Halakhah sur Middot 2:10

From the laws of the commandment - that which they, may their memory be blessed, said (Mishnah Middot 2:5), "Where does he shave his hair? In the women's courtyard," and the chamber of nazirites was there in the southeast corner, and they would cook their peace-offerings there and throw the hair into the fire, and if he shaved in the [rest of the] country, he would have discharged [his obligation] (Mishneh Torah, Laws of Nazariteship 8:3); [that] in any place that he shaves, he throws it under the cauldron; [that] he does not shave until the opening of the courtyard be open, as it is stated (Numbers 6:18), "at the opening of the Tent of Meeting," and the understanding of the verse is not that he should shave in front of the opening, as there would be a disgrace to the Temple in this; so [too,] that which they, may their memory be blessed, said about this commandment (Nazir 46a), [that] a nazirite who pulled out [his hair] does not need to pass a blade over [his head] even though he does not have hair, and so [too,] if he does not have palms [of the hand], behold, this one brings his sacrifices, and afterwards he can drink and become impure, and even if he has hair, once he has brought his sacrifices, even though he did not shave, the shaving does not impede [it], and he can drink and become impure in the evening, even though he did not give it on his palms and wave it, as all of these things are for [the fulfillment of] the commandment and not for an impediment; [that] even though the shaving does not impede, it is a commandment to shave even after much time; [that] a nazirite who shaved without a blade or shaved with a blade but left [at least] two hairs, did not do anything and did not fulfill the commandment of shaving, whether [in the case of] a pure nazirite, or whether [in the case of] an impure nazirite; that if he shaved upon his peace-offerings and they were found to be disqualified, his shaving is disqualified, [but] if he shaved upon [all] three animals that he is sacrificing, and it comes out that [at least] one of them is fit, his shaving is fit, and he shall bring the rest of his offerings [afterwards] and they are to be sacrificed, as per their law, [and] these three animals are a male lamb for a burnt-offering, a female lamb for a sin-offering and a ram for a peace-offering, and he brings six and two-thirds issaron of fine flour with the ram, and he bakes twenty loaves from it; and the rest of its details - are in Tractate Nazir.
