Merely Growing his Hair

Rav Sheravya asks from our Mishna, which stated that he does not have to redo the days of nezirus that he had already observed and he can start counting right away. Now, if the Mishna is referring to a case of a thirty-day nezirus, how can it rule that he does not forfeit the days that he had already observed? He needs to count another thirty days in order for him to have a thirty-day growth of hair! It must be referring to a case where he declared a long nezirus, but the Mishna states that he can start counting right away. [This implies that the days of tzaraas are not counted towards his term of nezirus. This is direct contrast to Rav Chisda’s ruling!]

Rav Sheravya himself answers the question: The Mishna is referring to a case where he declared to be a nazir for fifty days, and he became a metzora after twenty days. He must undergo the purification process for a metzora and then he counts another thirty days, for then he will have a thirty-day growth of hair.

Tosfos notes that the Gemora could have stated a case where he declared to be a nazir for forty days, and he became a metzora after ten days. He must undergo the purification process for a metzora and then he counts another thirty days, for then he will have a thirty-day growth of hair.

The Brisker Rav asks: Couldn’t the Mishna be referring to a case where he declared to be a nazir for one hundred days, and he became a metzora after seventy days. He would not forfeit the original days, and the days that he was a metzora will not count towards his nezirus, for he needs to have a thirty-day growth of hair. When the purification process is completed, he will be compelled to count another thirty days!

He answers that if there are not thirty days remaining from the time that the purification process is completed, the days that he was a metzora will not count at all, and the days that he observes afterwards will be days of an actual nezirus; not only days where he is growing his hair. This is true only if he did not have a fulfillment of thirty days before he became a metzora; however, if he became a metzora after thirty days, then even if when the purification process is completed, he does not have thirty days remaining, the days that he was a metzora counts towards the nezirus, and the days of waiting afterwards are merely days where he is growing his hair. They are not regarded as days of nezirus!
