MISHNAH. [IF A MAN SAYS,] 'I INTEND TO BE A NAZIRITE FOR THIRTY DAYS PLUS AN HOUR,' HE BECOMES A NAZIRITE FOR THIRTY-ONE DAYS, SINCE THERE IS NO NAZIRITESHIP FOR HOURS. GEMARA. Rab said: This applies only when he says, 'thirty-one days,' but if he says, 'thirty days plus one day,' he becomes a nazirite for two periods. Rab follows R. Akiba whose method it was to lay stress on superfluities of expression, as we have learnt: [If a man sells a house, the sale includes] neither the cistern nor the cellar, even though he inserted the depth and the height [in the deed of sale]; he must, however, purchase for himself a right-of way. This is the opinion of R. Akiba, but the Sages say that he need not purchase a right-of-way for himself. R. Akiba does admit, however, that if he explicitly excludes [pit and cellar], he does not have to purchase a right-of-way.
