BAVA BASRA 82-85 - Sponsored by a generous grant from an anonymous donor.
Kollel Iyun Hadaf is indebted to him for his encouragement and support and
prays that Hashem will repay him in kind.
(a) Rav Yosef (who gave the maximum distance between two trees in a vineyard
as less than eight Amos) was not impressed with Abaye's Kashya (from the
Mishnah in Kil'ayim), because he relied on an incident that took place in
What does 'Dura di'Re'usa' mean?
(b) What did Rav Yehudah rule there regarding a man who purchased three
trees with a space of less than eight Amos between each two trees?
(c) Rav Yosef did not understand what he meant, until he learned a Beraisa.
What does the Tana there say to explain the Mishnah in 'Lo Yachpor', which
forbids a person to plant a tree within four Amos of his friend's pit?
(d) Why did Abaye query Rav Yosef on the basis of the Mishnah in Kil'ayim,
when Rebbi Meir and Rebbi Shimon, in the very same Mishnah, permit the
planting of seeds in a vineyard where there is a space of eight Amos between
the rows (like Rav Yosef)?
(a) We just cited the Mishnah where Rebbi Shimon (and Rebbi Meir) gives the
maximum distance of one row of vines and the other as less than eight Amos.
We know that the minimum Shiur is four Amos from another Mishnah in
What does Rebbi Shimon there say about a vineyard whose rows are
planted less than four Amos apart?
(b) On what grounds do the Chachamim disagree with him?
(a) And from where do we know that the minimum Shiur of the Tana Kama of
Rebbi Yehudah (in the Mishnah in Kil'ayim) is eight Amos?
(b) What are the minimum and maximum spaces allowed between one row of vines
in a vineyard and another, according to Rava?
(c) From where does Rava know to adopt the two extremes (like the smallest
Shiur of Rav Yosef and the largest of Rav Nachman (whom he himself quoted
(d) Whose opinion is Rava following?
(a) In the Beraisa that we quote in support of Rava, the Tana grants someone
who purchases three trees, the land in between and the trees.
What does he
mean by 'trees'?
(b) He then goes on to cite three cases where the purchaser of three trees
does not acquire the ground; two of them are when the trees are planted
within four Amos of each other or more than sixteen Amos.
What is the
(c) Rebbi Yirmiyah asks whether one measures the above measurements from the
narrow part of the tree or from the wide part.
If this does not refer to
the trunk up to the point where the branches grow and the tips of the
branches respectively, what does it refer to?
(d) Rav Gevihah from Bei Kasil resolves this She'eilah from a Mishnah in
From where does one measure a grafted vine (in connection with
the minimum four-Amah space between one vine and another, that determines
what is a vineyard)?
(a) He then asks what the Din will be in a case where someone purchased a
tree with three 'Badei Ilan'.
Why can this not refer to someone who
purchased three branches, one on each of three trees, and he asks whether we
go after the branches (and he acquires the ground too), or after the tree
(and he doesn't)?
(b) Then what *is* the She'eilah?
(c) Once again, Rav Gevihah resolves the She'eilah from a Mishnah in
What does Rebbi Eliezer b'Rebbi Tzadok rule there in a case where
someone bends three branches of three vines and transplants them in the
ground, after they took root?
(d) What connects Rebbi Yirmiyah's current She'eilah with Rebbi Eliezer
b'Rebbi Tzadok's Halachah?
(e) What constitutes a vineyard?
(a) Rav Papa asks what the Din will be if Reuven sells Shimon two trees in
his field and one on the border.
Answers to questions
What is his She'eilah? Why might Shimon
not acquire the ground?
(b) Then he asks what the Din will be if he sells him two trees in his field
and the third one in Levi's field.
What must Rav Papa assume with regard
to the previous She'eilah, for this She'eilah to have any meaning?
(c) What is the outcome of the two She'eilos?
(a) Rav Ashi asks whether a water-pit, a stream, a road or a cluster of
palm-trees will divide the three trees.
What sort of road is he talking
(b) What is the significance of the sequence of ...
(c) On what grounds do we query the She'eilah that Hillel (not Hillel
ha'Zaken) asked Rebbi regarding a cedar-tree that grew among the three trees
that Shimon bought?
- ... Rav Papa's She'eilos followed by those of Rav Ashi?
- ... Rav Ashi's four She'eilos?
(d) Then what was Hillel's She'eilah? And what did Rebbi reply?
(a) According to Rav, Shimon acquires the ground even if the three trees are
growing in a straight row.
What does Shmuel say?
(b) What is Shmuel's reason?
(c) If, as we just concluded, the criterion for acquiring the ground is the
fact that it is difficult for the owner to plow the ground in the middle, we
suggest that if Shimon purchased three large thorn-bushes from Reuven, he
would also acquire the ground, taking into account the difficulty of plowing
in between the bushes.
Would it make any difference whether they the
bushes were growing in the shape of a triangle or in a straight row?
(d) On what grounds do we refute this suggestion?
(a) Regarding the sale of certain limbs of a large species of animal (a cow
or a bull), what does our Mishnah say about Reuven who sells Shimon ...
(b) Will this ruling prevail even against local custom?
- ... the head? Does the sale incorporate the legs, or vice-versa?
- ... the lungs? Does the sale incorporate the liver, or vice-versa?
(c) How will the Halachah differ with regard to the sale of a small species
of animal (a sheep or goat)? What would be the Din there if he sold him ...
- ... the head or the legs?
- ... the lungs or the liver?
(a) The Tana then lists four Dinim concerning the validity of a sale. What
will be the Din if Reuven sold Shimon ...
(b) To which category does a case where Reuven sold Shimon olive-trees,
which turns out to be sycamore, or vice-versa?
- ... superior wheat, and it turns out to be inferior? Who is permitted to retract?
- ... inferior wheat, and it turns out to be superior?
- ... what he promised him, irrespective of whether it is inferior or superior?
- ... Shechamtis and it turns out to be white wheat, or vice-versa?
(c) Why, in the previous case (as well as where he sold him wine and it
turns out to be vinegar, does this belong to that category too, and not to
the first category in the Mishnah?
(d) Does the number 'four' come to preclude anything in particular (as it
(a) The first case (superior and inferior) is not one of Mekach Ta'us (a
false sale), but of Ona'ah.
Answers to questions
What principle governs who may retract?
(b) What distinction exists between this Din of Ona'ah and a regular case,
where only the price is involved?
(c) Why, in the case where Reuven gave Shimon ...
(d) What does 'Shechamtis' mean?
- ... inferior wheat, as he promised him, but then the price of wheat went down, might we have thought that Shimon can retract?
- ... superior wheat, as he promised him, but then the price of wheat went up, might we have thought that Reuven can retract?
