2. Question: Why does the Tur hold that Yochanan Ochel Challos did not have to divulge as part of his story that his father took him out of yeshiva?
A. Rebbe Yehuda HaNasi poskined that this person is a kohen based on the innocent story he gave of his childhood when he remembers his father carrying him on his shoulders and dipping him in the mikvah and then going to the threshing floor to collect teruma/tithes from the owners to eat in the evening, and hi friends would stay away from him and call me Yochanan Ochel Challos.
2. Tosfos holds that part of the story in Kesubos 56b was specifically that the father took him out of yeshiva and this was important so that it will rule out the possibility that he wasn’t a non-Jewish slave who can eat Teruma if his master is a kohen, but a non-Jewish slave cannot learn Torah so he wouldn’t be in Yeshiva. The Tur holds that the fact he was taken out of yeshiva was just part of the story but had no significance so he left it out.
C. Female non-slaves don’t get married so any children are out of wedlock and are automatically slaves to her master.
Answer: The Taz (Even HaEzer 2:1:1) says that we probably won’t know who the father is and even if we do the child should be with his master at all times so if he says his father carried him on his shoulders it must be the person talking is Jewish and according to his account that makes him a kohen.
