Pictures Study Guide Eruvin 73 Today's daf is sponsored by Arlene Sevrinsky in memory of her father, Mordechai ben Avraham z"l on his yahrzeit. He taught us to love family, torah, learning and music. May his neshama have an aliyah. And by Hannah and Michael Piotrkowski in memory of Hannah's mother, Tsina Tova bat Leib Yisroel z"l on her 50th yahrzeit. She valued humility above all and is more loved and remembered as the years pass. What is the determining factor regarding eruv - where one sleeps or where one eats? If a man has a number of wives who each live in their own house, are they considered one unit for eruv or separate units? What about slaves? A student at his rabbi's house if he sleeps and eats there? Can one view a father and children or a rabbi and student as one unit for certain laws of eruvin and as separate units for others (in order to be lenient)? The mishna brings a number of cases regarding courtyards that open to each other and also to a shared alley.

The gemara struggles to understand the mishna as it seems to side on different sides of the Rabbi Meir/Rabbis debate regarding can one suffice with only one of the two.
