The rabbis and Rabbi Elazar disagree about a case involving liability for performing water libations outside the Temple. Three amoraim debate the precise scenario in which they disagree and the underlying basis of their dispute. According to Rav Papa, their disagreement stems from a debate - found in other sources as well - regarding whether libations accompanied sacrifices during the Israelites' time in the desert. This question has practical implications for whether libations were ever offered on private bamot, and whether such libations required sanctified vessels. That, in turn, affects whether one would be liable for performing a libation outside the Temple when it was not placed in a sanctified vessel.

Rabbi Nechemia maintains that one is liable for offering the remainder of the blood outside. Rabbi Yochanan explains that this view is rooted in Rabbi Nechemia's position that the pouring of the leftover blood is an essential component of the sacrificial rite. A challenge is raised from a baraita in which Rabbi Nechemia debates Rabbi Akiva on this very issue, but the contradiction is ultimately resolved.

The sugya then analyzes liability for offering a bird sacrifice outside the Temple: does liability depend on whether the bird was slaughtered (shechita) or melika was performed inside or outside? All four possible combinations are examined. Rabbi Shimon disputes one of the rabbis' rulings, but it is initially unclear what aspect of their position he rejects. After systematically eliminating all possibilities, the Gemara proposes three explanations - either expanding the Mishna to include another case or revising the formulation of Rabbi Shimon's statement as it appears there.
