Explanation: He left the Tum'ah, received Haza'ah twice, immersed and accepted Nezirus another time, and entered [the place of] Tum'ah again;

Implied question: What is the Chidush of the Beraisa?

Answer #1: Even though he did not return and say "I am a Nazir", rather, he said only "the Nezirus should take effect on me", he is a Nazir and he is lashed, like Rashi explained there. (Birkas Rosh - obviously, "Nezirus should take effect on me" is a proper acceptance. Here, he said "the Nezirus should take effect on me." The Chidush is that his initial acceptance is called Nezirus, even though it does not take effect until he accepts again.)

Answer #2: It teaches that once he becomes Tahor, it is incumbent on him to accept Nezirus immediately, and he transgresses Bal Te'acher if he does not [accept to be a] Nazir immediately.

Explanation: [There is no difference between a Nazir Tamei, i.e.] he vowed when he was Tamei, to a Nazir Tahor who became Tamei, except that a Nazir Tamei, his seventh day counts towards his count;

When he received Haza'ah day three, and again on day seven, and immersed, day seven counts towards his count of Nezirus Taharah;

This is because he need not bring a Korban on day eight for his Tum'ah. Immediately after he received Haza'ah twice, and immersed, it is proper for Nezirus to take effect on him immediately.

Implied question: He needs ha'Arev Shemesh (he is not totally Tahor until night). How can Nezirus takes effect on him [during the day]?

Answer: Tevul Yom (one who immersed from Tum'ah today) is a light Tum'ah. It does not prevent Nezirus from taking effect on him.

Explanation: [Day seven does not count] towards his count of Nezirus Taharah, for he must bring Chatas ha'Of, Olas ha'Of and an Asham on day eight...

And it says "v'Kidesh Rosho ba'Yom ha'Hu", that on that day he begins to count Nezirus Taharah. Below (18a) we establish this like Rebbi, that Nezirus Taharah does not takes effect on him until day eight.

Citation of Gemara: If you think that [Nezirus] does not takes effect on him, why do [the days] count for him towards his count?

Explanation: [This is difficult], because he did not accept Nezirus again.

Question: We should answer that he accepted Nezirus again, like we answered above, regarding one who left and entered!

Answer: If so, [the Beraisa] should have taught "this one (a Tamei who accepted Nezirus) must vow (accept Nezirus) again, and this one (a Nazir Tahor who became Tamei) need not vow again", since he comes to explain the differences between them.

Implied question: We could have asked that according to Reish Lakish, it should teach that this one drinks wine and becomes Tamei, and he is not lashed, and this one is lashed, like it asks below!

Answer: This is not difficult. We could have answered that this Tana does not discuss transgressions, only the law of one who became Tamei through Ones.

Implied question: According to R. Yochanan, why didn't it teach that this one brings a Korban for his Tum'ah, and this one does not bring a Korban?

Answer: This is what was taught, that day seven [of a Tahor Nazir who became Tamei] does not count towards his count, because he must bring a Korban!

Explanation: When he becomes Tahor, he need not vow again to be a Nazir, for the first Nezirus takes effect on him.

Support: Now it is fine that day seven counts towards his count, even if he did not accept again.

Assertion: Also, Reish Lakish agrees that he is lashed during his days of Tum'ah for drinking and shaving. They argue about lashes, i.e. only for Tum'ah, if they warned him about Tum'ah;

R. Yochanan holds that since Nezirus takes effect for other matters, i.e. for drinking wine and shaving, he is lashed also for Tum'ah, if they warned him to leave and he did not leave;

The Torah excluded him only from a Korban, below, but not from lashes for Tum'ah;

Reish Lakish holds that even though it takes effect for other matters, i.e. for wine and shaving, he is not lashed for Tum'ah;

Since the Torah excluded him from Korban Tum'ah, he is excluded from every law of Tum'ah, even from lashes.

Explanation: [He is lashed] for Tum'ah immediately, even within seven days, for he wants to be Metaher himself and fulfill Nezirus Taharah;

If he were not lashed, the Mishnah should have taught that he is not lashed!

Explanation: There it does not apply to teach that he is lashed for Tum'ah, for this is obvious, since it taught that he brings Korban Tum'ah!

Therefore, it did not teach above [in the Reisha,] that he is not lashed for Tum'ah.

Inference: [We infer that they are the same] because it did not teach "this one is lashed, and this one is not lashed" regarding Tum'ah.

Explanation #1: Some say that [in both cases] he is lashed for shaving.

Rebuttal: [If so], it should say "for shaving and wine, they are the same", since we discuss the Isur of shaving [and not the Mitzvah to shave and bring Korbanos]!

Explanation #2: It seems to me that "for shaving, they are the same" refers to the Mitzvah of shaving. He shaves on his seventh day of Taharah.

Implied question: Below (17b), this was a question, and it was resolved that a Nazir who was Tamei from the beginning does not shave on his seventh day of Taharah!

Answer: Even so, we were not particular to reject this answer like this (that it is unlike the conclusion below), for even without this Reish Lakish is refuted in the end.

Explanation: [We discuss] when he begins the count of his Nezirus when he became Tamei b'Shogeg;

We do not discuss ruin, when he intentionally ruins himself, i.e. he ruins his body with what is forbidden to him, for also Reish Lakish forbids him to be Metamei himself even within seven days;

If not, it should teach "this one may become Tamei, and this one is forbidden to become Tamei", for this is not ruin!

Explanation: This is just like one who vowed to be a Nazir while he is in a cemetery.

Citation of Gemara: If he shaved, drank wine or became Tamei, he receives 40 lashes.

Inference: This connotes even within seven days.

Question: We should answer that the case is, he left and entered [after he received Haza'ah] twice and he immersed, like we answered above on this very Beraisa!

Answer: It connotes to him that Tum'ah is like shaving and drinking wine. It takes effect on him during his days of Tum'ah, like we conclude that all agree that it takes effect;

Similar to this are lashes for Tum'ah. Even if he did not become Tahor [in between, Nezirus] takes effect on him during his days of Tum'ah. Therefore, [Reish Lakish] was refuted.

Distinction: However, in the first version [of the argument], Reish Lakish equated all of them, i.e. shaving and drinking wine to Tum'ah. Therefore, it was possible to answer above that he left and entered [for Reish Lakish holds that none take effect as long as he is Tamei].

Explanation: [We ask whether he must delay to be lashed,] just like we require a delay to be lashed for [a Tamei person] in the Mikdash, or not.

Explanation: [We suggested that they tell him not to accept Nezirus] while he is in a cemetery;

[We reject this, for if so] there is no need to delay. Obviously he is lashed without delaying!

Rhetorical question: Why doesn't a Tahor Nazir require a delay? We do not find at all that he requires a delay. This is because they warn him not to become Tamei, and he is a Nazir Tahor;

Also here, they warn him not to accept Nezirus, and he transgresses, he is lashed [immediately], just like when he was Tahor, and they warn him not to become Tamei.

Implied question: (Why is he lashed?) This is like a Lav she'Ein Bo Ma'aseh (there is no action), this that he accepts Nezirus!

Answer: It is a Lav with an action, this that he does not leave when he vows to be a Nazir. (Maharav Ransborg finds this difficult. He concludes like the Magid Mishneh, that one is lashed for a Lav that can be done through an action, even if he does it without an action.)

Explanation: He initially entered the Tamei place b'Heter. He is not lashed for entering;

However, when they warn him that he leave from the box, after [another] removed the top, he is unsure;

Perhaps no delay is required. Or, perhaps there is no difference. Wherever Tum'ah occurred, there we require a delay.

Explanation: This is only b'Ones (against the Nazir's will). If he consented, or if he himself uncovered, in such a case there is no question whether or not we require a delay;

In Shevuos (17a), it says regarding this question about a Tamei Nazir "or, perhaps regarding Ones, we have a tradition that to require a delay. There is no difference outside [the Mikdash] or inside.

Explanation: [We ask whether or not he must shave] the shaving of Tum'ah on the day that he becomes Tahor from Tum'ah;

Surely, he does not need a Korban, like our Mishnah taught. A verse below (18a) excludes this;

However, he is unsure about shaving, whether he must shave without a Korban Tum'ah, or not, for there is no shaving [for Tum'ah] without Korban Tum'ah.

Comment: However, surely he requires Tiglachas Taharah. When he counts [and finishes] Nezirus Taharah, he shaves and brings Korbanos Taharah, like the law of a Nazir Tahor.

Explanation: A verse below (18a) excludes [Korban Tum'ah]. We infer that he must shave, since it did not teach "and he does not shave on his seventh day."

Explanation: Since the Mishnah teaches that he does not bring [a Korban], automatically we know that he does not shave, for one depends on the other, for the verses are close to each other.

Implied question: Shaving is on day seven, and Korban Tum'ah is on day eight!

Answer: [The one who rejects the answer] understands that since he does not bring Korban Tum'ah, he does not shave.

Explanation: [They are the same] for Tiglachas Tum'ah, since he did not teach "this one shaves, and this one does not shave.

Explanation: Since he taught that day seven counts towards the count, i.e. because he does not bring a Korban, automatically we know that he does not shave, since he does not bring a Korban.

Explanation: [Days of Tum'ah do not count] when he became Tamei Mes. If he counted several days in Taharah, and became Tamei, he cancels even the initial count, like it says "veha'Yamim ha'Rishonim Yiplu";

All the more so, those days [of Tum'as Mes] do not count for him, like it says "v'Chiper Alav..."

Explanation: This is when he becomes Tahor. "V'Kidash Es Rosho ba'Yom ha'Hu" means that he begins the count of Nezirus Taharah.

Citation of Gemara: Days of Muchlat.

Explanation: These are when he dwells outside the Machaneh, and became Muchlat (there was a Siman Tum'ah in his Tzara'as). He counted part of the Nezirus that he accepted on himself before he became a Metzora;

Later, he healed, shaved from his Tzara'as. [We ask] what is the source that he returns to count to complete the Nezirus, [adding to] the number he counted before Tzara'as, and the days of Muchlat do not count for him towards his count of Nezirus?

However, days of Hesger surely count for him, since he need not shave like a Muchlat must. We do not compare him to days of Tum'ah, like a Muchlat.

Comment: [Yemei Chaluto] are the same as days of his Tum'ah (of Mes), which do not count for Nezirus. Likewise, his days of Muchlat do not count.

Explanation: [Days of his Tum'ah are Mevatel the earlier days,] like it says "veha'Yamim ha'Rishonim Yiplu."

Question: This itself we should learn from this [Mah Matzinu], that Yemei Chaluto are Mevatel the earlier days!

Answer: There is an exclusion below (44a), he is Soser due to Tum'ah (if he became Tamei), but he is not Soser due to shaving. Also, here, we can exclude and say "he is not Soser due to being Muchlat"!

Explanation: [One who accepted Nezirus in a cemetery, his hair is proper to be shaven,] and he resembles a Nazir. [Even so, these days] do not count towards his count;

Yemei Chaluto, in which his hair is not proper to be shaven, and in this way he does not resemble a Nazir, all the more so [these days] do not count towards his count!

Explanation: [Rather, the Beraisa discusses Tiglachas Taharah. The Kal va'Chomer] means as follows. A Nazir in a cemetery, his hair is proper to be shaven. The hair on him is destined to be shaven when he finishes Nezirus Taharah, for he does not shave on day seven. [Even so, these days] do not count;

In Yemei Chaluto, his hair is not proper to be shaven for Nezirus Taharah, for he needs to shave when he is healed from his Tzara'as. All the more so, [these days] do not count for him!
