal that he designated as its Korban.

(d)This Beraisa does not support Rava however - because whereas there, the second Nezirus would have taken effect (after the termination of the first) even if the first one had not been revoked, in our case, the second Shevu'ah would not have taken effect at all, had he not revoked the first.

10)

(a)What does Rava say about someone who forbade on himself a loaf of bread with a Shevu'ah, and after eating part of it, he wants to have the Shevu'ah revoked? Under what condition is he permitted to do so?

(b)What problem does Rav Acha b'rei de'Rava have with this, assuming that he originally declared ...

1. ... 'she'Lo Ochal Kikar Zu'?

2. ... 'she'Lo Ochlenah'?

(c)Rav Ashi establishes Rava's ruling either way. How does he establish it, assuming the Nishba said ...

1. ... 'she'Lo Ochal Kikar Zu'?

2. ... 'she'Lo Ochlenah'?

10)

(a)If someone forbids a loaf of bread on himself with a Shevu'ah, and after eating part of it, he wants to have the Shevu'ah revoked, Rava rules that he is permitted to do so - provided at least one k'Zayis of it remains.

(b)The problem Rava's son Rav Acha has with this, assuming that he originally declared ...

1. ... 'she'Lo Ochal Kikar Zu' is - why did he not irrevocably transgress with each k'Zayis that he ate?

2. ... 'she'Lo Ochlenah' is that - even if a Kol Shehu remains, there seems to be no reason why it cannot be revoked.

(c)Rav Ashi establishes Rava's ruling either way. Assuming the Nishba said ...

1. ... 'she'Lo Ochal Kikar Zu', he explains - since ('Migu') the nullification of the last k'Zayis is effective, it also incorporates the rest of the loaf.

2. ... 'she'Lo Ochlenah', he says that - less than a k'Zayis is not sufficiently Chashuv to become revoked.
