(a)Our Mishnah (which prescribes a sixty-day period and a hundred and twenty-day period for a Nazir who is Tamei b'Safek and Muchlat b'Safek, is speaking about a short-term Nazir. The Beraisa permits someone who is a Nazir for a year (under the same circumstances) ...

1. ... to eat Kodshim - after two years (one year in case he was just a Tahor Nazir, and a second year in case he was a Tamei Nazir).

2. ... to drink wine and become Tamei Mes - after four years for his Nezirus d'Tum'ah (in case he was a Muchlat, in which case the first two shavings were for his Tzara'as), and the fourth for his Nezirus d'Taharah.

(b)In any event, he will need to shave four times - at the end of two years and seven days later (for his Safek Tzara'as), at the end of three years (for his Safek Nezirus d'Tum'ah) and at the end of four years (for his Nezirus d'Taharah).

(c)When he shaves the first time, he brings the two birds (for his Safek Tzara'as and the Chatas ha'Of (for his Safek Nezirus d'Tum'ah in case he was not a Muchlat) and the Olas Beheimah (in case he was a Nazir Tahor). The Tana does not mention the Olas ha'Of, because, Chazal did not obligate him to bring it on a Safek.

(d)Despite the fact that a Metzora Muchlat needs to shave after seven days, he cannot shave immediately after thirty days - in case he a Nazir Tahor and not a Metzora Muchlat, who is forbidden to shave until the termination of his Nezirus.

2)

(a)With his second shaving - he brings the Chatas ha'Of (for his Safek Tzara'as) and the Olas Beheimah (for his Safek Nezirus d'Tum'ah, in case he was not a Muchlat).

(b)When he shaves the third time, he brings the Chatas ha'Of (for his Nezirus d'Tum'ah, in case he was a Muchlat) and the Olas Beheimah (for his Nezirus d'Taharah, in case he was a Metzora but not Tamei). With his fourth shaving - he brings his Korban Taharah (a lamb for an Olah, a ewe for a Chatas, and a ram for a Shelamim, in case he had been both a Muchlat and Tamei).

3)

(a)We learned that when the Safek shaves the first time, he brings the two birds (for his Safek Tzara'as and the Chatas ha'Of (for his Safek Nezirus d'Tum'ah) and the Olas Beheimah (for his Safek Nezirus d'Taharah). The two birds are we referring to - are the birds brought by a Metzora Muchlat, one of which was Shechted and the other, sent away to the fields.

(b)The ...

1. ... the Chatas ha'Of (which is normally eaten by the Kohanim), has to be burned, seeing as he may be a Nazir Tahor, who does bring birds.

2. ... Olas ha'Of - is brought on condition that, should he be Tahor, it is a Nedavah.

(c)Even if he is not a Metzora Muchlat, there is no problem with his bringing the two birds - seeing as they are not brought into the Azarah, so there is no problem with 'Chulin ba'Azarah'.

(d)Whether he is a Muchlat or a Nazir Tamei, the Olas ha'Of is a Nedavah. Nevertheless, he needs to bring it - in case he is a Nazir Tahor, who has to bring one of his Korbanos in order to be able to shave.

4)

(a)A Metzora is also obligated to bring an Asham (without which he cannot eat Kodshim, which means that he must have brought his Asham, in order not to be a Mechusar Kipurim). The problem with bringing it is - that he will have to make a condition that, should he not be a Muchlat, it will be a Shelamim. Seeing as the latter can be eaten for two days and the former, only for one, this entails detracting from the days that one may eat a Shelamim (from two days to one, after which time it will have to be burned, and it is not permitted to create a situation whereby Kodshim may have to be burned).

(b)So we establish our Mishnah (which permits the Safek to eat Kodshim) like Rebbi Shimon - who permits making such a condition, because in his opinion, one may create a situation which whereby Kodshim may have to be burned.

5)

(a)'Tamei Safek u'Muchlat Vadai, Ochel b'Kodshim l'Achar Shemoneh Yamim' - meaning already from the eighth day.

(b)After shaving already on the first day, the procedure during the following week and on the eighth is - that he is sprinkled with the ashes of the Parah Adumah on the third and seventh days, and brings his Korbanos (Asham, Olah and Chatas) on the eighth.

(c)The basis for the radical difference between the case in our Mishnah and this case is - the fact that whereas Vadai Tzara'as overrides the prohibition of a Nazir to shave, Safek Tzara'as does not.

6)

(a)Seeing as he might be a Nazir Tahor however, it is not possible to shave immediately. Consequently, he performs his third shaving - on the thirty-first day from (and including) the eighth day (i.e. on the sixty-eighth day).

(b)He will be permitted to drink wine and become Tamei Mes - immediately after shaving.

(c)The order of precedence with regard to shaving, in the case of a Nazir who is Vadai Muchlat, Safek Tamei is - 1. Muchlat 2. Safek Tamei 3. Nazir Tahor.

7)

(a)'Muchlat Safek v'Tamei Vadai Ochel b'Kodshim l'Achar Sheloshim v'Shiv'ah Yamim'. He does not shave immediately in case he is not a Muchlat. So he brings his Korbanos for his Nezirus d'Tum'ah and shaves on the eighth day (after he has sprinkled on the third and the seventh days for his Nezirus d'Tum'ah).

(b)He will be permitted ...

1. ... to shave thirty days later (for his Safek Tzara'as), and to eat Kodshim on the following day (the thirty-eighth day).

2. ... to drink wine and become Tamei Mes - thirty-seven days later, seven days (incorporating the previous eighth day) when he shaves his third shaving (for the Nezirus d'Taharah to begin) and thirty days for his Nezirus d'Taharah (after seventy-four days).

(c)'Tamei Vadai u'Muchlat Vadai, Ochel b'Kodshim l'Achar Shemoneh Yamim' - because a Vadai Muchlat is able to shave his first shaving immediately, his second one on the seventh day, enabling him to bring his Korbanos on the eighth and to eat Kodshim then, too (and 'l'Achar Shemoneh Yamim really means 'on the eighth day', as we explained earlier).

(d)And he will be permitted to drink wine and to become Tamei Mes - on the forty-fifth day (after sprinkling on the following third and seventh days [for his Nezirus d'Tum'ah] and counting another thirty days [for his Nezirus d'Taharah]).

(a)When they asked Rebbi Shimon bar Yochai whether a Nazir Tahor and Metzora Muchlat (before he has counted seven days) can get away with one shaving, he answered in the negative - because the Nazir shaves in order to remove his growth, whereas the Metzora shaves in order to grow it.

(b)He also answered in the negative with regard to a Nazir Tahor and the second shaving of a Muchlat (li'Yemei Sefiro) despite the fact that the purpose of the latter too, is in order to remove the growth - because the shaving of the Metzora takes place (the day) before the sprinkling of the blood, whereas that of the Nazir takes place immediately afterwards.

(c)And the reason that he gave them as to why one shaving will not suffice for a Nazir Tamei who is also a Metzora (bi'Yemei Sefiro), in spite of the fact that both shavings are in order to remove the hair, is - because the former takes place after he has Toveled, whereas the latter takes place before.
