The Mishnah then says that if he becomes Tamei on day 101 (the day on which
he is supposed to bring his Korbanos), according to the Chachamim he loses
30 days, and according to Rebbi Eliezer he loses nothing; he merely waits
seven days until he becomes Tahor and then he brings his Korbanos (see Chart
#1). The Gemara discusses the reasoning for the opinions of Rebbi Eliezer
and the Chachamim earlier (6a) and discusses it only briefly here. We will
review and clarify the main points of the Sugya, based on the following
questions that we must ask on the Mishnah:
Why is it that if a Nazir becomes Tamei on day 30 he loses the entire
Nezirus, according to the Chachamim who argue with Rebbi Eliezer? The
Halachah is that "Miktzas ha'Yom k'Kulo," and therefore the beginning of day
30 is already the completion of the Nezirus! The end of day 30 is *after*
the Nezirus and he is already able to bring his Korbanos! Why, then, should
he lose the entire 30 days? This question is asked according to the view of
Rav Masna, who says that Nezirus is 30 days and "Miktzas ha'Yom" is
"k'Kulo."
The same question may be asked according to Bar Pada, who argues with Rav
Masna and says that "Miktzas ha'Yom" is *not* "k'Kulo," and that Nezirus is
only 29 days. If Stam Nezirus is only 29 days, then if he becomes Tamei on
day 30, it is *after* his Nezirus and he should not lose the Nezirus!
This question certainly applies to what the Mishnah says in the last case --
if a person accepts a 100-day Nezirus and becomes Tamei on day 101, the
Chachamim say that he loses 30 days of his Nezirus. Why should he lose
anything at all? He only accepted a 100-day Nezirus, which he observed in
full! He is merely waiting to bring his Korbanos on day 101, and when he
becomes Tamei at that point, he is not becoming Tamei during the observance
of his Nezirus and he should not lose any days of his Nezirus! In fact, the
Rishonim point out that if he becomes Tamei on day 102 (before bringing his
Korbanos), everyone agrees that he does not lose any days, because his
Nezirus is completed. Why, then, when he becomes Tamei on day 101, should he
lose anything, and if for some reason the Tum'ah is "Soser" his Nezirus, why
should he lose 30 days?
(a) TOSFOS and the ROSH explain that the reason a Nazir loses his Nezirus
according to the Chachamim if he becomes Tamei on day 30 of a Stam Nezirus
differs according to Rav Masna and according to Bar Pada. According to Rav
Masna, who says that Stam Nezirus is 30 days, the reason he loses his
Nezirus is because he has not yet finished his Nezirus when he becomes
Tamei. Why, though, has he not finished his Nezirus, if Rav Masna holds that
"Miktzas ha'Yom k'Kulo" and thus the Nezirus should be over at the very
beginning of day 30? They answer that "Miktzas ha'Yom k'Kulo" is said only
when the Nazir actually ends his Nezirus on that day by bringing his
Korbanos of Nezirus Taharah. If he does an action to end his Nezirus, then
he is able to make "Miktzas ha'Yom k'Kulo" take effect. But "Miktzas ha'Yom
k'Kulo" does not work automatically if he does nothing to end the Nezirus.
In the case of the Mishnah, he did nothing to end the Nezirus. Rather, he
became Tamei before the end of the day, and therefore he is not able to
bring his Korbanos of Nezirus Taharah. Since he did not actively end the
Nezirus, we do not apply "Miktzas ha'Yom k'Kulo," and it is as if he became
Tamei in the middle of his Nezirus. Therefore, the Chachamim maintain that
he loses the entire Nezirus. Rebbi Eliezer, who says that he does not lose
the Nezirus, holds, like we mentioned in the question, that "Miktzas ha'Yom
k'Kulo" applies even if the Nazir did nothing to end the Nezirus. This is
according to Rav Masna who says that Stam Nezirus is 30 days.
According to Bar Pada, who says that Stam Nezirus is 29 days, the Gemara
concludes that the reason he is loses 30 days is a Gezeirah d'Rabanan, as
the Gemara says earlier (5b). This Gezeirah, that the Nazir loses all of his
Nezirus if he becomes Tamei on day 30, was made because of a case where the
Nazir explicitly accepted upon himself to observe Nezirus for 30 days (in
which case he must observe 30 *complete* days). People are accustomed to
observing Nezirus for 30 days since they cannot bring the Korbanos until day
30, and thus they think that Stam Nezirus is 30 days; when one says that he
will observe Nezirus for 30 days, then, according to Bar Pada, he must
observe 30 complete days of Nezirus and bring the Korbanos on day 31 (since
Bar Pada does not hold of "Miktzas ha'Yom k'Kulo"). The Rabanan therefore
decreed that in every case of a Stam Nezirus, the Nazir should bring the
Korbanos on day 31 and count day 30 as part of his Nezirus because people
confuse it with a Nazir who accepted explicitly to observe 30 days of
Nezirus.
This explains why the Chachamim say that he loses the entire Nezirus when he
becomes Tamei on day 30 of a Stam Nezirus. What about the case where he
becomes Tamei on day 101 of a 100-day Nezirus? Tosfos explains that
according to both Rav Masna and Bar Pada, becoming Tamei on day 101 is a
Gezeirah d'Rabanan. The Rabanan decreed that if he becomes Tamei on day 101
of a 100-day Nezirus, the Nazir should lose 30 days because it might be
confused with day 30 of a Stam Nezirus, in which case -- if he becomes Tamei
on day 30 -- he loses 30 days. According to Rav Masna, the Nazir who becomes
Tamei on day 30 loses his 30 days mid'Oraisa, and thus it is fitting to make
a Gezeirah for one who becomes Tamei on day 101. According to Bar Pada, who
holds that losing days of Nezirus when one becomes Tamei on day 30 is only
mid'Rabanan, it must be that it is all one Gezeirah -- that when a Nazir
becomes Tamei on day 30 or on day 101, he loses 30 days, and we do not view
it as a Gezeirah l'Gezeirah.
What, though, does day 101 have to do with day 30 that the Rabanan should
need to make a Gezeirah on one because of the other? Why will people confuse
the two days?
The answer, according to Bar Pada, is simple. Both days (101 and 30) are the
days following a full Nezirus period; they are the days on which a Korban is
brought. According to Bar Pada, day 29 of a Stam Nezirus is really the last
day, and day 30 is the day that follows it. Similarly, day 101 (of a 100-day
Nezirus) is the day that follows day 100 upon which the Korbanos may be
brought. The Gezeirah d'Rabanan says that whenever a Nazir becomes Tamei on
a day on which the Korbanos could be brought, he loses 30 days. People will
therefore remember to be Soser 30 days if they became Tamei on day 30 of a
Stam Nezirus, whether or not the person accepted upon himself explicitly to
observe 30 days, or just to observe a Stam Nezirus.
According to Rav Masna, the reason he loses 30 days if he becomes Tamei on
day 30 is because we do not say "Miktzas ha'Yom k'Kulo" and it is considered
the middle of the Nezirus. How is that going to be confused with day 101 of
a 100-day Nezirus, which is entirely *after* the Nezirus is finished? On day
100, the Nezirus is finished, and day 101 is only the day for bringing the
Korbanos! What does day 101 have in common with day 30, which *is* part of
the actual Nezirus (since a Stam Nezirus is 30 days). How will day 30 be
confused with day 101 according to Rav Masna?
The answer is that people do not realize that "Miktzas ha'Yom k'Kulo" does
not apply when the Nazir becomes Tamei before bringing his Korbanos. People
think that "Miktzas ha'Yom k'Kulo" applies automatically, like Rebbi Eliezer
holds. Therefore, they think that day 30 is observed as Nezirus simply
because the Nazir has not yet brought his Korbanos. They compare it to day
101 of a 100-day Nezirus. That is why the Rabanan made a Gezeirah that the
Nazir loses 30 days when he becomes Tamei on day 101, so that it should not
get confused with day 30, according to Rav Masna.
(b) The RAMBAM (Perush ha'Mishnayos) takes an entirely different approach to
this Mishnah. The Rambam explains that if a Nazir becomes Tamei on day 30,
then according to the way that Rav Masna learns, "Miktzas ha'Yom" is
"k'Kulo" according to *everyone*; both Rebbi Eliezer and the Chachamim agree
that "Miktzas ha'Yom" is "k'Kulo" and that once the day has begun, his
Nezirus is completed. Why, then, do the Chachamim say that he loses 30 days
if he becomes Tamei? The Rambam answers that it is because the Chachamim
hold that whenever a Nazir becomes Tamei on the day on which he brings his
Korbanos, he loses 30 days. The Rambam appears to learn that this is a
Halachah mid'Oraisa, that if a Nazir becomes Tamei on the day that he is
supposed to bring his Korbanos because he has just completed his Nezirus, he
loses 30 days (according to the Chachamim). Rebbi Eliezer says that he is
not Soser any of the Nezirus, but he simply counts seven days until he
becomes Tahor.
The Rambam says that the Chachamim are simply following their own view in
the case of a Nazir who became Tamei on day 101. Day 101 of a 100-day
Nezirus is -- like day 30 of a Stam Nezirus -- the day that a Nazir is
supposed to bring his Korbanos. Therefore, the Chachamim hold that he loses
30 days, because they hold that a Nazir who becomes Tamei on the day that he
is supposed to bring his Korbanos loses the entire Nezirus. Rebbi Eliezer,
too, is following his own view and holds that he does not lose any of the
Nezirus.
This explanation fits very well with the words of the Gemara in our Sugya
(top of 16b), where the Gemara explains that Rebbi Eliezer's reasoning (for
his view that if one becomes Tamei on day 30 he only needs to wait seven
days) is because Rebbi Eliezer holds that becoming Tamei on the day of
"Achar Melos" is only Soser seven days. According to the way Tosfos learns,
the Gemara is skirting the main issue. The point about which Rebbi Eliezer
and the Chachamim argue in the case of a Nazir who becomes Tamei on day 30,
according to Rav Masna, is not whether "Achar Melos" is Soser seven days;
*everyone* agrees that after the Nezirus is over, he loses only seven days!
The question, rather, is whether this day, day 30, is considered "Achar
Melos" because we apply "Miktzas ha'Yom k'Kulo" on day 30, or is it "Toch
Melos" (still during the Nezirus), because we do not apply "Miktzas ha'Yom
k'Kulo" when he becomes Tamei.
According to the Rambam, though, the Gemara is clear. The Gemara says that
according to Rebbi Eliezer "Achar Melos" is Soser seven days, implying that
according to the Chachamim, "Achar Melos" is always Soser *30* days.
However, the Rambam's explanation does not fit into the Gemara earlier
(beginning of 6b) which brings a proof from our Mishnah to Rav Masna's view.
It seems that the Rambam must have had a different Girsa in that Gemara
which fit with his explanation of the Mishnah here.
According to the Rambam, what is the Chachamim's source that on the day of
bringing Korbanos, the Nazir is Soser 30 days? The answer is that
apparently, the Chachamim agree with Rebbi Eliezer's Derashah of "Ten Lo
Toras Melos" that the Gemara mentions (6b), which teaches that if a Nazir
becomes Tamei on "Yom Melos" (the last day of his Nezirus), he is Soser 30
days. Apparently, according to the Rambam, the Chachamim agree with this
Derashah. However, instead of saying that it applies to a Nazir who becomes
Tamei on "Yom Melos," on the last day of his Nezirus, they only apply this
Derashah to a Nazir who becomes Tamei "Achar Melos," on the day of bringing
Korbanos for his Nezirus -- that is when the Torah says that he is Soser his
Nezirus for 30 days.
