R. YOSI EXEMPTS FROM A CHATAS ONE WHO CARRIES A LULAV
(Abaye): R. Yosi's exemption applies only prior to fulfilling the Mitzvah.
Question: But there is never a point of carrying prior to fulfilling the Mitzvah, since one is Yotzei as soon as one picks it up!?
Answer (Abaye): R. Yosi was speaking where he picked it up upside down.
Answer (Rava): R. Yosi was speaking where one took the Lulav by means of a Kli.
Question: But Rava holds that indirect Lekichah is called Lekichah!?
Answer: That holds only in a respectable manner (like draping one's hand with a cloth).
OTHER EXAMPLES OF R. YOSI'S PETUR FOR TA'AH BI'DEVAR MITZVAH
(R. Huna): R. Yosi also exempted one who ate an Olah thinking it was a Chatas.
Question: That is not news, that is identical to the Petur of our Mishnah!?
Answer: We might have limited the Petur of Ta'ah bi'Devar Mitzvah to where he is presently fulfilling a Mitzvah (such as Netilas Lulav, but not eating the Olah, which is not a Mitzvah at all).
Question: But in the Beraisa R. Yosi teaches that one who accidentally slaughters an unchecked Tamid is Chayav!?
Answer: That is exceptional as it is close to Meizid (as that Beraisa has been qualified as speaking where he negligently took the animal from the unchecked pen).
MISHNAH: PROTECTING THE LULAV
A woman may return the Lulav to its water on Shabbos.
(R. Yehudah): It may be placed back in its water on Shabbos, but no water may be added, while on Yom Tov water may be added and on Chol ha'Moed the water may be changed.
A boy who knows how to wave the Lulav is obligated.
WOMEN AND LULAV
Question: Is it not obvious that she can handle the Lulav?
Answer: We might have prohibited her handling of the Lulav since she is not obligated it its waving it might be Muktzeh for her.
THE OBLIGATIONS OF A CHILD
The Beraisa lists the obligation point for Lulav, Tzitzis, Tefilin, Torah and Shema.
Question: What does his father teach him?
Answer: Torah Tzivah and the first Pasuk of Shema.
The Beraisa lists when a child's body does not render Tum'ah, when his hands do not create Tum'ah.
When doubts arise, a child who can answer when asked is Tameh in Reshus ha'Yachid and Tahor in Reshus ha'Rabim.
If he is established in Nesi'as Kapayim he may be given Terumah publicly.
If he is able to control the knife, he may slaughter (when he is under adult supervision- R. Huna).
Once he can eat a k'Zayis of grain his discharges are malodorous and Tefilah must be distanced from them (assuming that he can eat the k'Zayis within Achilas Peras- R. Chisda).
(R. Chiya bar R. Yeiva): One must distance oneself in prayer from an adult's discharges even if he presently cannot eat a k'Zayis within Achilas Peras (Pasuk).
Once a child can eat a k'Zayis of roasted meat he is included in the Korban Pesach.
(R. Yehudah): Once he can differentiate between edibles and non-edibles.
He throws away pebbles but takes nuts.
MISHNAH: THE FREQUENCIES FOR THE MITZVOS OF SUKOS
Lulav and Aravah are taken six or seven days (depending on when Shabbos falls).
Halel and Simchah are on all eight days (including Shemini Atzeres).
Sukah and Nisuch ha'Mayim are all seven days.
Instruments, like the Chalil, are used for five days of Simchas Beis ha'Sho'evah, (or six, if the first day is Shabbos).
The Lulav is taken seven days when the first day is Shabbos, while if it is on a different day of the week the Lulav is only taken six days (not on Shabbos Chol ha'Moed).
The Aravah is taken for seven days when the seventh day (Hoshana Rabah) is Shabbos (otherwise six days).
The Lulavim were brought Erev Shabbos to the Mikdash and were received by the Chazanim and placed on the Itztaba (while the elders used the Lishkah).
The People were taught to relinquish their ownership of their Lulavim in favor of whomever picked up that Lulav the next day.
The dangerous scuffle which ensued in the Mikdash when people went to claim a Lulav led Beis Din to order people to wave the Lulav at home, instead.
