One who prepares dough from wheat and from rice, Rabbi Shimon ben Gamaliel says, she is not liable in challah until the grain [itself] has [at least] the minimum quantity, and a person does not fulfill his obligation on Passover until [the matzah] has [at least] the minimum quantity.

One who removes leaven from dough from which challah has not been raised up (i.e., separated), and puts it inside dough from which challah has been raised up, behold, this one brings flour from a different place and combines it [with the first batch] so that [it is at least] five-fourths [of a kav] in order to render it liable according to the calculation [of the quantity of the new dough and the leaven].

A kav on one side, and a kav on the other side, and a kav of new grain in the middle; a kav on this side, and a kav on that side, and a kav of barley in the middle, behold, they combine together [to form a quantity of dough that is liable in challah]. [The Sages then] added to [the list]: A kav on this side, and a kav on that side, and a kav from another woman in the middle; or a kav on this side and a kav on that side, and a kav of something whose challah had already been removed in the middle, behold, these combine together. A kav on this side, and a kav on that said, and a kav of a Gentile in the middle; a kav on this side, and a kav on that side, and kav of rice in the middle; a kav on this side, and a kav on that side, and a kav of terumah* in the middle, these do not combine together. A kav of wheat and a kav of barley and a kav of spelt in the middle, behold, these combine*, [but] when he takes terumah, he takes terumah from each and every one [separately], for one does not take terumah from one species on behalf of a different species. Half a kav of wheat and half a kav of barley and half a kav of spelt, he removes challah from the spelt [on behalf of all three]. Said Rabbi Eliezer ben Yaakov, one who removes challah from a kav (i.e., less than the minimum quantity to render dough liable), to whom is he similar? To one who takes terumah from produce that has not grown to [at least] a third [of its expected size], for his terumah is not terumah. *And the Sages say, [he is similar] to one who takes terumah from fruits that did not complete their work, for his terumah is not terumah (Ter. 1:10). They went back and said, neither this nor that; for behold, this kav is able to combine with others.

Impure flour that got mixed up with pure flour, and there is not enough of the impure [to render one liable in challah], once he removes it, he says, behold, this is challah, except for the impure that is inside it. Impure wheat that got mixed up with pure wheat and there is not enough of the impure, once he takes terumah, he says, behold, this is terumah, except for the impure that is inside of it.

Said Rabbi Elazar son of Rabbi Tzadok, even though Rabban Gamaliel exempted tenants of land in Syria, it is forbidden to be a land tenant [in the first place in Syria], [but] if one was a land tenant, behold, he is exempt as long he does not harvest [produce] and others bundle on his behalf, or harvest grapes and others tread on them on his behalf, or harvest olives and others press them on his behalf. Rather, they harvest [produce] and he bundles on their behalf, they harvest grapes and he treads on them on their behalf, and they harvest olives and he presses them on their behalf. And so too Rabbi Elazar son of Rabbi Tzadok says, Rabban Gamaliel did not render one liable in Syria except for one [portion of] challah only.

One who purchases from a baker in Syria needs to separate challah as demai, the words of Rabban Gamaliel. And the Sages say, there is no need to separate challah as demai. From the river south of Cheziv and onward, two [portions] of challah [must be separated] as demai. Rabbi Shimon says, if he did not raise up the first of [at least] the minimum quantity, he may not do so from the second.

Loaves of Gentiles outside the Land [of Israel] and terumah of Gentiles outside the Land, they let him know (מודיעין אותו (see Lieberman)) that it is not liable in challah, and it may be eaten by non-Kohanim.

Twenty-four priestly gifts were given to Aharon and his sons, in particular, in general and with an everlasting covenant. These are they: ten in the Temple, four in Jerusalem and ten in the surrounding environs. Ten in the Temple: sin offering, guilt offering, communal peace offerings, bird sin offerings, conditional guilt offerings, the oil of the leper's offering, the two loaves of Shavuot, the weekly showbread, the remains of the flour offerings and the Omer offering. Four in Jerusalem: first born animals, first fruits, the elevated portions of the thanksgiving and Nazirite offerings, and the skins of the sacred offerings. Ten in the surrounding environs: the terumah portion of produce, the terumah taken from the Levitical tithe, the first bread (challah), the first fleece, the shoulder, cheek and stomach portion, redemption of the first born male child, redemption of the first born donkey, devoted offerings, a devoted ancestral field which was not redeemed, returned property stolen from a convert who is dead. All of these were give to Aharon and his sons in general, in particular and with an everlasting covenant in order to create an obligation on the whole and on each particular, to grant a reward on the whole and on each particular. One who transgresses and withholds them is as if they transgressed both on the whole and the particular.

What is considered "the Land [of Israel]" and what is considered "outside the Land [of Israel]"? From the slopes of Taurus Amanus inwards is the "Land of Israel," from Taurus Amanus to the outside is "outside the Land." About the islands in the sea, one looks at them as if a string were drawn from Taurus Amanus to the rivers of Egypt: from the string to the inside is the "Land of Israel," from the string to the outside is "outside the Land." Rabbi Yehudah said, all that lies before the Land of Israel is like the Land of Israel since it is said (Num. 34:6): “The Eastern border shall be for you the Great Sea as border.” It is as if a string were drawn from Cephalaria to the Ocean, inside the string is the "Land of Israel," and outside is "outside the Land."

A boat that comes from outside the Land to the Land, and it had dough in it: [If it entered the land] before a crust formed on its surface, it is liable. Once a crust formed on its surface, it is exempt.
