Ask A Question on the daf

***************GIRSA SECTION********************
We recommend using the textual changes suggested by the Bach, Rav B. Rensburg and the parenthetical marginal notes of the Vilna Shas. This section is devoted to any *OTHER* changes that we feel ought to be made in Gemara, Rashi or Tosfos.)

[1] Tosfos 4a DH v'Ha Ba'inan:
The words *Darshinan* b'Eiruvin
should be *d'Darshinan* b'Eiruvin

[2] Gilyon ha'Shas 4a (the second one)
The words Lo Hevi Hasra'as Safek, Keivan *d'Mechusar* Ma'aseh
should be Lo Hevi Hasra'as Safek, Keivan *d'Lo Mechusar* Ma'aseh
************************************************

1) [line 4] L'CHI TEICHUL ALAH KURA D'MILCHA - (a) when you will measure out for me (i.e. pay me) a Kur of salt I will explain it to you;
(b) even if you consume a Kur of salt, you will not be able to equate them

2) [line 24] AKIRAH V'HANACHAH ME'AL MAKOM ARBA'AH AL ARBA'AH See Introduction to Maseches Shabbos, #4. In general, the creative acts that the Benei Yisrael did in order to build the Mishkan in the desert are the Avos Melachos.
(a) RASHI learns that the Melachos of Shabbos must be done in a proper, meaningful fashion. Therefore, with regard to the Akirah and Hanachah of an object, it is required that the object be taken from and placed upon an area that is at least four by four Tefachim;
(b) RABEINU TAM, cited in TOSFOS DH v'Ha, believes that the Melachos of Shabbos are solely dependent upon the building of the Mishkan. In modern times, we do not find that people place their objects on an area that is less than four by four Tefachim. This was probably the case in the Mishkan, also. Therefore it is a requirement for Akirah and Hanachah.

3) [line 26] HA'ZOREK ME'RESHUS HA'YACHID LI'RSHUS HA'YACHID U'RSHUS HA'RABIM BA'EMTZA
When a person throws an object from one Reshus ha'Yachid to another Reshus ha'Yachid through an intervening Reshus ha'Rabim, Rebbi Akiva rules that this person has violated Shabbos mid'Oraisa, while Rabanan argue. To explain their argument, two possibilities exist:
(a) If the object was thrown *below* ten Tefachim, Rebbi Akiva rules that we say Kelutah k'Mi she'Hunchah Damya (see below, #4). Rabanan rule that we do not use this Halachic assumption. Both Rebbi Akiva and Rabanan rule that if he threw the object *above* ten Tefachim, he would be Patur, since we do not learn Zorek from Moshit (see below, #5).
(b) The object was thrown *above* ten Tefachim. Rebbi Akiva learns Zorek from Moshit, and the person has violated Shabbos mid'Oraisa. Rabanan do not learn Zorek from Moshit. Both Rebbi Akiva and Rabanan rule that if the object were thrown *below* ten Tefachim, the person is guilty, since we say Kelutah k'Mi she'Hunchah Damya (See Introduction to Maseches Shabbos #3).

4) [line 28] KELUTAH K'MI SHE'HUNCHAH DAMYA
A person who throws an object from one Reshus ha'Yachid to another Reshus ha'Yachid through an intervening Reshus ha'Rabim is guilty of violating Shabbos mid'Oraisa, according to Rebbi Akiva. One explanation of his opinion is that the object is "caught" by the air of Reshus ha'Rabim below ten Tefachim and is considered Halachically at rest on the ground. The person has done an Akirah in Reshus ha'Yachid and a Hanachah in Reshus ha'Rabim, and is guilty of Hotza'ah.

5) [line 5] LO YALFINAN ZOREK MI'MOSHIT - Moshit involves passing an object from one Reshus ha'Yachid (e.g. a balcony) to another Reshus ha'Yachid through an intervening Reshus ha'Rabim. If we do not learn Zorek (throwing) from Moshit (passing), Zorek will not apply above ten Tefachim, since the prohibition of Moshit only applies above ten Tefachim. Normally, the air above ten Tefachim in Reshus ha'Rabim is a Makom Petur (See Introduction to Maseches Shabbos, #2d). Moshit parallels the actions of the Levi'im who took apart the Mishkan in the desert. They passed beams from one Reshus ha'Yachid to another Reshus ha'Yachid *above* ten Tefachim, as described in the Gemara Daf 98.

6) [line 13] HAI REBBI? - which [teaching of] Rebbi?
7) [line 13] ZIZ - usually a piece of wood that projects from a wall
8) [line 15] SHADI NOFO BASAR IKARO - the branch is considered to be four by four Tefachim since it is attached to the trunk (lit. throw the branch after the trunk)
