1) A NAZIR WHO BECOMES TAMEI THREE SEPARATE TIMES ON THE LAST DAY OF HIS PREVIOUS TUM'AH
QUESTION: The Gemara cites a Beraisa in which Rebbi Eliezer rules that when a Nazir becomes Tamei and thereby loses ("Soser") his Nezirus, and on the seventh day of his Tum'ah -- after he has completed the seven-day Taharah process -- he becomes Tamei again, and seven days later when he becomes Tahor from the second Tum'ah he becomes Tamei a third time, he brings only one Korban Tum'ah. However, if he becomes Tamei each of the three times on the eighth day, he brings three Korbenos Tum'ah.
TOSFOS asks, why does Rebbi Eliezer rule that the Nazir brings three Korbenos Tum'ah when he becomes Tamei on the eighth day? Rebbi Eliezer is the Tana in the Mishnah earlier (16b) who states that a Nazir does not lose any days of Nezirus and does not bring a Korban Tum'ah unless he has observed at least one day of Nezirus Taharah before he becomes Tamei. That is, he brings the Korban Tum'ah only if he becomes Tamei on the second day of his observance of Nezirus. If he becomes Tamei on the first day of his count, the Tum'ah does not "Soser" his Nezirus and he does not bring the Korban Tum'ah. Why, then, does Rebbi Eliezer in the Beraisa here rule that when a Nazir becomes Tamei on the eighth day three consecutive times, he brings three sets of Korbanos Tum'ah? If Rebbi Eliezer maintains that a Nazir does not start the count of Nezirus Taharah until the eighth day, the Nazir's Tum'ah on the eighth day occurs on the first day of his count! Since he was already "Soser" the previous Nezirus, the eighth day is always the first day of his count. Accordingly, he should not be required to bring a Korban Tum'ah for becoming Tamei on the eighth day. (Because of this question, the SHITAH MEKUBETZES and VILNA GA'ON (in Hagahos ha'Gra) assert that the Girsa of the Beraisa should read "Rebbi" instead of "Rebbi Eliezer." It is Rebbi who maintains that even if a Nazir becomes Tamei on the first day of his Nezirus, he is "Soser" the Nezirus and brings a Korban Tum'ah.)
Tosfos answers that Rebbi Eliezer follows the view of Rebbi Yosi b'Rebbi Yehudah, who maintains that the Nazir may begin his count of Nezirus Taharah on the seventh day and does not need to wait until the eighth day. On the seventh day he becomes Tahor and may begin the count of Nezirus Taharah; he does not need to wait until he brings the Korbanos on the eighth day in order to begin his count. The eighth day, therefore, is the second day of his count, and that is why he brings a Korban Tum'ah for becoming Tamei on the eighth day after the previous Tum'ah.
REBBI AKIVA EIGER (Teshuvos 1:214) asks a strong question on the answer of Tosfos. The Beraisa states that if the Nazir became Tamei three times, and the last two times he became Tamei on the seventh day of the previous Tum'ah, he brings only one Korban. Apparently, the intention of the Beraisa is to teach that although the Nazir became Tamei with three separate Tum'os, he does not need to bring three separate sets of Korbanos; the three periods of Tum'ah are considered like one long Tum'ah since he became Tamei before he was able to bring his Korban and start Nezirus Taharah. (This is how the SHITAH MEKUBETZES and VILNA GA'ON learn according to their Girsa of "Rebbi.")
According to Tosfos, who says that Rebbi Eliezer is the Tana of the Beraisa and maintains that the Nazir must have counted at least one day of Nezirus in order to be "Soser" his Nezirus, it is obvious that one brings only one Korban for the three sets of Tum'ah periods, because he never had the opportunity to count a day of Nezirus Taharah before he became Tamei again! When he became Tamei on the seventh day after the first Tum'ah, he did not yet count one day of Nezirus Taharah. Since he did not count a day of Nezirus Taharah he is not "Soser" his Nezirus and does not bring Korbenos Tum'ah! Similarly, when he became Tamei on the seventh day after the second period of Tum'ah, again he did not have a chance to count a day towards his Nezirus such that his Tum'ah could be "Soser" it and he should have to bring the Korbanos of a Nazir Tamei.
What is the Chidush of the Reisha according to Tosfos? The Reisha seems to be teaching that the three incidents of Tum'ah are considered one long Tum'ah and not as three distinct Tum'ah periods. Therefore, the Nazir brings only one Korban Tum'ah. According to Rebbi Eliezer, however, that is not the reason why the Nazir brings only one Korban Tum'ah. The reason he brings only one Korban Tum'ah is that he was not "Soser" one day of his Nezirus count!
