He is liable for wine by itself, for grapes by themselves, for grape-seeds by themselves, and for grape-skins by themselves. R’ Elazar ben Azariah says: He is not liable until he eats two grape-seeds and their grape-skin.  Which are chartzanim and which are zagim? The chartzanim are the outer part, the zagim are the inner part; [these are] the words of R’ Yehudah. R’ Yose says: [In order] that you not err, it is like the zug-bell of an animal —- the outer part [is called] zug, and the inner part inbal.

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.
