Text Excerpt
קרפיפות רשות לעצמן. לדברי חכמים: גגין וחצירות רשות אחת, קרפיפות רשות אחת הן. לדברי רבי שמעון: כולן רשות אחת הן.
Similarly, enclosures are a domain in and of themselves, and one is therefore permitted to carry from one enclosure to another. According to the statement of the Rabbis, roofs and courtyards constitute one domain, and therefore, one may carry even from a roof to a courtyard; however, enclosures are one discrete domain. According to the statement of R' Shimon, all of them, roofs, courtyards, and enclosures, are one domain, and therefore it is permitted to carry between any of them.
תניא כוותיה דרב, תניא כוותיה דרב יהודה. תניא כוותיה דרב: כל גגות העיר רשות אחת הן, ואסור להעלות ולהוריד מן הגגין לחצר ומן החצר לגגין. וכלים ששבתו בחצר — מותר לטלטלן בחצר, בגגין — מותר לטלטלן בגגין, ובלבד שלא יהא גג גבוה עשרה או נמוך עשרה, דברי רבי מאיר. וחכמים אומרים: כל אחד ואחד רשות לעצמו, ואין מטלטלין בו אלא בארבע.
The Talmud comments: A baraita was taught in accordance with the opinion of Rav, and a baraita was taught in accordance with the opinion of Rav Yehuda. The Talmud elaborates. A baraita was taught in accordance with the opinion of Rav, that according to the Rabbis one may carry only 4 cubits on each roof: All the roofs of a city are one domain, and it is prohibited to carry objects up or carry them down, from the roofs to the courtyard or from the courtyard to the roofs. And with regard to vessels that were inside a courtyard when Shabbat began, it is permitted to carry them in the courtyard even if an eiruv was not established, and it is likewise permitted to carry them from that courtyard to other courtyards. With regard to vessels that were on the roofs when Shabbat began, it is permitted to carry them on the roofs, provided that one roof is neither 10 handbreadths higher nor 10 handbreadths lower than the other. This is the statement of R' Meir. And the Rabbis say: Each and every one of the roofs is a domain in and of itself, and one may move objects on each roof only within 4 cubits.
