But has he [the Tanna] not stated this once already? — It might be thought that this is only true for one naziriteship but not for two, and so we are told [that it is also true for two]. We have learnt: Should he poll on the day prior to the sixtieth, he has fulfillied his obligation. since the thirtieth day is included in the [required] number.
