BAVA BASRA 2-8 - Two weeks of study material have been dedicated by Mrs. Estanne Abraham Fawer to honor the Yahrzeit of her father, Rav Mordechai ben Eliezer Zvi (Rabbi Morton Weiner) Z'L, who passed away on 18 Teves 5760. May the merit of supporting and advancing Dafyomi study -- which was so important to Rav Weiner -- during the weeks of his Yahrzeit serve as an Iluy for his Neshamah.

1) THE REQUIRED THICKNESS OF THE WALL (Yerushalmi Halachah 3 Daf 2a)

עד כדון לארכו לרחבו

(a) Question: Until now we have discussed the height of the wall (that it must be four amos), what about the thickness?

א"ר נסא כותל חצר לא נעשה אלא להציל לו.

(b) R. Nasa: Since the purpose of the wall is to prevent hezek re'iyah (the damage of one neighbor peering at the other), the thickness only needs to be enough to prevent it.

סברין מימר שאם רצה לקרות אינו מקרה

(c) Question: Since no particular thickness was stated, the Chachamim suggested that even a very thin wall would therefore suffice. However, the problem is that it cannot support a roof, which is unlike the Mishnah?

א"ר יוסי בי ר' בון תיפתר על ידי מרישיו:

(d) Answer (R. Yosi bei R. Bun): Although its walls cannot support a roof, it could have strong beams that can support a roof.
