Chapter 6, Mishna 1
Three situations brought for clarification with respect to Shabbos and the law of eruv: 1) two houses separated by a public domain are enclosed in a new private domain by partitions erected by a non-Jew on Shabbos – may one of them renounce his rights in the new courtyard on Shabbos so that the other one may carry there? 2) courtyard of a non-Jew shares an alleyway with courtyards of Jews, but his courtyard also has a small private exit to a valley – must the Jews rent his rights in the alley in order to make an eruv for the alley? 3) baby needs warm water for an 8th-day circumcision to be performed on Shabbos, and there is no eruv – may we ask a non-Jew to bring the warm water (already heated) for us? In answering these questions, we get to know the subject of yesterday’s Meet the Mensch class, Rav Yosef, even better, as well as Rabba, Abaye, Rav Chisda and Rav Sheishes.
