The גמרא דף יא until the two dots on דף יא עמוד ב brings the opinion of רב that a צורת הפתח can not close an opening wider than 10 Amos. 

Rav Yosef understands that רב would also disqualify multiple צורת הפתח on openings less than 10 Amos if there are more openings than closures – פרוץ מרובה על העומד.  The Gemara tries to prove this position but is unsuccessful. 

The Gemara also attempts to bring a proof that ר’ יוחנן agrees to the opinion of רב that a צורת הפתח can not close an opening wider than 10 Amos but does not have a source. 

How do we conclude l’halacha?

Learn רמב”ם ה’ שבת פרק טז הלכה טז 

Note how the Ramabam rules

Major Question:

The Rambam concludes that each situation individually a צורת הפתח is valid. However when both are combined in a case of an opening wider than 10 Amos and פרוץ מרובה על העומד than it is disqualified.  

If each situation independently is valid, why is the combination deadly?

Our Gemara said the source to disqualify a צורת הפתח  when there are more openings than closures – פרוץ מרובה על העומד is from the halacha of Rav who rules a צורת הפתח can not close an opening wider than 10 Amos. Since the Rambam concludes a צורת הפתח is valid on an opening wider than 10 Amos where is the source to disqualify it when there is  פרוץ מרובה על העומד ?

Question on “רש”י “אלא ראשון:

Why should the fact that the Mitzvah of Daled Minim on the second – seventh day of Sukkos is only in the Beis Hamikdash be a reason that the Rabanan should allow a gezeira to not perform the Mitzvah?

Learn תוספת “הא

Chakirah: Is the mitzvah of Daled Minim all seven days of Sukkos in the Beis Hamikdash – an extension of the Mitzvah of Daled Minim of the first day obligation everywhere or an independent mitzvah? Think of a נפקא מינה between the two options

Note: how the בעל המאור explains different than תוספת “הא and avoids the major question we asked on Tosfos 

How could Tosfos suggest limiting the Daled Minim for the seven days of Sukkos which coincide with Shabbos to one’s home?  The only mitzvah for the rest of Sukkos is in the Beis Hamikdash?

Question: Are the disqualifications of the Daled Minim in the Beis Hamikdash all seven days the same as those of the first day of Sukkos?

There is an argument between Tosfos and the Ramban whether the requirement of לכם – to own the Daled Minim – applies for the Daled Minim for the entire Sukkos in the Beis Hamikdash

Quickly review the גמרא דף מב עמוד ב from after the Mishna until “אמר רבה”

Question:

Is an article that it’s functionality is exclusively for the purpose of a mitzvah (for example – lulav) considered muktzah?

We learnt “תוספת “טלטול that although it’s function is for a mitzvah since the item is not essentially a kli it is muktzah therefore Daled Minim are muktzeh on Shabbos.

We learnt a machlokes between the Rema and the Taz as to what category of muktzah is a Lulav on Shabbos of Sukkos

(See שולחן ערוך ורמ”א אורח חיים ס’ תרנ”ח סעיף ב and ט”ז ס”ק ג and משנה ברורה ס”ק ד and שער הציון אות ג)

https://hebrewbooks.org/pdfpager.aspx?req=60391&st=&pgnum=262

Rema – Muktzeh like a rock – מוקצה מחמת גופו

Taz – equates Lulav to a Shofar which has status of a כלי שמלאכתו לאיסור which is permitted to be moved לצורך גופו ומקומו

Major Question:

The gemara inquires whether an אמלתרא would help a Korah be a valid Tikun for a Mavui whose opening is wider than 10 Amos. The Gemara (3a) said the benefit of an אמלתרא is that it attracts attention and makes the Korah noticable therefore a Korah with an אמלתרא can be placed higher than 20 Amos. An opening wider than 10 Amos is considered a Pirtzah. How could an אמלתרא help for an opening wider than 10 Amos as the issue is entirely different?

Major Question:

Learn רש”י דף מב. “קא משמע לן which explains the chidush of the Mishna דף מב עמוד א that although there is no Mitzvah for women to take the Daled Minim they may still handle them on Yom Tov. Rashi explains the reason why it is not muktzah for women is since the Daled Minim are suitable for men therefore it’s considered a kli for women and are not muktzah. 

Our Gemara clearly contradicts this as our Gemara says the Daled Minim are muktzah?

Conclusion of אתי אוירא מהאי גיסא ואוירא מהאי גיסא ומבטלה 

Question:

In the case of עור העסלא (on bottom of דף י עמוד ב) if the total width of the seat is one tefach it is an אהל לטומאה. We discussed earlier a concept of אתי אוירא מהאי גיסא ואוירא מהאי גיסא ומבטלה. Why when the space between the two solid planks is equal or larger than the solid part don’t we apply the rule of אתי אוירא?  The solid part of the seat should be negated and no longer considered an אהל לטומאה ?

Sugya: אמלתרא

Major Question:

The gemara inquires whether an אמלתרא would help a Korah be a valid Tikun for a Mavui whose opening is wider than 10 Amos. The Gemara (3a) said the benefit of an אמלתרא is that it attracts attention and makes the Korah noticable therefore a Korah with an אמלתרא can be placed higher than 20 Amos. An opening wider than 10 Amos is considered a Pirtzah. How could an אמלתרא help for an opening wider than 10 Amos as the issue is entirely different?

See ב”ח ס’ שס”ג סעיף כו

And שפת אמת דף ג. לא תהני

How do we conclude l’halacha regarding whether an אמלתרא can help for an opening wider than 10 Amos?
