Today's daf is dedicated to Mimi and Rafi Schachat on the birth of a daughter!

Rava and Rav Ashi each pose a series of unresolved questions concerning the minimum duration one must spend in the Temple to incur the obligation of bringing a sacrifice if they became ritually impure while inside. They debate whether these requirements apply only to unwitting impurity or also to intentional cases, and whether similar requirements would apply to a nazir who unknowingly entered a cemetery.

The Mishna states that one who leaves the Temple by the shortest path after becoming impure will be exempt from bringing a sacrifice, while one who takes a longer path will be obligated. The Gemara then questions whether this distinction is measured in terms of time or physical distance.

Rabbi Oshaya offers a ruling regarding a leprous house: if one enters backward with only their nose remaining outside, they would not become impure, as the Torah imposes impurity only when entering a house in the typical manner. A braita supports this reasoning, noting that an impure person entering the Temple through the roof would not be liable for entering the Temple while impure, as entering through the roof is not the conventional method.

The Mishna clarifies that entering the Temple while impure is excluded from cases where the community would bring a bull offering for an erroneous court ruling. The bull offering applies only to sins requiring a fixed sin offering, not to those requiring a sliding scale offering. However, a bull sin offering would be brought for an erroneous court ruling involving nidda, specifically in a case where a man had relations with his wife and she became a nidda during the act. Abaye and Rava each quote different rabbis stating that in such a case, the man could incur an obligation of two sacrifices. Rava then attempts to understand the specific circumstances that would warrant this double punishment.
