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.


PARTNERS BUILDING A DIVIDING WALL (Yerushalmi Halachah 1 Daf 1a)

משנה השותפין שרצו לעשות מחיצה בחצר בונין את הכותל לאמצע


(Mishnah): When partners want to divide their field by making a wall, they should build the wall in the middle (with both of them paying half of the cost).

מקום שנהגו לבנות גויל גזית כפיסין ולבינים בונים הכל כמנהג המדינה


In a place where the custom is to build with unshaped rocks; with carved rocks; with half bricks (1 1/2 tefachim thick), or with full bricks (3 tefachim thick), they should construct it with them. Everything follows the custom of the place.

בגויל זה נותן שלשה טפחים וזה נותן שלשה טפחים


For a wall of unshaped rocks, each gives 3 tefachim of their land;

בגזית זה נותן טפחיים ומחצה וזה נותן טפחיים ומחצה


For a wall of carved rocks, each gives 2 1/2 tefachim of their land;

בכפיסין זה נותן טפחיים וזה נותן טפחיים


For a wall of half bricks, each gives 2 tefachim of their land;

בלבנים זה נותן טפח ומחצה וזה נותן טפח ומחצה


For a wall of full bricks, each gives 1 1/2 tefachim of their land;

לפיכך אם נפל הכותל המקום ואבנים של שניהן


Therefore, if the wall fell down, they both have equal share of the place and the stones.

גמרא היך תנינן תמן אין חולקין את החצר עד שיהא ארבע אמות לזה וארבע אמות לזה.


(Gemara) - Question: (The Mishnah taught that if the partners wish to make a wall, they may do so.) How could the later Mishnah teach - 'They may only divide a courtyard if each will receive 4 amos'.

אמרי תמן בשאין שניהן רוצין ברם הכא בששניהן רוצין


Answer: There, they do not agree that it should be built (as one of them does not wish to do so); here, they both agree to build it.

ואפילו תימר הכא בשאין שניהן רוצין רצה זה כופין לזה רצה זה כופין לזה.


Answer #2: One could even say that here, they also do not both agree, but if one wishes to build, we require the other one to agree.
