Today’s daf is dedicated by Yehudit Robinson in honor of Sarah Robinson, Mishna and Talmud teacher at Manhattan Day School. And by Navah Levine in honor of Rachel Levy. With appreciation to a most enthusiastic and encouraging chevruta. "Thank you for helping to keep me on this Daf Yomi Derekh. Happy birthday."
In order to permit carrying in an alley by using a side post or a cross beam, what is the minimum requirement of houses/courtyards in the alley? If this minimum is not there, the alley must be treated like a courtyard and either two side posts, one side post four handbreadths wide or a frame (tzurat hapetach) is needed. There are three opinions brought - by Rav, Shmuel and Rabbi Yochanan. The gemara first questions Rabbi Yochanan and also brings a different law of Rabbi Yochanan that matches his opinion here. Then they bring a difficulty for Shmuel - does he change his mind or not? Rav states a law regarding three houses that open to each other and only one opens directly to the alley. On the other side of the alley there is a gentile. One cannot make an eruv through the window of the inner houses. Why not? Would it be the same if they house of the Jew and the gentile opened up to a courtyard instead? Why would one think to distinguish between the cases?
