A Paschal lamb offered in a state of purity defers those who are unable to bring the offering to the second Pesaḥ, but a Paschal lamb brought in a state of impurity does not defer those who are unable to bring the offering to the second Pesaḥ. And this Master, Rav Adda bar Ahava, who said there is redress, holds that even a Paschal lamb offered in a state of ritual impurity defers those who are unable to bring the offering to the second Pesaḥ.

It was stated that the Sages discussed the following matter: If one-third of the members of the community were zavim, and one-third of them were ritually pure, and one-third of them were ritually impure with impurity imparted by a corpse, what is the halakha? Rabbi Manni bar Pattish said: Those who were ritually impure with impurity imparted by a corpse do not perform the ritual of the Paschal lamb on the first Pesaḥ or the second Pesaḥ.

On the first Pesaḥ, they do not perform the ritual of the Paschal lamb because the zavim increased the number of the ritually pure, as zavim may not perform the ritual of the Paschal lamb in a state of impurity. Therefore, the ritually impure with impurity imparted by a corpse are the minority, and a minority may not perform the ritual of the Paschal lamb in a state of ritual impurity on the first Pesaḥ. On the second Pesaḥ, they may not perform the ritual of the Paschal lamb for a different reason: The zavim are joined with those who were ritually impure with impurity imparted by a corpse, who did not perform the ritual of the Paschal lamb on the first Pesaḥ. Consequently, they are the majority, and the offering of the majority is not deferred to the second Pesaḥ.

MISHNA: In a case of a Paschal lamb whose blood was sprinkled and subsequently it became known that the meat or blood was ritually impure, the frontplate of the High Priest appeases God for the ritual impurity after the fact, and the owners are exempt from observing the second Pesaḥ. If it became known later that the body of the individual who brought the Paschal lamb had become ritually impure, the frontplate does not appease God. The individual has not fulfilled his obligation to bring the Paschal lamb, and therefore he must observe the second Pesaḥ. This is because the Sages said that with regard to the nazirite and one who performs the ritual of the Paschal lamb, the frontplate appeases God for both impurity of the blood and meat of the offering, but the frontplate does not appease God for impurity of the body of the individual bringing the offering.

The mishna introduces a halakha with regard to ritual impurity of the deep, a term that refers to a source of impurity that is unknown to anyone and is discovered only after it has rendered someone impure. If it became known after the offering was brought that the person had become impure due to ritual impurity of the deep, e.g., if he was informed that there was a concealed grave under the place he had sat in a house where he had previously stayed, the frontplate appeases God and the offering is valid.

GEMARA: The Gemara begins with an inference with regard to a Paschal lamb that is found to be ritually impure after its blood was sprinkled. The reason the frontplate appeases God is that the blood was sprinkled and it subsequently became known that it was ritually impure. However, if it became known that it was ritually impure and its blood was subsequently sprinkled, the frontplate does not appease God and the offering is disqualified.

The Gemara raises a contradiction from what was taught in a baraita: For what does the frontplate appease God? It appeases God for the blood and the meat and the fat that became impure, whether unwittingly or intentionally, whether by circumstances beyond his control or willfully, and whether the offering belonged to an individual or the public. This indicates that the frontplate appeases God even when the blood was sprinkled, despite the fact that it was already known that the meat or blood was ritually impure.

Ravina said that the baraita should be understood as follows: With regard to its ritual impurity, regardless of whether it became impure unwittingly or intentionally, the frontplate appeases God for the impurity and the offering is accepted. However, with regard to the sprinkling of its blood, if it was unwittingly sprinkled while the meat was ritually impure, then the offering is accepted, but if it was intentionally sprinkled while the meat was impure, it is not accepted.

Rabbi Sheila said that the baraita should be understood as follows: With regard to sprinkling the blood of the impure offering, whether it was done unwittingly or intentionally, it is accepted. However, with regard to the manner in which it contracted its ritual impurity, if it became impure unwittingly the offering is accepted, and if it became impure intentionally it is not accepted.

The Gemara explains: However, that which was taught in the baraita that the frontplate appeases God regardless of whether the impure offering was brought unwittingly or intentionally, this is what it is saying: If the offering became impure unwittingly and one sprinkled its blood, whether unwittingly or intentionally, it is accepted.

And from that which was taught in this mishna with regard to blood that was sprinkled and subsequently it became known that the offering was impure, one should not infer that the reason the frontplate appeases God is specifically that the blood was sprinkled and subsequently it became known that the offering was impure, but if it became known that the offering was impure and subsequently the blood was sprinkled, even unwittingly, the frontplate does not appease God. In fact, the same is true, i.e., the frontplate appeases God, even if the impure status of the offering became known and the blood was subsequently sprinkled.

And that which was taught in the mishna with regard to blood that was sprinkled and subsequently it became known that it was impure, was formulated in that particular way because the tanna wanted to teach the latter clause of the mishna, which states that if the body of the individual bringing the Paschal lamb became impure, the frontplate does not appease God for his impurity. In this case, even if the blood was sprinkled and subsequently it became known that the body of the individual had been impure, the frontplate does not appease God. Therefore, he also taught the first clause in a parallel way, as one in which the blood was sprinkled and subsequently it became known that the offering was impure. However, the halakha holds true even if the ritual impurity of the blood or meat of the offering was known before the sprinkling of the blood.

It was taught in the mishna that if one became ritually impure through impurity of the deep, the frontplate appeases God. Rami bar Ḥama raised a dilemma: With regard to the priest who facilitates acceptance of their offerings, i.e., who performs the service of the Paschal lamb or the offerings of the nazirite, is ritual impurity of the deep permitted for him too or not? Do we say that they learned the leniency of impurity of the deep through oral tradition only with regard to the owners of the offering, but they did not learn through oral tradition that it applies also to a priest? Or perhaps they learned through oral tradition that this leniency applies to the sacrifice of the Paschal lamb and the offering of a nazirite, and therefore it is no different whether the priest was impure or whether the owners were impure.

Rava said: Come and hear a resolution to this question, as Rabbi Ḥiyya taught that they stated the rule of impurity of the deep only with regard to ritual impurity imparted by a corpse. The Gemara infers: Ritual impurity imparted by a corpse was specified to exclude what? Is it not to exclude impurity of the deep of a creeping animal, so that in a case of impurity caused by a creeping animal that had not been known, the frontplate does not appease God?

And with what are we dealing? If we say that we are dealing with a case where the owners became impure, to whom does this apply? If it applies to a nazirite, is impurity imparted by a creeping animal effective in interrupting his term as a nazirite and requiring him to bring offerings? The Merciful One states: “And if any man shall die very suddenly beside him and contaminate his nazirite head, he shall shave his head on the day of his purification; on the seventh day shall he shave it” (Numbers 6:9). This indicates that one’s term as a nazirite is interrupted only due to ritual impurity imparted by a corpse and not due to the impurity imparted by a creeping animal.

Rather, say that we are dealing with one performing the ritual of the Paschal lamb. If so, it works out well according to the one who said one may not slaughter the Paschal lamb and sprinkle its blood for those who are impure from creeping animals, and therefore there is reason to discuss impurity of the deep. However, according to the one who said that one may slaughter and sprinkle the blood of the Paschal lamb for those who are impure from creeping animals so that they will be able to eat its meat at night, when they are pure, now you have said that known impurity is permitted for him, meaning that even when it is clear that one is ritually impure from a creeping animal, he is not prevented from participating in the Paschal lamb. In that case, with regard to impurity of the deep, is it not all the more so true that he is permitted to offer the Paschal lamb?

Rather, is Rabbi Ḥiyya not referring to a priest who has become ritually impure? Learn from here that impurity of the deep is permitted for a priest.

Rav Yosef said: No, this cannot be proven from Rabbi Ḥiyya’s statement. Actually, it is possible to say that Rabbi Ḥiyya was referring to a case where the owners became ritually impure with impurity of the deep, and they intended to offer the Paschal lamb. And the limitation of the leniency to a case of ritual impurity imparted by a corpse is meant to exclude impurity of the deep imparted by the discharge of a zava. The frontplate does not appease God with regard to ritual impurity from impure discharges that are unknown.

The Gemara asks: Does the frontplate not appease God with regard to ritual impurity of the deep imparted by the discharge of a zava? Wasn’t it taught in a baraita that Rabbi Yosei says: A woman who keeps watch a day for a day is a woman who discharges blood for one or two days at a time when she does not expect her menstrual period. The case under discussion is one where she experienced a discharge for one day and they slaughtered a Paschal lamb and sprinkled the blood for her
