Rabbi Baruch Bodenheim: Gemara Eruvin: Second Perek, יום שלישי Nissan 29, Daf 24b (05/07/24)

Review “גמרא דף כד: “ההיא רחבה (seven lines from top of the Amud) until “הילכך” (four lines from bottom of the Amud) 

Questions:

Why is it prohibited to carry inside the רחבה? מבוי דמתא? שביל של כרמים? 

The Gemara attempts to present multiple solutions 

Placing a mechitza אגודא דנהרא – at the banks of the river

Placing a צורת הפתח by the פומא –  entrance of the שביל של כרמים

Placing a Lechi at the פתח – entrance of the שביל של כרמים

Placing a Lechi at the פתח – entrance of the מבוי דמתא 

How does each of these solutions permit one to carry inside each of the three areas? 

Why is it not a good solution?

Learn all the Tosfos on the Gemara. 

Clarify the questions Tosfos has on Rashi explanation of the various solutions. 

Tosfos presents a new explanation in the case of placing a mechitza אגודא דנהרא – at the banks of the river and placing a צורת הפתח by the פומא – entrance of the שביל של כרמים.

How do they differ from Rashi?
