Nazir

Come and hear: The verse, And he defile his consecrated head  refers to a ritually clean [nazirite] who contracts ritual defilement; it enjoins on such a one to remove his hair and sacrifice birdofferings, but [by implication] exempts one, who vows to become a nazirite at a graveside, from removing his hair and sacrificing bird-offerings. For you might argue a fortiori: if the ritually clean [nazirite] who contracts ritual defilement must remove his hair and sacrifice bird-offerings, all the more must one who commenced [his naziriteship] whilst defiled remove his hair and sacrifice bird-offerings; therefore the text says expressly, 'And he defile his consecrated head', [implying] that only the ritually clean [nazirite] who contracts ritual defilement is required by Scripture to remove his hair and sacrifice bird-offerings, but not the person who vowed to become a nazirite at a graveside. This proves then [that the latter is exempt]. Who is the author of the following dictum, taught by the Rabbis, [viz.,] The only difference between a ritually defiled person who makes a nazirite vow, and a ritually clean nazirite who contracts ritual defilement, is that the former reckons his seventh day [of purification] as part of his period [of naziriteship],  whilst the latter does not reckon his seventh day as part of his [new] period? — R. Hisda said: It is Rabbi, for Rabbi has said that the naziriteship [after defilement] does not recommence until the eighth day of purification, for if you were to say it is R. Jose son of R. Judah, surely he holds that the naziriteship [after defilement] begins to operate on the seventh day of purification. Where are these opinions of Rabbi and R. Jose son of R. Judah [to be found]? — It has been taught: And he shall hallow his head that same day;  Rabbi says [that this refers to] the day on which he offers his sacrifices,  but R. Jose son of R. Judah says [it refers] to the day on which he polls. And who is the author of the teaching that, 'A nazirite who contracts ritual defilement many times brings a single sacrifice only'?  — R. Hisda said: It is R. Jose son of R. Judah, who has said that the naziriteship [after defilement] recommences on the seventh day of purification. Thus the case [contemplated] could arise if he were to contract defilement on the seventh day [of purification]  and then again on the seventh day after that,  nevertheless since there was no period when he could have brought his sacrifice,  he need offer one sacrifice only [for both defilements]. According to Rabbi, however, if he contracted ritual defilement on the seventh day and then again on the seventh day,  the whole is one long period of ritual defilement,  whilst if we suppose he contracts ritual defilement upon the eighth day and again upon the eighth day, then there is a point of time [on each occasion] when he could bring his sacrifice. What is Rabbi's reason [for his opinion]? — The verse says [first], And make atonement for him that he sinned by reason of the dead,  and then, And he shall hallow his head.  And what does R. Jose son of R. Judah [say to this]? — If this is its intention, the text should read simply, 'And he shall hallow his head'.
