Moed Katan 12

MOED KATAN 11, 12 - sponsored by Harav Ari Bergmann of Lawrence, N.Y., out of love for Torah and those who study it.


(a) Under which condition does Shmuel permit contracting work to a Nochri (knowing that he is likely to perform it on Shabbos)?

(b) Why does he forbid it inside the T'chum Shabbos?

(c) How do we reconcile this with Beis Hillel in Shabbos, who permit handing one's washing to a Nochri launderer on Erev Shabbos just before Shabbos comes in?

(d) In which case does ...

  1. ... Rav Papa forbid even if it is outside the T'chum?
  2. ... Rav Mesharshaya forbid even if it is outside the T'chum and there are no towns close by?
(a) Nochri contractors built Mar Zutra Brei de'Rav Nachman a mansion outside the T'chum. His colleagues (and some say even he himself) refused to enter it; according to some, because he was an important man (who should be strict with himself even where others do not need to be).
What reason do others give for their stringency?

(b) On what grounds did Rav Chama permit the joiners of the Resh Galusa to repair the tables on Chol ha'Mo'ed?

(c) May one contract a Nochri on Chol ha'Mo'ed to do something that one is not permitted to do oneself ...

  1. ... on Chol ha'Mo'ed?
  2. ... after Yom-Tov?
(d) What should one take care not to do even in the latter case?
(a) One may not breed an animal on Chol ha'Mo'ed.
What does this prohibition constitute?

(b) Which two other cases does the Tana of the Beraisa include in this prohibition?

(c) What does Rebbi Yehudah say about ...

  1. ... a she-ass in heat?
  2. ... other animals?
(a) What does the Isur of 'Ein Medairin' constitute? On which three occasions is it prohibited?

(b) What if the animals come of their own accord? May one give them any assistance, or appoint a guard, should they belong to Nochrim?

(c) If the Nochri was a 'S'chir Shabbos, S'chir Chodesh, S'chir Shanah or S'chir Shavu'a, one may assist them or appoint a guard.
What is a 'S'chir Shavu'a'? To which of the three occassions does this apply?

(d) Rebbi is lenient with regard to assisting animals that came by themselves (see Hagahos ha'Gra).
What distinction does he make regarding Shabbos, Yom-Tov and Chol ha'Mo'ed? Like whom is the Halachah?

(a) What does Rebbi Yossi say about someone whose wine was already in the pit when he became an Aveil, or something happened to prevent him from placing it in barrels before Yom-Tov or if his workers retracted?

(b) Rebbi Yehudah is more stringent.
What does he say?

(c) Having told us this with regard to ...

  1. ... oil (in the previous Mishnah), why does the Tana find it necessary to repeat it by wine?
  2. ... wine, why does the Tana find it necessary to repeat it by oil?
(a) Any Tana who requires a Shinuy by a Davar ha'Aveid on Chol ha'Mo'ed does not hold like Rebbi Yossi.
Like whom does Rav Yosef rule?

(b) What did Rav Nachman bar Yitzchak reply when they asked him whether one may cement shut a barrel of beer on Chol ha'Mo'ed?

(c) How do we know that Rebbi Yossi's concession incorporates a barrel of *beer* (as well as wine)?

(a) What did Rav Chama bar Guriah Amar Rav mean when he compared the Halachos of Chol ha'Mo'ed to the Halachos of the Kutim?

(b) Why does ...

  1. ... Shmuel permit cementing a *jar* of wine on Chol ha'Mo'ed but not a *barrel*?
  2. ... Rav Dimi from Neherda'a permit cementing a *barrel* of wine on Chol ha'Mo'ed but not a *jar*?
(c) What did Abaye mean when he compared the Halachos of Chol ha'Mo'ed to the Halachos of Shabbos? To which two Halachos in our Sugya was he referring?
Answers to questions



(a) What problem do we have with Rav Huna, who reaped on Chol ha'Mo'ed?

(b) What does the Tana Kama say about Davar ha'Aveid with regard to what is attached to the ground?

(c) Under which circumstances may one reap, pile up, thresh, winnow, select and grind?

(d) What may one nevertheless not do whilst threshing the corn?

(a) We answer the Kashya on Rav Huna (in 8a.) by establishing the author of the Beraisa to be an individual opinion (Rebbi Yossi - because, according to the Chachamim, there is no difference between what is detached and what is attached).
In that case, considering that Rebbi Yossi does not require any Shinuy by Davar ha'Aveid, why should it be necessary to avoid using cows when threshing? Is this considered a Shinuy?

(b) Grinding, chopping wood and making beer for after Yom-Tov is forbidden. If one ground corn, chopped wood or made beer for Chol ha'Mo'ed or Yom-Tov, and some was leftover, may one use it after Yom-Tov?

(c) What does the Tana of this Beraisa say with regard to deliberately grinding, chopping or making beer in excess, having in mind to use the leftovers after Yom-Tov?

(d) Another Beraisa specifically permits 'cheating' on Chol ha'Mo'ed.
What does this entail? Which Tana permits it?

(a) Shmuel was cross with Rav for reaping wheat on Chol ha'Mo'ed.
Does this mean that he holds like Rebbi Yossi, who forbids even Davar ha'Aveid by what is attached to the ground?

(b) Then why did Rav do it?

(c) What is the other reason for Shmuel being cross with Rav?

(a) Rebbi Yehudah Nesi'ah went out into the courtyard on Shabbos wearing a a metal ring with a corral stone.
What else did he do that caused Rebbi Ami to become cross with him?

(b) In either case, Rebbi Ami would not have been angry had Rebbi Yehudah Nesi'ah not been a great man.
Why not?

(a) What was Abaye's reaction to Rav Chananel Amar Rav's statement that one is permitted to cut down a palm-tree on Chol-ha'Mo'ed, even though one only needs the sawdust?

(b) Rav Ashi went on Chol ha'Mo'ed to cut down his forest in Shalnaya. What was his reply when Rav Shilo from Shalnaya reminded him that Abaye issued a curse on anyone who followed the opinion of Rav Chananel Amar Rav?

(c) What nearly happened to him? Why was that?

(d) What was his reaction to that?

(a) Rav Yehudah permitted tearing out flax, cutting down hops and uprooting sesame-seeds on Chol ha'Mo'ed.
For what might one use (on Chol'ha'Mo'ed) ...
  1. ... flax?
  2. ... hops?
  3. ... sesame-seeds?
(b) What happened the year after Rebbi Yanai picked the fruit from his orchard on Chol ha'Mo'ed?

(c) What was Rebbi Yanai's reaction to that?

(a) Under what condition is one permitted to bring in one's fruit because of thieves and one's flax from the soaking-house to save it from becoming spoiled?

(b) What happens if someone deliberately postponed either of these until Chol ha'Mo'ed?

(c) What should one be careful to do when taking one's fruit in from the field?

(d) How did Rav Yosef justify bringing beams of wood in from the field by day rather than by night?
