Answer: The case is, he left and returned (after becoming Tahor and accepting Nezirus).

Question (Beraisa): The only difference between a Tamei who accepted Nezirus and a Tahor Nazir who became Tamei, is that the former counts the seventh day of becoming Tahor towards the term of Nezirus, but the latter does not.

If the Nezirus does not take effect (unless he accepts Nezirus again), why does day seven count?

Correction (Mar bar Rav Ashi): All agree that it takes effect. They argue about lashes;

R. Yochanan holds that since it takes effect, he is lashed (if he transgresses).

Reish Lakish holds that even though it takes effect, he is not lashed.

Question (R. Yochanan - Mishnah): If Reuven accepted Nezirus in a cemetery, even if he stayed there 30 days, they do not count. He does not bring Korbanos Nazir Tamei;

Inference: he does not bring the Korbanos, but he is lashed!

Answer: Really, the Mishnah should say that he is not lashed. Since the Seifa says 'if he left (and became Tahor) and returned to the cemetery, the days are counted, and he brings Korbanos Nazir Tamei", the Reisha said that he does not bring Korbanos Nazir.

Question (Beraisa): The only difference between a Tamei who accepted Nezirus and a Tahor Nazir who became Tamei, is that the former counts the seventh day of becoming Tahor towards the term of Nezirus, but the latter does not.

Inference: There is no difference regarding lashes!

Answer: No, they are the same regarding shaving (when they finish Nezirus and bring Korbanos).

Objection: If the latter is lashed, but not the former, the Beraisa should teach this!

Answer: The Beraisa teaches only matters of fixing the Nazir, not transgressions.

Question (Beraisa): If a Tamei accepted Nezirus, he may not shave, drink wine, or become Tamei. If he did any of these, he receives 40 lashes.

This refutes Reish Lakish.

Question (Rava): If one accepted Nezirus while in a cemetery, must he delay there (the time needed to bow) to be lashed?

Question: What is the case?

Suggestion: He was warned not to accept Nezirus.

Rejection: If so, he is lashed even if he does not delay, just like a Tahor Nazir who was warned not to become Tamei is lashed, even without delay!

Answer: Rather, he entered the cemetery in a chest (that shields from Tum'ah). Someone else removed the bottom, making him (tower over a grave and become) Tamei.

There is a tradition (from Sinai) that a Tamei in the Beis ha'Mikdash is lashed only if he delays. Does the tradition apply only inside the Mikdash, or even outside?

This question is unresolved.

Question (Rav Ashi): If one accepted Nezirus while in a cemetery, does he need to shave (immediately when he becomes Tahor)?

Perhaps only a Tahor Nazir who became Tamei needs to shave.

Or, perhaps there is no distinction!

Answer #1 (Mishnah): If Reuven accepted Nezirus in a cemetery, even if he stayed there 30 days, they do not count. He does not bring Korbanos Nazir Tamei.

Inference: He need not bring the Korbanos, but he must shave.

Rejection: No, the Mishnah means that he does not bring the Korbanos because he does not shave.

Answer #2 (Beraisa): The only difference between a Tamei who accepted Nezirus and a Tahor Nazir who became Tamei, is that the former counts the seventh day of becoming Tahor towards the term of Nezirus, but the latter does not.

Suggestion: They are the same regarding shaving (i.e. both shave)!

Rejection: No, they are the same regarding lashes.

Question: If they are different regarding shaving, the Beraisa should teach this!

Answer: This follows from what was taught, that that the seventh day counts for the former and not for the latter.

Answer #3 (Beraisa) Question: It is clear that days of Tum'ah (Tum'as Mes) do not count towards Nezirus. What is the source that also days when he is a Metzora Muchlat do not count?

Answer #1: A Metzora Muchlat shaves and brings a Korban, just like a Tamei Nazir. Likewise, just like days of a Tamei Nazir do not count, also days of a Metzora Muchlat do not count!

Rejection: We cannot learn thusly.

Days of a Tamei Nazir do not count, because he nullifies the previous count. A Metzora Muchlat does not nullify the previous count. (Perhaps) his days count!

Answer #2: We learn from a Kal v'Chomer.

If one accepted Nezirus in a cemetery, his hair is destined to be shaved, yet the days of Tum'ah do not count. The hair of a Metzora Muchlat is not destined to be shaved, all the more so his days do not count!

Suggestion: The former is destined to shave like a Tamei Nazir.

Rejection: No, he will shave like a Tahor Nazir (after fulfilling the count).
