Moed Katan 3

MOED KATAN 3 (1 Cheshvan) - dedicated by Reb Mordechai Rabin (London/Yerushalayim) l'Iluy Nishmas his father, ha'Ga'on Rav Gedalya Rabinowitz (Manchester, England)


(a) Zemirah (pruning) is included in Zeri'ah (sowing), and Betzirah (harvesting the grapes) in Ketzirah (harvesting the corn).
Why does the Torah need to mention them?

(b) How do we reconcile this Derashah with the Beraisa, which includes many other Toldos among the prohibitions of Sh'mitah?

(c) The Tana nevertheless cites the Pasuk "*Sad'cha Lo* Sizra, ve'Charm'cha Lo Sizmor"(to learn from there that all Toldos are prohibited).
How can we even think to learn anything from such an innocuous Pasuk?

The Toldos that are forbidden in the Sh'mitah:


(a) Nichush means to weed, and Idur, to dig.
What does 'Kisu'ach' mean? How would one distinguish between Nichush and Kisu'ach?

(b) Zirud means cutting off the excess branches (both wet and dry) and Pisug supporting a tree that is sagging because it is over-moist.
What is 'Kirsum'? What is the difference between Kirsum and Zimur?

(c) 'Ein Mezavlin (manure) ve'Ein Mefarkin (remove stones from the roots of the tree)'.
What is the meaning of ...

  1. ... 'Ein Me'avkin?
  2. ... 'Ein me'Ashnin'?
(a) On what grounds does the Tana permit digging (Kishkush) under the olive-trees and (Idur) under the vines, filling the pits with water and building mounds of earth around the vines (Ugi'os)?

(b) But how can the Tana permit Kishkush in the Sh'mitah, when another Beraisa specifically prohibits it?

(a) Rebbi Yochanan and Rebbi Elazar argue over whether one receives Malkos for plowing in the Sh'mitah or not. We initially connect their Machlokes to a statement made by Rebbi Avin Amar Rebbi Ila'a (with regard to a 'K'lal u'F'rat'.
Which statement?

(b) We conclude however, that both disputants disagree with Rebbi Avin.
In that case, why should one *not* receive Malkos for plowing?

(c) From where does the Tana learn that digging under the olive-trees and under the vines, filling the pits with water and building mounds of earth around the vines is permitted?

Answers to questions



(a) We did not at first know what Rav Dimi meant when he came from Eretz Yisrael and said that although one might have thought that one receives Malkos for performing Tosefes of Sh'mitah, we have a Pasuk to teach us that he does not. Rebbi Elazar connects Rav Dimi's statement with the Halachah that we just learned.
What does Tosefes then mean?

(b) Which 'Pasuk' teaches us that he is Patur?

(c) Rebbi Yochanan interprets 'Tosefes' literally.
To which prohibition would Rav Dimi then have been referring?

(d) And from which Pasuk did he learn it?

(a) According to Beis Shamai, one is permitted to plow a field of trees in the year of Erev Sh'mitah, as long as it benefits the sixth-year fruit.
What does Beis Hillel say? How wide is the gap between the two opinions?

(b) The Tana Kama of the Mishnah in Shevi'is permits plowing a wheat-field on Erev Shevi'is as long as some moist remains from last year's rains.
Why is that?

(c) On what grounds does Rebbi Shimon object to this?

(d) What time limit does he therefore give for plowing ...

  1. ... a wheat-field?
  2. ... a field of trees?
(a) Rebbi Yehoshua ben Levi maintains that Raban Gamliel and his Beis-Din nullified the ruling of Beis-Shamai or Beis Hillel and permitted plowing up to Rosh Hashanah.
What problem do we have with this radical statement?

(b) And what problem do we have with Rebbi Avahu (or Rebbi Yochanan)'s reply (that Beis Shamai and Beis Hillel stipulated when they issued the decree that a later Beis-Din would be able to rescind it)?

(c) How do resolve this problem? What exactly was forbidden Halachah le'Moshe mi'Sinai and what was decreed by Beis Shamai and Beis Hillel?

(a) According to Rebbi Akiva, the Pasuk in Ki Sisa "be'Charish u've'Katzir Tishbos" refers to the Dinim of Sh'mitah.
What does it come to teach us?

(b) How does Rebbi Yishmael explain the Pasuk (with regard to Shabbos)?

(c) Rav Nachman bar Yitzchak suggests that the *Halachah* comes to permit young trees, and the *Pasuk*, to forbid old ones.
What does he mean by ...

  1. ... 'permitting young trees'? How many trees are we talking about, and until when may one plow?
  2. ... 'permitting old trees'?
(d) But this is senseless! Surely, once we have the Halachah permitting young trees, we know automatically that old trees are forbidden (even without a Pasuk). So how does Rav Nachman bar Yitzchak really differentiate between the Halachah and the Pasuk (of "be'Charish u've'Katzir Tishbos")? Who learns the Halachah, and who, the Pasuk?
