About this episode
Pictures Study Guide Eruvin 77 Today's daf (עז) is dedicated by Shelley and Jerry Gornish in memory of Oz Wilchek z"l, "our עז - our beloved and greatly missed grandson." How tall a wall is considered a separation between two courtyards that they would not be able to make an eruv together? If the wall is four handbreadths wide, each courtyard can access items at the top of the wall but cannot bring them down to their courtyard as the wall is a private domain in and of itself. What if the wall were less than four wide? Can one bring items from their courtyard to the wall as it is considered an exempt domain? What if the wall is ten high to one courtyard but lower for the other (as the ground of that one is higher)? The gemara brings various cases where one tries to lower the height of the wall, meaning to make it more accessible - either by lowering the wall itself or putting something on the floor to allow easier access. Does this mean that one can now use the wall as it is considered lower than ten? The gemara brings several different cases including ladders and other items.
