Questions:

Why does the drying of the water from the well cause the loss of the mechitzas?

The גמרא דף יז bring the opinion of אביי that says “הואיל והותרה הותרה – once an area was permitted to carry inside it at the beginning of Shabbos that area retains its status for the entire Shabbos. This is in contradiction to our Gemara that says the drying of the water in middle of Shabbos removes the permission to carry inside the פסי ביראות ?

Rabbi Baruch Bodenheim: Chanukah Sugya, Wednesday night shiur, Chanukah Day 7, Teves 2 (12/13/23)

Topic: Bracha on the lighting of the additional candles that are added each night of Chanukah 

Questions

On the 7th night of Chanukah person mistakenly thought it was the 6th night and lit only six candles. Afterwards he realized it is the 7th night. When he lights an additional candle does he make a bracha?

See בית יוסף ס’ תרע”ב בשם אורחת חיים

https://hebrewbooks.org/pdfpager.aspx?req=14268&st=&pgnum=602

See פרי חדש סוף ס’ תרע”ב “נשאלתי  

From the Pri Chodosh it seems clear one does not recite a bracha on hidur mitzvah

See מגן אברהם ס’ תרנ”א ס”ק כ”ה who quotes the Rambam that if one did not have in mind to light additional candles then one must make a bracha upon lighting the additional candle.

https://hebrewbooks.org/pdfpager.aspx?req=14327&st=&pgnum=399

How could one recite bracha on hidur mitzvah? 

If he only realized after the six candles went out should he make a bracha on lighting the seventh candle? 

See שו”ת רע”א תניינא ס’ י”ג

https://hebrewbooks.org/pdfpager.aspx?req=1162&st=&pgnum=10

https://hebrewbooks.org/pdfpager.aspx?req=1162&st=&pgnum=11

Why does the שולחן ארוך או”ח ס’ תרע”א סע’ ב bring the halacha of amount of candles to light each night only in accordance with the Mehadrin min Hamehadrin and not list the base halacha that only one candle is required to be lit in each home for each night of Chanukah?  

Is the obligation of Mehadrin min Hamehadrin based on Hidur mitzvah or a different concept?

https://hebrewbooks.org/pdfpager.aspx?req=14278&st=&pgnum=374

What is the reason for the Mehadrin min Hamehadrin according to the Rambam?

How could one be obligated to light according to the Mehadrin min Hamehadrin and one has to spend  over 400% more to purchase 36 candles than the base obligation of eight candles?

Why isn’t adding candles considered a violation of baal tosif? If one would add extra mezuzahs on his door post for the amount of people in the house that would definitely be a violation of baal tosif.

We find the concept of Hidur in regards to enhancing a mitzvah. Ie. Purchasing a nicer Sukkah , talis,  … Where do we find the concept of Hidur that requires one to add additional mitzvahs?

Very quickly review גמרא דף מו: “מיד תינוקות (two dots, six lines from top of the Amud) until “א”ר זירא” 

We discussed how the Ran answered the following questions 

Questions:

1. Why are Daled Minim לא חזי בין השמשות?

Ran – one would not shake the Daled Minim during Bein Hashmashos between the seventh and eighth day of Sukkos as starting from day two they are a Mitzvah Drabanan and the rule is ספק דרבנן לקולא

2. Why according to ר’ יוחנן are Daled Minim  Muktzah the entire seventh day?

Ran – The mind frame of a person is to designate them for the entire seventh day as the mitzvah can be performed any time of the day. 

3. Does the Muktzah status of the Daled Minim of the seventh day extend into Bein Hashmashos? Why or why not? 

Ran – no as one would not take the Daled Minim during Bein Hashmashos as explained above. 

(See ריטב”א דף מו: א”ר יוחנן (first explanation) for a more elaborate explanation of the gemara according to the reasoning of the Ran.  https://www.sefaria.org/Ritva_on_Sukkah.46b.1?vhe=Chiddushei_HaRashba,_Sheva_Shitot,_Warsaw,_1883.&lang=bi

Questions

Everyone agrees that a Sukkah is Muktzah even on the eighth day (Shemini Atzeres). 

The Gemara explains the reason is that the Sukkah is needed during the period of Bein Hashmashos between the seventh and eighth day. 

Why does that give the Sukkah the status of Muktzah for the entire eighth day?

The Gemara says that Daled Minim are not needed during the period of Bein Hashmashos between the seventh and eighth day. 

Why not? 

Would the same be true if someone did not yet fulfill his Mitzvah with the Daled Minim on the seventh day?

Bring a proof from תוס according to which of the three explanations of the first inquiry of אביי he is aligned with.

The Gemara quotes ר”י who says there is a difference in size of gaps between פסי ביראות (allowed 13 1/3 Amos) and מחיצות (allowed 10 Amos). This contradicts what ר”י said in the first Mishna that the fourth side of a mavui can have gap of 13 1/3 Amos?

Question:

Why is it necessary to view the תל המתלקט as carved out in order to be an acceptable דיומד? Why is it not sufficient the fact that their is an Amah of a mechitza on each side?

Why does a round pillar need to be viewed as carved out and squared in order to be an acceptable דיומד? Why does it matter that the outside face plate is round? (See שפת אמת)

There are two approaches to answer these questions

Summary

We learnt three approaches to explain what the inquiry of אביי whether one may reduce the size of the opening between the פסי ביראות by extending the דיומדין? 

1. Rashi & the ח’ ר”ן – Adding פשוטין /middle panels is noticable that it was placed there to reduce the size of the gap which is not as clear by just extending the דיומדין. 

2. The ריטב”א – Adding פשוטין /middle panels is more preferred than extending the דיומדין when the width of the enclosed space between the פסי ביראות are less than 20 Amos as the פשוטין will divide the gap in half making each gap smaller than 10 amos. 

However when the width of the enclosed space between the פסי ביראות is more than 22 Amos extending the דיומדין is preferred as that will result in עמוד מרובה – more solid walls than gaps on each side. 

The question of אביי is whether ר”מ required פשוטין as most times it is more beneficial as the width of the enclosed space between the פסי ביראות is usually less than 20 Amos

3. The ח’ מהר”ל – perhaps extending the דיומדין although it physically reduces the size of the gap is insufficient as the concept of פסי ביראות is four corners composed of an אמה for each panel with a maximum of 10 Amos gap in between.
