Rabbi Baruch Bodenheim: Gemara Shabbos: Third Perek – Monday night shiur, Sivan 21 – Sugya Chazara – Daf 38a-38b (06/16/25)

Very quickly review the גמרא דף לח: “בעי רב אשי פינה ממיחם למיחם  (line before the Mishna) until the Mishna 

Question:

What is the uncertainty in the case of פינה ממיחם למיחם (transferring the food to a different pot) whether it is permitted to return the second pot to the stove?

Clarify how the explanation of רש”י “פינה is different than תוס’ “פינה 

Major Question:

Tosfos says there is a potential concern when one transfers hot food into a second pot that one might come to stoke the coals.  How could there be a חשש שמא יחתה when we are dealing with a stove that is גרוף וקטום?

Learn ר”ן דף יז: דפי הריף “בעי רב אשי for an additional two answers 

How are the two explanations of the Ran different than each other?

How are the two explanations of the Ran different than Tosfos? 

According to the Ran what is the Halacha in regards to returning the second kettle to the fire. Is it permitted or prohibited?

Halachic Conclusion:

What is the halachik conclusion of פינה ממיחם למיחם ?

The Ran says if one returns the contents back to the original pot it is possibly prohibited to return the pot to the fire as it is considered he placed the pot on the ground when placing it into the second pot. Why would this reasoning not prohibit returning the second pot itself to the fire?

See קובץ הלכות פרק כו הערה עג

According to the Mishna Berura is it permitted if the water is placed into a cup and then poured into the Crock-Pot?

See שמירת שבת כהלכתו פרק א הערה מט

According to the Magen Avraham is it permitted to add hot water directly from a hot water urn into a crock pot?

Why does the ר”י not like the explanation of Rashi?

How does Rashi explain why placing a pipe of cold water into the חמי טבריא is considered הטמנה?

Write out the three explanations of Tosfos as to why one may not use the water that was placed inside the חמי טבריא.

Questions:

The prohibition of submerging an egg in sand according to ר’ יוסי based on רבה – is to prevent a person from mistakenly concluding that one may submerge an egg inside רמץ on Shabbos.

Is it permitted to submerge the egg on Friday?

If yes then how is it comparable to the case of  immersing a pipe of cold water inside the חמי טבריא which was on Friday?

Does רב יוסף also agree there is a concern שמא יטמין ברמץ ?

See רש”י דף לט. “דשרי who says the reason it is permitted to cook something directly from the sun is because “אין דרך בישול בכך”

Major Question: 

We have a rule in הלכות שבת when a melacha is performed in an abnormal way it is exempt from Torah violation however it is still prohibited מדרבנן. So how could it be permitted to cook directly from the heat of the sun?

There are prohibitions of cooking in regards to other halachos. For example – cooking meat and milk together, cooking the Korban Pesach. 

If someone were to cook in the sun or a product that was heated by the sun would they be transgressing that prohibition?
