Nedarim

It was taught: He who vows [to abstain] from dagan is also forbidden dry Egyptian beans; yet moist ones are permitted. He is also permitted rice, grist, groats and pearl-barley. He who vows [to abstain] from the fruits of that year, is forbidden all the fruit of that year, but is permitted goats, lambs, milk, eggs, and fledglings [of that year].  But if he vows, 'The growths of this year [be forbidden] to me,' all these are forbidden. He who vows [abstinence] from the fruits of the earth is forbidden all the fruits of the earth, yet is permitted mushrooms and truffles; but if he vows, 'that which grows from the earth [be forbidden] to me,' all these are forbidden him. But this contradicts the following: For that which does not grow from the earth, one must recite the benediction, 'by whose word all things exist.'  And it was taught: For salt, brine mushrooms, and truffles, 'by whose word all things exist' is said!  — Abaye answered, They do indeed grow out of the earth, but draw their sustenance from the air,  and not from the earth. But he [the Tanna] states: For that which does not grow out of the earth?  — Read: For that which does not draw its sustenance from the earth. MISHNAH. HE WHO VOWS [NOT TO BENEFIT] FROM GARMENTS IS PERMITTED SACK-CLOTH,  CURTAIN,  AND BLANKET WRAPPING. IF HE SAYS, 'KONAM, IF WOOL COMES UPON ME,' HE MAY COVER HIMSELF WITH WOOL FLEECES;  [KONAM] IF FLAX COMES UPON ME', HE MAY COVER HIMSELF WITH FLAX BUNDLES.  R. JUDAH SAID: IT ALL DEPENDS UPON THE PERSON WHO VOWS, [THUS:] IF HE IS LADEN [WITH WOOL OR FLAX] AND PERSPIRES AND HIS ODOUR IS OPPRESSIVE, AND HE VOWS 'KONAM' IF WOOL OR FLAX COME UPON ME,' HE MAY WEAR THEM, BUT NOT THROW THEM [AS A BUNDLE] OVER HIS BACK. GEMARA. It was taught: He who vows [not to benefit] from garments is permitted sack-cloth, curtain, and blanket wrapping. But he is forbidden a belt,  fascia,  scortea, a leather spread, shoes,  knee breeches breeches and a hat. What is a scortea? — Rabbah b. But Huna said: a leather coat. It was taught: One may go out [on the Sabbath] wearing a thick sack-cloth, a coarse blanket, a curtain, and a blanket wrap, to keep off the rain;  but not with a box, basket  or matting for the sane purpose. Shepherds may go out with sacks;  not only shepherds, but all men, but that the Sages spoke of what is usual. R. JUDAH SAID, IT ALL DEPENDS UPON THE PERSON WHO VOWED, etc. It was taught: How did R. Judah say, it all depends upon the person who vows? If he is wearing wool, and he is irritated and he vows 'Konam, if wool comes upon me,' he is forbidden to wear, but permitted to carry it; if he is laden with flax and perspires and vows, 'Konam, if flax comes upon me, he may wear but must not carry it.
