Standard nezirus is for thirty days. [If] he shaved [his head], or [if] bandits shaved it, he forfeits thirty days.  A nazir who shaved, whether with a scissors or with a razor or by plucking a minute amount, is liable.  A nazir may rub or scratch [his head], but he may not comb it. R’ Yishmael says: He may not rub it with earth since it causes the hair to fall out.

A nazir who drank wine all day is liable to only one [set of lashes]. [If] they said to him: “don’t drink,” “don’t drink,” and he drank —- he is liable for each one.  [If] he shaved [his head] all day, he is liable to only one [set of lashes]. [If] they said to him: “don’t shave,” “don’t shave,” and he shaved —- he is liable for each one.  [If] he contaminated himself with the tumah of the dead all day, he is liable to only one [set of lashes]. [If] they said to him: “don’t contaminate yourself,” “don’t contaminate yourself,” and he contaminated himself —- he is liable for each one.

Three matters are forbidden to a nazir: tumah, head-shaving, and products of the grapevine. There is an [aspect of greater] stringency to tumah and head-shaving than to products of the grapevine, in that tumah and head-shaving [cause] forfeiture, whereas the products of the grapevine do not cause forfeiture. There is an [aspect of greater] stringency to products of the grapevine than to tumah and head-shaving, in that there are no exceptions to the prohibition of the products of the grapevine whereas there are exceptions to the prohibitions of tumah and head-shaving —- where shaving is an obligation, and where there is an abandoned corpse. And there is an [aspect of greater] stringency to tumah than to head-shaving in that tumah causes forfeiture of all [the days previously observed] and one is obligated because of it [to bring] a sacrifice, whereas head-shaving causes forfeiture of only thirty days, and one is not obligated because of it to bring a sacrifice.

6. What is the procedure for head-shaving in tumah? He would [be] sprinkled on the third and on the seventh [days], shave [his head] on the seventh, and bring his sacrifices on the eighth. However, if he shaved on the eighth, he brings his sacrifices on that same day; [these are] the words of R’ Akiva. R’ Tarfon said to him: What is [the difference] between this one and a metzora? He said to him: This one’s purification is dependent on his days, while a metzora’s purification depends on his shaving, and he cannot bring a sacrifice unless the sun has set on him.

What is the procedure for head-shaving in taharah? He would bring three animals —- a sin-offering, a burnt-offering, and a peace-offering —- slaughter the peace-offering and shave upon it; [these are] the words of R’ Yehudah. R’ Elazar says: He did not shave [his head] except on [the slaughter of] the sin-offering, because the sin-offering takes precedence on every occasion. However, if he shaved [his head] on any of the three, he has discharged his obligation.

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.

He cooked the peace-offering or overcooked it. The Kohen [then] takes the cooked foreleg of the ram, and one unleavened loaf from the basket, and one unleavened wafer, and places [them] on the palms of the nazir and waves them. After this the nazir becomes permitted to drink wine and to become tamei by the dead. R’ Shimon says: Once one of the bloods was thrown for him, the nazir becomes permitted to drink wine and to become tamei from the dead.

[If] he shaved [his head] following the sacrifice and it was found [to be] invalid —- his shaving is invalid and his sacrifices do not count for him.  [If] he shaved after a sin-offering [which was slaughtered] not for its designated purpose, and then he brought his offerings for their designated purpose —- his shaving is invalid and his sacrifices do not count for him. [If] he shaved after the burnt-offering or after the peace-offering [which were slaughtered] not for their designated purpose, and then he brought his offerings for their designated purpose —- his shaving is invalid and his sacrifices do not count for him. R’ Shimon says: That sacrifice does not count for him, but the other sacrifices do count for him. If he shaved after [all] three and one of them was found to be valid —- his shaving is valid and he brings the other sacrifices.

Someone for whom one of the bloods had been thrown, and he then became tamei —- R’ Eliezer says: He forfeits all. But the Sages say: He should bring the rest of his offerings and become tahor. They said to him: It happened with Miriam the Tarmodite that one of the bloods had been thrown for her, and they came and told her about her daughter who was in danger. She went and found that she had died, and the Sages said: She should bring the rest of her offerings and become tahor.

A Kohen Gadol and a nazir may not become tamei [from contact] with their relatives, but they may become tamei with an abandoned corpse. [If] they were traveling on the way, and they found an abandoned corpse —- R’ Eliezer says: The Kohen Gadol should become tamei, but the nazir should not become tamei. But the Sages say: The nazir should become tamei, but the Kohen Gadol should not become tamei. R’ Eliezer said to them: The Kohen should become tamei, since he does not bring a sacrifice for his tumah; but the nazir should not become tamei, since he brings a sacrifice for his tumah. They said to him: The nazir should become tamei, since his sanctity is not everlasting; but the Kohen should not become tamei, since his sanctity is everlasting.

[For contamination] from the following sources of tumah the nazir must shave: for a corpse, or an olive’s bulk of a corpse, or an olive’s bulk of netzel, or a ladle full of decayed corpse, or the spinal column, or the skull, or a limb [severed] from a corpse, or a limb [severed] from a liv- ing body that has on it sufficient flesh, or half a kav of bones, or half a log of blood —- [whether their contamination is transmitted] by contact, carrying, or a roof; and for [tumah from] a bone the size of a barley-grain —- [whether its contamination is transmitted] by contact or by carrying. For these a nazir shaves, sprinkles on the third and seventh day, forfeits the previous days, and does not resume counting until he becomes tahor and brings his sacrifices.
