Text Excerpt
והתנן מי שנתן רשותו והוציא, בין בשוגג בין במזיד — אוסר, דברי רבי מאיר.
But didn’t we learn elsewhere in the Mishnah: If one gave away his rights in his courtyard to the other residents of the courtyard, renouncing them after having forgotten to establish an eiruv with them the previous day, and then he carried something out from his house into the courtyard, whether unwittingly or intentionally, he again renders it prohibited for all the residents of the courtyard to carry; this is the statement of R' Meir. This indicates that according to R' Meir, even if the resident carried something into the courtyard on Shabbat itself, he cancels his renunciation, contrary to R' Meir’s own statement in the Mishnah with regard to a Sadducee.
אמר רב יוסף: אימא ״אינו אוסר״. אביי אמר, לא קשיא: כאן — שהחזיקו בני מבוי במבוי, כאן — שלא החזיקו בני מבוי במבוי.
Rav Yosef said: Say that R' Meir’s statement should read instead: He does not render it prohibited. Abaye said: It is not difficult, as the contradiction between the two teachings of R' Meir can be resolved as follows: Here, where the Sadducee cannot cancel his renunciation, it refers to a case where the residents of the alleyway had already taken possession of the alleyway before he brought out his vessels; whereas here, where the Jew cancels his renunciation, it refers to a case where the residents of the alleyway had not taken possession of the alleyway prior to his act of carrying.
והתניא: עד שלא נתן רשותו, הוציא בין בשוגג בין במזיד — יכול לבטל, דברי רבי מאיר. רבי יהודה אומר: בשוגג יכול לבטל, במזיד אינו יכול לבטל.
And similarly, it was taught in a baraita: With regard to one who failed to join in an eiruv with the other residents of his alleyway, if he carried something from his house into the alleyway before he gave away, i.e., renounced, his rights in the alleyway, whether unwittingly or intentionally, he can still renounce his rights; this is the statement of R' Meir. R' Yehuda says: If he unwittingly carried from his house into the alleyway, he can still renounce his rights, but if he did so intentionally, he cannot renounce them, for one who publicly transgresses the words of the rabbis and intentionally desecrates Shabbat has the status of a non-Jew.
