Nedarim 21


(a) What does the Yerushalmi mean when it says about Nidrei Ziruzin 'Aval be'Mama'amidin, Tzerichin Heter Chacham'?

(b) Why is this not obvious from the Seifa of the Mishnah 'Sh'neihen Rotzin bi'Sheloshah Dinrim'? How might we have otherwise explained that?

(c) And what does the Yerushalmi say about someone who, in the process of selling an article to one of two prospective buyers, makes a Neder which he intends to be a Neder Ziruzin as regards one, but literally, as regards the other?

(a) In the case of our Mishnah, the seller is permitted to accept less than three Dinrim and the buyer more.
Why is that?

(b) Is the seller permitted to accept a Shekel or the buyer to pay a Sela?

(c) Does "Lo Yachel Devaro" apply at all, to the four cases in our Mishnah?

(a) On what basis did Rebbi Ami establish the four Nedarim like Rebbi Yehudah Amar Rebbi Tarfon? What did Rebbi Yehudah Amar Rebbi Tarfon say (regarding Nezirus)?

(b) How does Rava refute Rebbi Ami's explanation, based on the Lashon 'Sh'neihen Rotzin' (in the present tense)?

(c) According to Rebbi Ami, why does the Tana need to add the clause that they both agreed on the compromise of three Shekalim? What difference does it make how much the buyer eventually paid, seeing as the Neder was already Bateil?

(a) Ravina asked Rav Ashi whether it will be considered Nidrei Ziruzin even if the seller stated a price over and above a Sela (a "Sela plus a P'rutah), and the buyer a price less than a Shekel (a Shekel minus a P'rutah). This might not be included in Nidrei Ziruzin because they entered into such detail.
What other reason might there be for precluding it from Nidrei Ziruzin?

(b) What does the Tana of the Mishnah in Konem Yayin say about someone who countered his friend's efforts to invite him for a meal, with a Neder 'Konem Beischa she'Ani Nichnas, Tipas Tzonan she'Ani To'eim'?

(c) How does Rav Ashi try to resolve Ravina's She'eilah from there?

(d) How do ...

  1. ... we refute Rav Ashi's proof from there?
  2. ... we rule in this issue, seeing as the She'eilah ends with 'Teiku'?
Answers to questions



(a) What did Shmuel retort when Rav Yehudah quoted to him Rav Asi, who said that the four cases of Nidrei Ziruzin all require nullification?

(b) In the second Lashon, Rav Yosef quotes Rav Yehudah Amar Rav Asi as saying that a Chacham is only permitted to annul Nedarim that resemble the four on our Mishnah.
What did he mean by that?

(c) What did Rav Huna mean when he asked the man who came to nullify his Neder 'Libech Alach'?

(d) How do we know that Charatah that is not retroactive is not considered Charatah?

(a) Rabah bar Rav Huna disagrees with his father (and the same Machlokes appears in a Beraisa). He annulled the Neder of a man on the basis of the fact that, had there been ten men to appease him, he would not have made the Neder in the first place.
Why does it make no difference whether we conclude 'Poschin Charatah', or 'Ein Poschin ba'Charatah'? Under what category does this case fall?

(b) When Rebbi Asi asked that man who came to him to annul his Neder 'Kadu Tih'yeh', he replied 'Lo', on the basis of which he annulled it.
What did ...

  1. ... Rebbi Asi mean when he said 'Kadu Tih'yeh'?
  2. ... the man mean when he replied 'Lo'?
(c) How do we reconcile Rebbi Asi here, who holds 'Poschin ba'Charatah', with Rav Asi earlier, who, Rav Yehudah maintained, holds 'Ein Poschin ba'Charatah'?
(a) What did Rebbi Elazar mean when he asked the man who came to have his Neder annulled 'Ba'is Nadur'?

(b) What did the man reply, and what did Rebbi Elazar rule?

(c) On what grounds did Rebbi Yochanan annul the Neder of that woman who forbade her daughter by means of a Neder to derive benefit from her?
