Today's daf is sponsored by Batsheva and Daniel Pava. "Eighty-one years ago, on bet Sivan, the deportation of Hungarian Jewry to Auschwitz began. May our learning be dedicated to the memory of my great-grandmother, Raizel, my grandmother, Batsheva bat Yisroel, the Steinmetz and Vegh families of Apsha, and all the Jews of Marmarosh who were murdered in Auschwitz. May their memories be a blessing."

Rava rules that one who takes an oath to not eat a loaf of bread, even if they have already eaten most of it, as long as there is still an olive bulk of bread left, the person can go to a chacham to repeal the oath retroactively. How can this case work with both the language of "I will not eat any of it" and "I will not eat it in its entirety"?

A source is brought regarding a nazir to raise a contradiction to Rava. However, it is resolved in three possible ways.

Ameimar disagrees with Rava and holds that one has even longer to repeal the oath, as long as the punishment has not yet been implemented.

Rava explains that if an oath is made with a condition, if the condition is fulfilled without intention, the oath does not take effect. If the person remembers the condition but forgets the oath when eating the forbidden item, one is liable to bring a sacrifice. If the person remembers both the condition and the oath when eating both, and first eats the one fulfilling the condition, they will receive lashes. If the person first eats the forbidden one and then eats the one fulfilling the condition, it is a debate between Rabbi Yochanan and Reish Lakish regarding a warning given in doubt, hatraat safek.

Rava continues with another case where a person said that each item is forbidden on condition that they eat the other item. He discusses four possible permutations of what the person did unintentionally and intentionally and explains the law in each case.

Rav Meri brings support from a Mishna and braita for Rava's principle in the above cases that if the condition is fulfilled unintentionally, the oath does not go into effect.

Avimi asks his brother Eifa about the ruling in different cases of a double/overlapping oath. Each time Eifa answers, Avimi disagrees with Eifa's ruling.
