This Shiur is on the Gemara that discusses the need for the Braissa on Daf 6:1 to say the punishment for carrying items from private to public domains or vice versa.
Rabbi Oster begins with analyzing the first Tosfos on the question.
Is Rashi and Tosfos arguing?
What about?
Where does their argument stem from?
Next Rabbi Oster analyzes Rashi’s stance on why the Megillah was hidden.
Was it wrong to write it down?
If yes, why did they?
Once you write it, why hide it?
These are just some of the points touched upon in this Shiur. Rabbi Oster also goes through various reasons why it is problematic to write it down and what truly the issue is.
