Pictures Study Guide Eruvin 66 Today's daf is dedicated in memory of Avraham Nachum ben Yitzchak Refael z"l on his yahrzeit. His dedication to Daf Yomi is an inspiration to his family, who continue in his footsteps. And by Debbie and Michael Schreiber in honor of our first grandchild Naomi Frumit to our children Yarden and Adam Schreiber of Jerusalem. May she flourish and grow and may her parents raise her to torah, chuppah and maasim tovim in a home that I know will be filled with love and simcha and Torah learning. Does Rabbi Yochanan really hold that one can make a rental arrangement on Shabbat with a gentile to allow carrying as happened in the situation at the inn? Didn't Rabbi Yochanan make a comparison between making an eruv (which can only be done on Shabbat) and renting from a gentile? The gemara explains the comparison as regarding other issues and not whether or not it can be done on Shabbat. Shmuel describes differences between cases where there are courtyards and one forbids or doesn't forbid the other and one can or cannot make an eruv with the other and concludes in which circumstances relinquishing rights would be permitted. One of his cases seems to be referring to the case in the inn with the gentile and Shmuel's conclusion contradicts Rabbi Yochanan who allowed relinquishing of rights in that case (after the gentile rented the space to them, they needed to relinquish their rights to one of the Jews as their eruv was nullified). The gemara delves more in depth into Shmuel's approach in some of the cases he mentioned which is based on the concept that relinquishing of rights from one courtyard to another is forbidden. Rava and Abaye disagree regarding the extent to which Shmuel said this? In which cases would be make exceptions?
