Very quickly review the גמרא דף ח. “גופא אמר רב ירמיה בר אבא (two dots) until דף ח: “איתמר  (five lines from top of the Amud)

Rashi דף ח: “ולרבה has the words “ואפילו בחצר” in parentheses.  

Point to Consider:

Does a חצר  מפולש  have the same halacha as a מבוי מפולש?

See the מהרש”ל & מהרש”א & מהרש”א מהדורא בתרא (underneath the מהרש”א) who discuss why the חצר should also be prohibited.

Last week we learnt the גמרא דף ח. “מרימר פסיק לה לסורא באוזלי. Rashi learnt מרימר placed the nets on the end of the street before the sea. However the מגיד משנה explained according to the Rambam who rules we are not concerned for שמא יעלה הים שרטון the case was that מרימר placed the nets on the other open side of the street. 

Question on the מגיד משנה:

Rabbi Jaffe asked me the following question on Shabbos.

What was the need to place nets – a full wall on the fourth side as since the sea wall is a valid wall than this road is a classic dead end mavui which only requires a Lechi or Korah on the fourth side?

Learn the Gemara דף מ: “אמר ר’ אלעזר  (fifth line from top of the Amud) until תניא כוותיה” 

Questions

If one can not redeem produce from it’s kedushas shevis than how could the Gemara on דף לט instruct of one accidentally purchased fruits from an Am Haaretz on shmita the purchaser should redeem the kedusha from the money on to fruits in his home? 

Learn תוספת “אין and תוספת דף לט. “מעות 

According to ר’ אלעזר when one redeems kedushas shiviis does the money or item used for redeeming need to be the same value as the produce being redeemed? 

We pasken in the time when there is no Beis hamikdash one may redeem thousands of dollars worth of fruits of maasar sheini onto a lesser value coin. 

According to ר’ אלעזר when one redeems kedushas shiviis can a large amount of produce be redeemed on to a lesser value coin?
