[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].
