Sukkah 23a
Tamuz 19, 7581. June 29, 2021
1- We continued with controversial passage in the מהרי”ל about the אסמכתא concept. See previous shiur.
Thank’s to Dani Chitrik for the link to the discussion regarding the Problem with Likkutei Maharil – Mi Yodeya.
Another link with links to two scholarly articles about the above.
2- Surprisingly, the מגן אברהם writes explicitly that “if one hears a Halacha’ and it seems to him to be correct, he may tell others that ‘this Halachah was said by a great and accepted Rav’ if this will cause people to accept it!
See here: OC 156,
שמע דין ונראה לו שהלכה כך מותר לאמרו בשם אדם גדול כי היכי דליקבלי מיניה
[עירובין דף נ״א ופסחים דף קי״ב] ובסוף מסכת כלה איתא האומר דבר בשם חכם שלא גמרו ממנו גורם לשכינה
שתסתלק וכ״ה בברכות דף כ״ז ע״ש וצ״ע.

3- A sukkah on a truck.
Although the our Mishnah permits it the Pri Megadim, OC 628, 4, says that it is only Kosher while parked. A Sukkah atop of a moving truck or flat bed is not considered a proper Sukkah. The ביכורי יעקב disagrees.

We mentioned it seems from the Alter Rebbe 628, 4, that he would agree with the Pri Megodim.

That is interesting for all the Chabad Sukka mobiles.

4- We scratched the surface of the huge topic of אינו ראוי מדרבנן נקרא אינו ראוי מן התורה .
Such as a Sukkah on a tree top. מדרבנן one cannot climb on a tree on Shabbos or Yom Tov.

If however one does use this tree-top Sukkah, did he fulfill the מצוה? Or perhaps since the חכמים enacted their גזירה they uprooted this particular סוכה and one is not יוצא even מן התורה!
More on this topic BL”N next week.
5- Interesting question from the Maharil:
מדרבנן one cannot climb a tree or ride atop of an animal on Shabbos or Yom Tov.

Similarly, one is prohibited to read in front of a burning candle on Shabbos. The גזירה is that inadvertently he may adjust the flickering wick when needed.

However two people reading together may use a single candle to read since one will remind the other of the prohibition to adjust the wick.
Asks the Maharil; would this permit two people to climb a tree at the same time or riding an animal together?

See here the מגן אברהם OC 285, 5, that answers that the leniency of two reading by candlelight applies on when learning. It would not apply to joy riding or tree climbing.
So two people climbing a tree to eat in a Sukkah would be OK?
To be continued…
