Chapter 3, Mishna 4
How Reb Shlomo Carlebach wrote the famous melody for Shabbat Shalom/Mizmor LeDavid. May we establish an eruv by placing food in a tree in the public domain? Nuances of this question include how high in the tree? How wide is the branch it’s resting on? How far from the trunk? What lies between the food and the trunk? Rebbi says that anything prohibited on Shabbos by Rabbinic decree is permitted at twilight of Shabbos because we rule leniently in cases of doubt. Do the Rabbis disagree?
