‘‘New growth’’ saves from blond hair and from expansion, [whether] together or scattered, surrounded or not surrounded. ‘‘Remaining hair’’ saves from blond hair and from expansion, [whether] together or scattered, [but only] surrounded; [when it is] on the side it does not save unless it is two hair-spaces distant from where the hair grows normally. One blond [hair] and one black [hair], [or] one blond [hair] and one white [hair] do not save.

How do we shave a nesek? He shaves around it, leaving two hairs immediately adjacent to it, so that spreading will be noticeable. [If the Kohen] confirmed [the nesek] with blond hair, which disappeared and reappeared, or there was an expansion — either initially, at the end of the first week, at the end of the second week, [or] after having been declared tahor — [the nesek] maintains its previous status. [If the Kohen] confirmed [the nesek] with expansion, which disappeared and returned, and the same with blond hair — at the end of the first week, at the end of the second week, [or] after having been declared tahor — it remains as it was.

Two nesakim, side by side, are separated by a row of hair. [If the row of hair is then] split in one place, [the nesakim] are tamei; in two places, [the nesakim] are tahor. How wide must the opening be? Two hairs wide. [If the row of hair] split in [only] one place, [even if it split the width of] a gris, [the nesakim] are tamei.

Two nesakim, one inside the other, are separated by a row of hair. [If the row of hair] split in one place, [the affected person] is tamei. [If it split] in two places, he is tahor. How wide must the opening be? Two hairs wide. [If the row of hair] split in one place [the width of] a gris, [the nesakim] are tahor.
