(a) What will the Din be of someone who separates more than one tenth from
his crops, as Ma'aser Rishon?
(b) Will this also apply if someone separates too much for Terumah?
(c) Why do we not apply here the principle of 'Kol she'Eino be'Zeh Achar
Zeh, Afilu be'Bas Achas Eino'?
(d) Why then, if two animals enter the pen simultaneously, are both
animals Ma'aser Beheimah, seeing as it is not possible to Ma'aser them in
halves? Why do we not apply the principle of 'Kol she'Eino be'Zeh Achar
(a) What does one do with the eleventh animal, if he declared the tenth
animal to be the ninth, and the eleventh, the tenth?
(b) There are six differences between Ma'aser and Shelamim: the latter
require leaning his hand on it, a drink-offering (incorporating flour),
waving it, the chest and the right calf are given to the Kohen. The former
What are the other two?
(c) What does one do in the case where he declared the two animals to be
the tenth, simultaneously, where he does not know which one is Ma'aser and
which Shelamim, with regard to ...
- ... leaning and waving the chest and the right calf?
- ... the drink-offering?
(a) How many loaves are needed to accompany a Korban Todah?
Answers to questions
(b) What is the status of the second set of loaves, if the owner Shechted

designated the loaves, he designated another forty?
(c) What does Chizkiyah hold in a case where someone Shechted his Todah on
(d) How does Rabah (the author of 'Kol she'Eino be'Zeh Achar Zeh' etc.
explain Chizkiyah's ruling? What are the three possible ramifications of
designating eighty loaves?
(a) According to Abaye, Rav only said that according to Rebbi Meir he is
not Koneh at all, by a tree whose branches span twelve Amos or more, but
less than that, he will be Koneh Shevisah.
Why is that?
(b) What is Rav Huna Brei de'Rav Yehoshua's objection to that?
(c) So how does *he* qualify Rav's ruling?
(a) Based on a Beraisa that supports him, in which case will Rav agree
that (even according to Rebbi Meir) one is Koneh Shevisah from a distance,
even by an area that is more than eight Amos wide?
The Beraisa quoted in the previous question (see c.3) appears to conform
with Rav. How does Shmuel (who says that, even though he is not Koneh
Shevisah beyond the tree, he *is* Koneh Shevisah underneath it) reconcile
it with his opinion? Why is he not Koneh Shevisash, even if he fixes his
residence in an undefined spot (e.g. under a tree)?
(b) What is the difference in this regard, between an area which is less
than a Beis Sasayim and one which is more?
(c) What should two travelers do, if only one of them recognizes a certain
spot within two thousand Amos of the point where they are standing, and
from their house, which is two thousand Amos beyond it in the opposite
(a) The Gemara also quotes a Beraisa in support of Shmuel: What does the
Beraisa say with regard to two servants for example, who placed an Eruv on
behalf of their master, one in the north, and the other, in the south?
Answers to questions
(b) How does this Beraisa clash with Rav?
(c) How will Rav reconcile it with his own opinion?
