Pictures Study Guide Eruvin 91 Today’s daf is dedicated in memory of Rabbi Lord Jonathan Sacks, HaRav Yaakov Zvi ben David Aryeh, zt”l who passed away yesterday. His teachings of Torah and human values will be shared and valued for generations. May his memory be blessed and may his family be comforted among the mourners of Zion. Rav Yehuda delves into the opinions of Rabbi Meir, the rabbis and Rabbi Shimon and explains what there would hold about carrying from the various areas to each other - like roof to courtyard to enclosure. The gemara brings a proof to support Rav's view of the rabbis that one can only carry four cubits on the roof if it is adjacent to another. Rav disagrees with Shmuel and Rabbi Yochanan regarding whether Rabbi Shimon allows carrying between areas even in a case where the courtyard residents made a eruv or only in a case where no eruv was made? The gemara brings questions against each of the opinions.
