and the 11th. It is a Torah edict that the consecration takes effect with regard to those two animals. Therefore, one cannot infer from this case that an erroneous act of consecration takes effect.

גמ׳ מני מתניתין? לא רבי יוסי ולא רבנן.

Talmud: The Talmud asks: Whose opinion is expressed in the Mishnah, when it rules that one whose request to dissolve his vow was rejected by a halakhic authority counts the duration of his naziriteship from the moment he took the vow, including the days on which he did not observe the halakhot of naziriteship in practice? The Talmud responds: It is neither the opinion of R' Yosei, nor that of the Rabbis.

דתניא: מי שנדר ועבר על נזירותו ⁠— אין נזקקין לו, אלא אם כן מונה בהן איסור כימים שנהג בהם היתר. רבי יוסי אומר: דיו שלשים יום.

As it is taught in a baraita (Tosefta Nedarim 1:6): With regard to one who took a vow of naziriteship and later transgressed his vow of naziriteship by drinking wine, the halakhic authorities do not attend to his request to dissolve his vow, nor do they let him complete his term as a nazirite by sacrificing offerings, unless he counted, i.e., observed, days of the prohibitions of naziriteship for the same number of days in which he behaved with permissiveness concerning the restrictions of a nazirite. Only after he observes the prohibitions of naziriteship for the number of days that his observance lapsed will a halakhic authority hear his request for dissolution, or allow him to bring his offerings. R' Yosei says: 30 days is enough for him. He is required to observe additional days of naziriteship only if he transgressed his vow of naziriteship for 30 days or more.
