Jerusalem Talmud Nazir 3:3

משנה: מִי שֶׁאָמַר הֲרֵינִי נָזִיר נִיטְמָא יוֹם שְׁלֹשִׁים סָתַר אֶת הַכֹּל. רִבִּי אֱלִיעֶזֶר אוֹמֵר. אֵינוֹ סָתַר אֶלָּא שִׁבְעָה. הֲרֵינִי נָזִיר שְׁלֹשִׁים יוֹם נִיטְמָא יוֹם שְׁלֹשִׁים סָתַר אֶת הַכֹּל. MISHNAH: If somebody says, “I am a nazir” and became impure on the 30^th day³⁹Before he offered his sacrifices., he invalidated everything⁴⁰He has to wait 7 days to cleanse himself from the impurity of the dead, shave, bring the sacrifices prescribed for the impure nazir, and be a nazir another 30 days in purity.; Rebbi Eliezer says, he invalidated only seven⁴¹Since he could have brought the sacrifices on the 30th day, he has to wait 7 days to cleanse himself from the impurity of the dead, shave, bring the sacrifices prescribed for the impure nazir, wait another 7 days to have some hair to shave, and then brings his 3 sacrifices and shaves in purity.. “I am a nazir for 30 days,” if he became impure on the 30^th day, he invalidated everything⁴²R. Eliezer agrees that he has to start anew since he must wait until the 31^st day to bring his sacrifices..

HALAKHAH: “If somebody says, ‘I am a nazir’,” etc. Rebbi Abbahu in the name of Rebbi Joḥanan: Rebbi Eliezer learned from the sufferer from skin disease, for whom we find seven days between shaving and shaving⁴³Cf. Nazir 2:10:3" href="/Jerusalem_Talmud_Nazir.2.10.3">Chapter 2:10, Note 143.. Why does he not learn from the impure nazir? The sufferer from skin disease shaves repeatedly; the impure nazir does not shave repeatedly. The rabbis from Caesarea say, they disagree explicitly: Rebbi Joḥanan said, Rebbi Eliezer learned from the sufferer from skin disease; Rebbi Eleazar says, Rebbi Eliezer learned from the impure nazir⁴⁴Who shaves after 7 days, Numbers.6.9">Num. 6:9.. What difference does it make for Rebbi Eliezer whether the vow for nazir was implicit rather than explicit⁴⁵Whether he says “I am a nazir” and it is understood that he will be a nazir for 30 days, or he says “I am a nazir for 30 days”?? If the vow for nazir was implicit, he does not invalidate if he tears his hair out⁴⁶Numbers.6.5">Num. 6:5 spells out first a prohibition, “a shaving knife shall not touch his head”, followed by a positive commandment “he shall let the hair of his head grow wildly.” If the order had been inverted, it would have been clear that only shaving with a knife was forbidden. Now that the commandment of letting the hair grow is separated from the prohibition of using a knife, the majority opinion (Sifry Num. 25; Tosephta 4:3; Nazir 6:2:2-5" href="/Jerusalem_Talmud_Nazir.6.2.2-5">Halakhah 6:2, Nazir.39b">Babli 39b) holds that removing any hair is forbidden and the simultaneous removal of any two hairs during the period of nezirut invalidates the nezirut and requires a fresh start. Only on the 30^th day, tearing out a hair has no consequences since Numbers.6.5">Num. 6:5 also states: “until the days are completed he shall be holy,” and on the 30^th day of the implicit vow they are completed., and his seventh day⁴⁷If he became impure by the impurity of the dead, he has to shave on the 7th day itself. is counted for him; if the vow for nazir was explicit⁴⁸Then his days were not yet completed when he became impure., he invalidates if he tears his hair out and his seventh day is not counted for him.
