Today’s daf is sponsored by Deborah Schabes in memory of her mother’s yahrzeit, Judith Schoenfeld Schabes. Today’s daf is sponsored by Ilana Friedman in memory of Yosef Eliezer Ben Chaim whose shloshim recently passed. “He was a devoted Torah scholar and my best friend’s father – someone dear to my heart." If one is forbidden to benefit from another, they can benefit from public spaces that were made ownerless, but not from ones that are owned by the people in the city. What can be done to rectify this situation? If one cannot benefit from another but needs food, the other person can give the food as a gift to someone else, and then the one who is vowed not to benefit can take the food from them. However, a story is told of a son whose father couldn't benefit from him and the son was marrying off his own son and wanted the father to attend the wedding. He gifted his meal and courtyard to someone else and said that he was doing it in order to allow his father to eat. The person he gave it to did not like being used in order to allow them to go against their vow and therefore sanctified it all to the Temple. After this, the rabbis said that if one gives a gift in a limited manner that the other will not be able to sanctify it if they want, then it is not a valid gift. The Gemara brings a story of a father who vowed that his son not benefit from him, but then wanted to give his property to his son in order to give it to his grandson in the event that the grandson becomes a Torah scholar. Is this possible? In Pumbedita they ruled that it didn't work and Rav Nachman ruled that it did. Rav Ashi and Rava raised difficulties for Rav Nachman. He answered Rava's question with two possible answers.
