The gemara brings a case in which Raba bar Rav Chanan acquires residence from afar from his house without going to the location. Abaye questions his actions based on the conclusions reached at the end of the previous section and Raba changes his behavior. If one acquires residence with food, does one get in addition to the 2,000 cubits' also 4 cubits like in the case where one is there physically or not? The mishna brings a case of one who went to put an eruv but got called back by someone. The eruv works anyway for that person but not for the people of the city, according to Rabbi Yehuda. What exactly is the case? Why is there a difference between the person and others? Does the person need to make a declaration or is the intent clear without a declaration? Rabbi Meir doesn't allow this - however the person is only allowed to walk in the space that is common to one's house and the place where one intended to put the eruv. Rabbi Yosi son of Rabbi Yehuda has a different, more lenient approach. Raba and Rav Yosef disagree as to how he differs from Rabbi Yehuda's approach. If one leaves the techum by one or two cubits, is one allowed back in? What if one foot is in and one is out? Are the limits the surveyors put up at 2,000 cubits around the city exact or do they make them less than 2,000 to make sure people don't err? What is the relevance of this for one who hasn't reached the techum before Shabbat? How does one measure from around the city in the event that there aren't walls and all the houses don't line up in an exact straight line?
