Terumah, terumat maaser of demai, hallah and bikkurim, are neutralized in a hundred-and-one mixture. And they are reckoned together [to form the statutory minimum]. And it is necessary to remove [from the mixture an amount equal to that of the consecrated produce contained in it]. Orlah and kilayim of the vineyard are neutralized in a two-hundred-and-one mixture. And they are reckoned together [to form the statutory minimum]. But it is not necessary to remove [from the mixture an amount equal to that of the consecrated produce contained in it]. Rabbi Shimon says: they are not reckoned together. Rabbi Eliezer says: they are reckoned together when they impart flavor, but not to prohibit.

Terumah can void orlah, and orlah can void terumah. How so? [For instance] a seah of terumah fell into one hundred, and afterwards three kavs of orlah or three kavs of mixed-seeds of the vineyard [fell in]. This is [an instance] where terumah goes towards neutralizing orlah, and orlah terumah.

Orlah can void kilayim, and kilayim [can void] orlah, and orlah [can void] orlah. How so? A seah of orlah falls into two hundred [seahs] and afterwards there falls in a seah and a little bit more of orlah, or a seah and a little bit more of kilayim of the vineyard--this is [a case] where orlah can void kilayim, and kilayim [can void] orlah, and orlah [can void] orlah.

Whatever causes something to ferment, or seasons, or makes medumma with terumah, with orlah or with ‘mixed-seeds’ of the vineyard, is prohibited. Bet Shammai says: it also renders unclean. But Bet Hillel says: it never renders unclean unless it has the volume of an egg.

Concerning what did they say: “Anything that causes fermentation or seasons or which renders medumma we rule stringently”? [In the case of] a species [mixed] with its [like] species. [When did they say] “we rule [sometimes] leniently and [sometimes] stringently”? [In the case of] a species [mixed] with a different kind of species. How so? If leaven of wheat fell into dough of wheat and there is enough to cause fermentation, [then] whether there is enough to become neutralized in one-hundred-and-one, or there is not enough to become neutralized in one-hundred-and-one, it is prohibited. If there is not enough to become neutralized in one-hundred-and-one, [then] whether there is enough to cause fermentation, or there is not enough to cause fermentation, it is prohibited.

[We rule sometimes] leniently and [sometimes] stringently, [in the case of] a species [mixed] with a different kind of species. How so? If crushed beans were boiled together with lentils, and there is enough of them [the crushed beans] to impart flavor, [then] whether there is enough to become neutralized in one-hundred-and-one, or there is not enough to become neutralized in one-hundred-and-one, it is prohibited. [But] if there is not enough to impart flavor, [then] whether there is enough to become neutralized in one-hundred-and-one, or there is not enough to become neutralized in one-hundred-and-one, [the mixture] is permitted.

If leaven of hullin has fallen into dough, and there was enough of it to cause fermentation, and after that leaven of terumah fell in or leaven of kilayim of the vineyard, and there is enough to cause fermentation, [the dough] is prohibited.

If leaven of hullin has fallen into dough and caused it to ferment, and after that there fell in leaven of terumah or of kilayim of the vineyard, and there was enough to cause fermentation, [the dough] is prohibited. But Rabbi Shimon permits it.

Seasonings [consisting] of two or three categories of one species, or [consisting] of three species [of one category], are forbidden and combine. Rabbi Shimon said: Two or three categories of one species, or two species of one category, do not combine.

Leaven of hullin and of terumah fell into dough, and neither this was sufficient to cause fermentation nor was that sufficient to cause fermentation, but together they caused [the dough] to ferment:Rabbi Eliezer says: I go after the last. But the sages say: whether the prohibited fell in first or last, it never causes the dough to become prohibited unless there is enough to cause fermentation.

Yoezer, master of the temple (Ish Habirah), was one of the disciples of Bet Shammai and he said: I asked Rabban Gamaliel the elder as he was standing at the eastern gate [of the Temple], and he said: it never causes the dough to become prohibited unless there is enough to cause fermentation.

Vessels which were oiled with unclean oil, and [later] he returned and oiled them with clean oil; Or he [first] oiled them with clean oil, and [later] he returned [to them] and oiled them with unclean oil: Rabbi Eliezer says: “I go after the first.” And the sages say: after the last.

Leaven of terumah and of kilayim of the vineyard which fell into dough, this one is not sufficient to cause fermentation, nor is that one sufficient to cause fermentation, but together they cause fermentation:It [the dough] is prohibited to non-priests and permitted to priests. Rabbi Shimon permits it to both to non-priests and to priests.

Seasonings of terumah and of kilayim of the vineyard that fell into a dish, and there is not enough of one to season, nor is there of the other to season, but together they seasoned:It [the dish] is prohibited to non-priests but permitted to priests. Rabbi Shimon declares it permitted to non-priests and to priests.

A piece of [meat from] one of the most holy [sacrifices] and [a piece] of [meat which is] piggul, or remnant, which were cooked with other pieces, it [the non-sacred meat] is prohibited to non-priests but permitted to priests. Rabbi Shimon declares it permitted to non-priests and to priests.

Meat of most holy [sacrifices] and meat of less holy [sacrifices] were cooked together with ordinary meat: [the dish] is prohibited to the unclean, but permitted to the clean.
