Previous daf Moed Katan 6
MOED KATAN 6 - dedicated by Mr. Avi Berger of Queens, N.Y. in memory of his
parents, Pinchas ben Reb Avraham Yitzchak, and Leah bas Michal Mordechai.
1) MARKED ROCKS.
(a) R. Yehudah: If one finds a single rock with a lime mark on it, only
underneath it is Tamei. If two rocks are marked with lime, then: if the
space between them is also marked it is Tamei, if not, the space is Tahor.
2) WHEN THE BOUNDARIES OF THE FIELD ARE MARKED
(b) Question: A Beraisa says that the space between two marked rocks is
Tamei, even when the space itself is not marked (provided the space has not
been plowed over, in which case it is Tahor).
(c) Answer: The Beraisa is talking about a case where a bit of the lime goes
beyond the rocks, into the intervening space. If a plow has been there, we
may assume that the plow scraped some marking off the rock onto the adjacent
space, but the space itself was never actually marked. If there was no plow,
this possibility doesn't exist, so we must assume that the extra lime was
put there purposely to indicate that the space is Tamei.
(a) If one or two or three of the boundaries are marked, only that area (the
boundary itself) is Tamei. If all four boundaries are marked, the entire
enclosed area is Tamei (and the marked boundary itself is Tahor).
3) KIL'AYIM INSPECTION
(a) The Mishnah said that Kil'ayim inspectors go out on C.H. Pesach.
Question: This contradicts a Mishnah elsewhere that the inspectors go out on
(b) Answer: They go out both times, in Adar for early crops and in Nisan for
later crops (or in Adar for grain and in Nisan for vegetables).
(c) R. Yochanan: These times (15 Adar and C.H. Pesach) apply only when there
is no known, obvious Kil'ayim growing, but if there is, the inspectors go
out immediately, whenever it occurs.
(d) Question: Why was C.H. chosen as the time for this activity?
(e) Answer: Because labor is cheaper then.
(f) Deduction: The wages for the inspectors must come for the Terumas
ha'Lishkah, for if it would come out of the pocket of the individual farmer
we would not be so concerned to choose a time when the price is cheaper.
(g) Question: How much of the Kil'ayim has to be uprooted by the inspectors?
4) MISHNAH - TWO DISPUTES
(h) Answer: As the Mishnah (in Kil'ayim) says - until there is less than a
quarter Kav of growth per Se'ah of crop (a ratio of 1:24).
(i) Question: A Beraisa says that the WHOLE crop is expropriated.
(j) Answer: That Beraisa was taught after a Takanah was made, which took
this measure so that the farmer should not get free weeding service from the
(a) R. Eliezer ben Yakov: Water may be drawn from one tree to another
(although it is not necessary to prevent loss [it is a Beis ha'Ba'al], it is
permitted because it involves no exertion whatsoever - Rashi on Rif), but an
entire orchard may not be done this way (too much exertion). The Chachamim
disagree and permit the entire orchard.
5) GEMARA - DISCUSSION OF 4:b (according to most Rishonim, but not Rashi)
(b) R. Eliezer ben Yakov: Seeds that were not watered at all before C.H. may
not be watered on C.H. (they can easily wait). The Chachamim disagree and
(a) R. Yehudah: If the seeds are in moist ground, it is as if they had been
watered before C.H. and R. Eliezer ben Yakov permits watering during C.H.
(because the seeds begin to germinate, and will spoil if not watered).
6) BERAISOS ABOUT WATERING
(b) The Gemara brings a Beraisa (which contains the same exact two disputes
as the Mishnah - Tosfos) that confirms R. Yehudah's statement.
1. Ravina concludes from this Beraisa that it is permitted to lightly water
a garden on C.H., even though it is not for preventing loss but for
achieving a gain.
(a) Problem: One Beraisa says light watering is permitted (for a Beis
ha'Ba'al) on Shemitah but not on C.H. Another Beraisa says it is permitted
on both Shemitah and C.H.
7) BERAISA ABOUT WATERING BEFORE SHEMITAH
(b) Solution: The first Beraisa goes like R. Eliezer ben Yakov who forbids
watering for profit, permitting it only to prevent loss. The second Beraisa
is like the Chachamim, who permit watering for profit.
(a) Light watering is permitted (for a Beis ha'Ba'al) before Shemitah to
enable growth during Shemitah.
8) MISHNAH - TWO TOPICS
(b) Furthermore, this is permitted on Shemitah to enable growth after
Shemitah. (But watering ON Shemitah FOR Shemitah is forbidden - Rashi).
(a) One may trap moles and mice from a tree field (where they cause major
damage) or from a wheat field (where they cause minor damage), in the normal
manner, on C.H. and Shemitah. This is the opinion of the Tanna Kama.
Chachamim (or R. Yehudah) permit it for a tree field, but require a Shinui
for a wheat field.
9) GEMARA - EXPLANATION OF THE TERM ISHOS (MOLES)
10) BERAISA ABOUT DESTROYING PESTS
(b) One may repair a broken fence on C.H. (but not build a new one). On
Shemitah he may even build a new one.
(a) One may trap moles and mice, etc., as in Mishnah.
(b) One may destroy anthills (on C.H.).
1. How is this done? Raban Shimon ben Gamliel: Some dirt is brought from one
anthill and placed into a different anthill.
2. Abaye: This only works if the other anthill is on the other side of a
river without any bridge over it (so that the dirt is completely
unrecognizable to the new ants), and is more than a Parsah away.
