Text Excerpt
מחלוקת שיש בה כדי חלוקה. אבל אין בה כדי חלוקה — דברי הכל מותר.
The dispute between R' Eliezer ben Ya’akov and the Rabbis is with regard to a courtyard where there is sufficient area in the courtyard for it to be divided into 4 square cubits for each partner, so each can be said to have a real portion that can be forbidden to the other. But if there is not sufficient area in it to be divided, everyone agrees that it is permitted to benefit from it, since the entire courtyard is viewed as belonging to both of them and each one can say that he is entering his own portion.
אמר ליה רב יוסף: הרי בית הכנסת, דכמי שאין בו כדי חלוקה דמי, ותנן: שניהן אסורין בדבר של אותה העיר!
Rav Yosef said to Rabba: A synagogue belongs to the entire public and is therefore considered like a courtyard in which there is not sufficient area in it to be divided, and we learned in a Mishnah later in the chapter (48a) that with regard to two people who vow not to derive benefit from each other, both are prohibited from deriving benefit from an entity belonging to that city such as a synagogue. Evidently, the Rabbis prohibit deriving benefit even from such entities.
אלא, אמר רב יוסף, אמר זעירי: מחלוקת שאין בה כדי חלוקה, אבל יש בה כדי חלוקה — דברי הכל אסור.
Rather, Rav Yosef said: Ze’eiri must have said: The dispute holds where there is not sufficient area in the courtyard for it to be divided, but if there is sufficient area in it for it to be divided, everyone agrees that it is forbidden, since if either enters it he may be entering the other’s portion.
אמר רב הונא: הלכה כרבי אליעזר בן יעקב. וכן אמר רבי אלעזר: הלכה כרבי אליעזר בן יעקב.
Rav Huna said: The halakha is in accordance with the opinion of R' Eliezer ben Ya’akov. And so too, R' Elazar said: The halakha is in accordance with the opinion of R' Eliezer ben Ya’akov.
