Rabbi Baruch Bodenheim: Gemara Shabbos: Third Perek – Monday night shiur Teves 21, Daf 37a (01/20/25)

Review the גמרא דף לז. “איבעיא להו until “ת”ש (fifth wide line) until 

גמרא דף לח. “איבעיא להו (twelve lines from bottom of the Amud) 
Question: Is the question of the Gemara whether סמיכה is permitted by שהייה or by חזרה? Learn תוס’ “מהו
If the question of the Gemara is in regards to חזרה what is the proof from the braissa which only discusses שהייה?
Learn רי”ף which brings a proof from this question that the halacha is like רבנןLearn רשב”א for a different explanation of the question of the Gemara 

Clarify the three explanations of the Gemara question 

1. Tosfos 

2. Rif

3. Rashba 

Review the first half of תוס’ “אא”ב and continue learning the rest of Tosfos 

Questions:

What’s the point of argument between Rashi and Tosfos?

What compelled Rashi to explain differently than the simple explanation offered by Tosfos? 

How can Rashi answer the questions of Tosfos?
