(a) Rav Yosef says that, someone who urinates or spits from one major
Reshus to another will be Chayav.
But don't we require an Akirah from an
area of four Tefachim by four Tefachim?
(b) The source for this is a statement issued by Rava (or Rabah).
does *he* say?
(c) The Gemara asks what the Din will be if 'Hu bi'Reshus ha'Yachid u'Pi
ha'Amah bi'Reshus ha'Rabim', and the Sha'aleh remains unanswered.
are the two sides of the Sha'aleh?
(a) If a Kohen with Tamei hands who is eating a dried fig of Terumah,
places his hand in his mouth to remove a splinter of wood, Rebbi Meir
renders the fig Tamei, Rebbi Yossi says it remains Tahor.
What is the
basis of their Machlokes?
(b) What compromise does Rebbi Yehudah make, and why does this clash with
his own statement in our Mishnah, which prohibits walking into the street
with loose spittle in one's mouth?
(c) In its first answer, the Gemara replies 'Muchlefes ha'Shitah'.
does this mean?
(a) Resh Lakish disagrees with the previous answer. According to him, our
Mishnah is not referring to spittle, but to Kicho.
What is 'Kicho'?
(b) On what grounds does the Gemara reject Resh Lakish's answer?
(c) What does Resh Lakish learn from the Pasuk in Mishlei "Kol Mesan'ai
(a) Under what condition does the Tana of our Mishnah permit standing in
one major Reshus and drinking in the other, and why is that?
(b) Why is this not automatically considered making an Akirah in one
Reshus and a Hanachah (in one's stomach, which is in the Reshus
ha'Yachid) in another?
(c) Which Tana forbids carrying in the Reshus in which one is not
(d) Could the author of our Mishnah be the Chachamim who argue with him in
the previous Sugya?
(a) Abaye maintains that the same condition applies to drinking from a
Karmelis to a major Reshus, or vice-versa.
Answers to questions
What does Rava say to that?
(b) Abaye's proof is from the Seifa of our Mishnah 've'Chen be'Gas'. If
the Tana is not speaking about a wine-press that is a Karmelis, he argues,
then what is he adding to the Reisha?
How does Rava explain 've'Chen
(c) Rava's explanation follows the opinion of Rebbi Meir. Rebbi Eliezer
b'Rebbi Tzadok is more stringent.
What does *he* say?
(d) And what compromise do the Chachamim make?
(a) 'Kolet Adam min ha'Mazchilah Lematah me'Esarah Tefachim'.
What is a
'Mazchilah', and why is not permitted to drink from it directly or to
collect water from it directly - even when it is less than ten Tefachim
from the ground?
(b) 'u'min ha'Tzinor Mikol Makom'.
What is a Tzinor? In which way is it
Halachically different than a Mazchilah, and why is that?
(c) How does the Gemara prove Rav Nachman's explanation that Tziruf is
forbidden because of the principle of Levud?
(d) Is someone standing on a roof permitted to drink directly from his
neighbor's roof - if it is ten Tefachim higher than his?
(a) Our Mishnah permits someone who lives next to a Reshus ha'Rabim to
draw water via his first-storey window from a well in the street, provided
the well is surounded by a wall of ten Tefachim.
The Mishnah also permits throwing from the window on to a trash-heap. Why
are we not afraid that the trash-heap has been removed and is no longer
Why is the wall
(b) In which case is the wall dispensible?
(c) How does Rebbi Yochanan establish our Mishnah, by amending it
(a) Under which two conditions may one carry underneath the branches of a
