1)

(a) Why is it not necessary to search a yard for Chametz?

(b) In which kind of area may one use sunlight to search for Chametz - (if, for some reason or other, one was unable to search on the night of the fourteenth)?

(c) Then what is the Gemara referring to when it forbids searching for Chametz by sunlight?

(a) What do we learn from the Pasuk in Chavakuk "ve'Nogah ka'Or Tihye ... Karnayim mi'Yado Lo"?

(b) What Halachic proof do we have that a torch (consisting of two combined flames) is better than a single flame?

(c) Then why is it not Kasher for Bedikas Chametz (four reasons)?

(a) The Beraisa lists the places that do not require Bedikah (which are all derived from 'Kol Makom' in our Mishnah): Holes in the wall that are either very high or very low; sloping roofs; the tops of the cupboards. What else does the Beraisa include in the list?

(b) Raban Shimon ben Gamliel precludes the space underneath a dividing bed from the list.
How do we reconcile this with another Beraisa, where he appears to exempt the very same space from Bedikah?

(a) When does a wine-cellar require Bedikah, and why does an oil-cellar never require Bedikah?

(b) What Din did they give to a beer-storage room in Bavel?

(c) Which kind of fish-storage room requires Bedikah, and which kind does not?

(d) Do the following require Bedikah: a room where one stores ...

1. ... salt or wax?
2. ... wood or dates?

(a) The Beraisa exempts the searcher from stretching his hands deep into the hole in a wall, due to the element of danger involved.
Could this be referring to the danger of scorpions?

(b) The Gemara concludes that indeed it is indeed because of scorpions, but that we are speaking about a case when the wall had collapsed.
How do we reconcile this with the Mishnah, which exempts one from the need to destroy even known Chametz lying under a pile of rubble?

(a) 'Sheluchei Mitzvah Einan Nizokin'.
Would it be correct to say that this does not apply to searching a wall where there are scorpions for Chamtz, because, in the process of searching, one may also search for a needle that one dropped there (in which case he will not be fulfilling the Mitzvah)?

(b) Why then, *do* we contend with it?

7)

(a) According to Rav Nachman bar Yitzchak, the Beraisa is referring to the danger of gentiles, and the author is Pelimu.
What does this mean? What does Pelimu say?

(b) How does he use the holes in the first instance, (becaue, if he did not, he would not be obligated to search)?

(c) How do we now answer the Kashya from 'Sheluchei Mitzvah'?

(d) How does the Gemara prove this from Shmuel?

(a) What did Rav reply when they asked him whether the Talmidim who lived in the valley may go very early in morning and late in the evening to learn? How about the danger of demons?

(b)Were they permitted to return? From which Pasuk do we learn this?

(c) What 'Kal va'Chomer' do we learn from "ve'Lo Yachmod Ish es Artzecha"?

(d) Seeing as even on the return journey no harm will befall a Sheli'ach Mitzvah, why do we need the Pasuk "ve'Lo Yachmod Ish es Artzecha"?

10)

(a) What does the Gemara mean to ask when it says 'Martef Ma'an Dakar Shemei'?

(b) What is the answer?

(c) According to Rav Yehudah, the two rows that one is obligated to search in the wine-cellar (according to Beis Shamai), are the two complete *outer* ones? Rebbi Yochanan understands Beis Shamai to mean 'Ke'min Ga'am'.
What does *that* mean?

(d) Rav explains the 'Sh'tei Shuros ha'Chitzonos she'Hen ha'Elyonos' (of Beis Hillel) to mean the very top outer row and the one below it.
How does Shmuel explain it?
