(Mishnah): One who gathers moist grasses may eat them without Biur until the moisture (of the earth that sweetens the fruits) dries up. One who gathers dry grasses may eat them without Biur until the second rains fall. Cane and vine leaves (gathered when moist) may be eaten without Biur before they fall off from their stems. But if gathered when dry, it's until the second rains fall.

(R. Akiva): All are until the second rains fall.

Similarly, one who rents a house 'until the rains' has it until the second rains fall. One who vows not to derive benefit from someone 'until the rains' is prohibited until the second rains fall.

Until when may the poor enter the orchards (to gather the gifts to the poor or to gather Sheviis produce)? Until the second rains fall. Until when may one use and burn the straw and stubble of Sheviis? Until the second rains fall.

(Gemara) (R. Avin citing R. Yochanan): The Mishnah's text should not say 'cane leaves'; only vine leaves. Cane leaves don't need Biur.

Support (Baraisa): Cane leaves, Og leaves and carob leaves do not require Biur, because they don't disappear (they just dry out).

Question (R. Zeira): (In the case of renting out a house) what if he said 'until the rain'? (Does he mean until the rains or until one rainfall?)

Answer: Until one rainfall.

Mishnah in Maseches Shekalim: One who says, "I accept to bring wood (plural)'' (as a donation for the altar), he should not bring less than two logs.

Question (R. Yosi b' R. Bun citing R. Ba bar Mamal): One who says, "I accept to bring wood (sing.)'', may he bring only one log?

(R. Eliezer): The Mishnah (in Maseches Yoma) teaches this - The two Kohanim were carrying two logs (one each). This shows that each is a separate Korban.

Baraisa (R. Yosi): Any case listed in the Mishnah that depends on the actual rainfall (e.g. gathering dry cane and vine leaves) is until the second rains fall. Any case that doesn't depend on the actual rainfall (e.g. renting a house) is until the time that the second rains usually fall.

Tosefta (Rabban Shimon ben Gamliel): If rains fell for 7 days without stopping, it is considered to be the first and second rains.

Baraisa (R. Chanina citing Rabban Shimon ben Gamliel): Why are the rains referred to as 'Revi'ah'? Because they rest onto top of the ground (and fertilize it).

(R. Chanina): (Discussing the Mishnah's case of straw and stubble) Once the straw and stubble in the field has rotted (it loses its sanctity of Sheviis and) even that which is in house becomes permitted.

Baraisa (R. Hoshiya): Even after 3 years, it remains prohibited until it rots.

One may not soak Sheviis stubble in mud (for construction), but if he had already soaked it, it is annulled to the mud (and it loses its sanctity). Sheviis stubble may not be used to fill a pillow, but if it was it is annulled to the pillow and he may sleep on it.

Question: Is there a prohibition of Sefichin on Sheviis stubble?

R. Levi of Tzanbar asked this question to R. Ba bar Zavdi and he permitted it.

(R. Zeira): I didn't rely on R. Bar bar Zavdi and I asked the Chachamim of Beis Karsana, who said, "We were accustomed to collect stubble before Sheviis for the entire year ahead, so that we wouldn't use Sefichin of stubble; and when we ran out, we would gather stubble that grew on walls (for which there was no decree of Sefichin).

(R. Yirmiyah): A Baraisa permits it, as it was taught - the painters and those that fatten fowl (for consumption), may buy chicken feed (shells and chaff of produce) from anywhere without concern (that they are Sefichin. Chazal didn't decree on them since they aren't human food.)

R. Yirmiyah suggested that one may also buy from someone suspected of not observing Sheviis.

(R. Yosi to R. Yirmiyah): They only allowed it when the seller's status was unknown, but not if he was certainly suspected.

(R. Shammai): The Mishnah in Maseches Terumos (Perek 10 Mishnah 5) teaches that even stubble is prohibited - (If fenugreek, whose seeds and stems have the same taste, fell into a vat of wine) If the fenugreek was of Sheviis, Kila'i HaKerem (mixed seeds in a vineyard) or Hekdesh, if the seed and stem combined are enough to give flavor, the wine is prohibited.

Question: (The Mishnah asked - Until when may one use and burn the straw and stubble of Sheviis? Until the second rains fall.) How is it permitted to burn them - isn't it destroying Sheviis produce?

Answer: For a human need, it is permitted to benefit from animal food in this way.

Answer (R. Mana): (This answer is incorrect. Rather) it's when the time of Biur arrived and since they have lost their sanctity, he may benefit from burning them - and there is no proof that one may benefit from animal food for a human need.
