R' Yehoshua and R' Yakim, leader of Hadar, testified regarding a jug of cha-tas ashes that one placed upon a sheretz, that [the ashes] are tamei; for R' Eliezer rules [the ashes] tahor. R' Papyas testified regarding one who declared two terms of nezirus, that if he shaved for the first [nezirus] on day thir-ty, then he shaves for the second [nezirus] on day sixty. But if he shaved on day sixty-minus-one, he has discharged his obliga-tion, because day thirty is reckoned for him in the count.
