[Regarding] challah and terumah, one is liable to death for [illegally eating] them and to [a surcharge of] a “fifth,” they are for-bidden to non-Kohanim, they are the property of the Kohen [to whom they are given], they are nullified in [a mixture of] one hundred and one [parts], they require hand-washing and sunset, they may not be taken from [produce which is] tahor on be-half of [produce which is] tamei, [and] only from that which is in [their] proximity and from something “finished.”  One who says, “My entire [crop in the] silo is terumah,” or “My entire dough is challah” has said nothing, unless he leaves over a small amount [as chullin].

[Regarding] produce from outside the Land [of Israel] which entered the Land —- it is obligated in challah.  [If produce] was exported from here to there —- R' Eliezer obligates [it in challah], but R' Akiva exempts [it].

[Regarding] soil from outside the Land [of Israel] which was brought on a boat to the Land [of Israel] —- [produce growing in it] is obligated in tithes and in [the laws of] Sheviis. R' Yehudah said: When [is this so]? When the boat is touching [the ground].  [Regarding] a dough which was kneaded with fruit juice —- it is obligated in challah, and it may be eaten with unclean hands.

A woman may sit and set aside her challah while naked, because she is able to cover herself; but not a man.  [If] one is unable to make his dough in [a state of] taharah —- he should make it kav portions, but should not make it in tumah. But R' Akiva says: He should make it in tumah, but should not make it kav portions; for just as one designates [challah] for a tahor [dough], so he designates [challah] for a tamei [dough] —- he assigns the designation “challah” to [a portion of] this [tahor dough] and he assigns the designation “challah” to [a portion of] this [tamei dough]; but kav portions have no share in the designation [“challah”].
