About this episode
Study Guide Shevuot 19 Rabbi Eliezer and Rabbi Akiva disagree about how to extrapolate the verse in Vayikra 5:2. Chizkiya explains the difference of opinion between them, while Rabbi Yochanan and Rav Sheshet hold that they do not disagree, rather each exempts one who forgot the Temple or sacrificial items from bringing a sacrifice, but extrapolates it from different words in the verse. Rava asks Rav Nachman: if forgetting the Temple or sacrificial items does not obligate one to bring a sacrifice, what if one forgot both the Temple and that one was impure? Rav Nachman answers that since the person also forgot they were impure, of course there is an obligation to bring a sacrifice. But Rava retorts that perhaps since one who forgets the Temple is exempt, this person would be exempt as well. Rav Ashi suggests an answer to this deliberation, but Ravina rejects it. A case is brought of one who walked on two paths - one pure and one impure and went into the Temple. Two variations are brought and there is a debate about the halakha in each case. There are three different opinions regarding these three cases. What is the root of their debate? The issues raised here relate to what type of previous knowledge of impurity is necessary to obligate one for a sacrifice. Rabbi Yochanan and Reish Lakish each offer different interpretations for the first opinion in the cases of the two paths. Their opinions here contradict their opinions in a different place. How are these contradictions reconciled?
