Study Guide Eruvin 75

Today’s daf is dedicated by Rabbi Rebecca Einstein Schorr in honor of the first yahrtzeit of her grandfather Dov ben Yitzchak Yaakov HaLevi v'Rayzel z"l. "He would be thrilled to know that his death inspired me to take on the commitment to Daf Yomi." And by Sara Berelowitz in memory of her father Zvi ben Moshe z"l on his 12th yahrzeit. He always had a Soncino Gemara with him until the Shteinzaltz came out.

The mishna brings various permutations of two courtyards - an inner and an outer - what if one does an eruv and one does not, or both make their own eruv or they make one together and one person forgets, or there is only one person living in the courtyard. What is the law in each case? The gemara introduces the concept of "one who is allowed/not allowed to walk in their space, do they forbid/permit one who is in a different space" - if the space is space that they normally walk through (the inner as it walks through the outer). In other words - does the fact that the inner can walk through the outer forbid the outer space (if they don't make one eruv together) or not, and if so, under what circumstances? Who holds what (Rabbi Akiva and the rabbis) and are there two opinions or three? Rav Dimi brings and interpretation of the rabbis in the mishna in the name of Rabbi Yannai. But the gemara raises several questions until Ravin brought a different tradition. The gemara brings a bratia to support a statement and in that braita is another debate between Rabbi Akiva and the rabbis is brought up regarding an inner and outer courtyard. Raba bar Chanan and Abaye try to understand what is the root of the debate. The mishna permits a case of individuals - what about a case of 3 people living between the two courtyards?
