Rabban Shimon ben Gamliel says: [If] he brought [the] three animals and did not specify —- the one fit for the sin-offering is offered as a sin-offering, [the one fit] for the burnt-offering is offered as a burnt-offering, [and the one fit] for the peace-offering is offered as a peace-offering.  He would take the hair from his head of nezirus and cast it under the pot. If he shaved [his head] in the provinces, he would cast it under the pot. In regard to what was this said? In regard to the head-shaving in taharah. But for the head-shaving in tumah, he did not cast [his hair] under the pot. R’ Meir says: All [nezirim] cast [their hair] under the pot except for one who was tamei [who shaved] in the provinces.
