Moed Katan 19

MOED KATAN 19, 20 - anonymously dedicated my an Ohev Torah and Marbitz Torah in Ramat Beit Shemesh, Israel.


(a) One is ordinarily not allowed to write Sh'tarei Chov on Chol ha'Mo'ed. It is however, permitted in two cases; one of them, if the creditor does not trust the debtor. What is the other?

(b) The Tana Kama forbids writing Sefarim, Tefilin and Mezuzos on Chol ha'Mo'ed.
Does this prohibition extend to correcting Seifer Ezra? What else might Seifer Ezra mean?

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

  1. ... writing Sefarim, Tefilin and Mezuzos on Chol ha'Mo'ed?
  2. ... spinning T'cheiles?
(a) Rebbi Meir in the Beraisa holds like Rebbi Yehudah in our Mishnah (who permits writing Sefarim, Tefilin and Mezuzos for oneself on Chol ha'Mo'ed). What does he say about writing them for others?

(b) Rebbi Yehudah in the Beraisa is more strict.
What does he say?

(c) Rebbi Yossi is the most lenient of all.
What does *he* say?

(d) What ruling did Rav or Rabah bar bar Chanah issue to Rav Chananel?

(a) Rebbi Eliezer permits spinning on one's lap but not using a stone. What does using a stone mean?

(b) The Rabbanan permit even using a stone. Rebbi Yehudah quotes Rebbi Eliezer slightly more leniently than the Tana Kama quotes him.
What does *he* say?

(c) What do the Chachamim then say?

(d) How do both Shmuel and Rebbi Yochanan both rule?

(a) According to our Mishnah, how long before Yom-Tov must one have buried one's dead for Yom-Tov to negate ...
  1. ... the Shiv'ah?
  2. ... the Sh'loshim?
(b) Which three Dinim does the latter incorporate?

(c) With regard to the Dinim of mourning, in which way is ...

  1. ... Yom-Tov more lenient than Shabbos?
  2. ... Shabbos more lenient than Yom-Tov?
(a) What does Rebbi Eliezer say about Shavu'os after the Churban Beis Hamikdash, when it no longer has seven days of Tashlumin?

(b) What does Raban Gamliel say about Rosh Hashanah and Yom Kipur?

(c) What compromise do the Chachamim make between Rebbi Eliezer and Raban Gamliel?

(d) What do Rav and Rav Huna mean when they say 'Gezeiras Batlu, Yamim Lo Batlu'?

Answers to questions



(a) Rav Sheishes holds 'Afilu Yamim Nami Batlu'.
What does he mean?

(b) What do we prove from the Beraisa, where the Tana Kama appears to support Rav and Huna and Aba Shaul that of Rav Sheishes (see also Tosfos DH 've'ha'Tanya')?

(c) Why does Aba Shaul say that the Mitzvah of *seven* days negates the Sh'loshim, when our Mishnah requires *eight*?

(d) What is the meaning of 've'Yom ha'Shevi'i Oleh Lo le'Kahn u'le'Kahn'?

(a) Is the Halachah like the Chachamim or like Aba Shaul?

(b) In which case do the Chachamim agree with Aba Shaul that the Aveil may shave on the seventh day?

(c) What important leniency regarding the seventh day of every Aveilus emerges from Aba Shaul's ruling?

(a) Abaye rules like Aba Shaul (that 'Miktzas ha'Yom ke'Kulo') with regard to the seventh day, and, he maintains, the Chachamim agree with him with regard to the thirtieth (that 'Miktzas ha'Yom ke'Kulo'). What does Rava say?

(b) On what do the Neherda'i, who disagree with both Abaye and Rava, rule like Aba Shaul both as regards thirty days and as regards seven, base their ruling?

(a) What do we learn from ...
  1. ... the 'Gezeirah-Shavah' "Rosheichem Al *Tifra'u*" (Shemini) from Nazir "Gadeil Pera Se'ar Rosho" (Naso)?
  2. ... the Pasuk in Naso "Kadosh Yihyeh"?
(b) According to Rav Huna Brei de'Rav Yehoshua, even Aba Shaul does not always hold 'Miktzas ha'Yom ke'Kulo'.
In which case does he in fact agree that the Aveil has to wait for nightfall before he may wash?

(c) What do Rav Papa and Rav Papi say about this?

(a) Abaye asked Rabah whether, if they buried a Meis on Yom-Tov, Yom-Tov will negate the Sh'loshim or not.
Why did he not ask him the same She'eilah regarding the Shiv'ah?

(b) What did Rabah answer him?

(a) The Beraisa maintains that, if someone buries his deceased relative two days before Yom-Tov, 'Nichum Aveilim' does not apply after Yom-Tov, because people already performed it during Yom-Tov.
Then in which regard does the Tana say that he counts another five days after Yom-Tov?

(b) If he buried him three days before the end of Yom-Tov, the same distinction applies.
What is the Din regarding 'Nichum Aveilim'?

(c) The Beraisa ends with 've'Regel Oleh Lo', referring to the Din of Sh'loshim.
Why do we at first think that this is a Kashya on Rabah?

(d) How do we refute the Kashya?
