Midrash sobre Levítico 23:17

1) (Vayikra 23:17) ("From your dwellings shall you bring two breads of lifting. Two tenths of fine flour shall they be. Of leaven shall they be baked, first fruits to the L–rd.") "From your dwellings": and not from outside Eretz Yisrael. "From your dwellings": even from the attic (i.e., even from old grain if no new grain is available). "shall you bring": What you bring elsewhere (the thanksgiving loaves) should be (of the same measure) as this. Just as this is one-tenth to a loaf, so, what you bring elsewhere must be one-tenth to a loaf.

2) "the meal-offering of your bikkurim": I might think this is an individual offering, (but) it is written here "bikkurim," and, elsewhere, (in respect to the two loaves, Vayikra 23:17): "bikkurim." Just as "bikkurim" there are a communal offering, so, bikkurim here. These are the words of R. Akiva. R. Shimon says: I might think this is an individual offering, but (this is negated by) its being written (Vayikra 23:14): "And you shall bring the omer, the first (grain) of your harvest, to the Cohein." If you say that this (in our verse) is an individual offering, and that is a communal offering, this cannot be. For if this is "bikkurim to the L–rd," then that is not the first of the harvest; and if that is the first of the harvest, then this is not "bikkurim to the L–rd." (Note:) Things omitted here (in connection with the omer offering [e.g., "waving" and the permitting of chadash (the new crop)] are written there.

2) "breads of lifting two": They should look alike. "Two tenths": in sum total. "of fine flour shall they be; of leaven shall they be baked": He extracts it (the leaven) from themselves (the two loaves to be baked) and from their leaven. These are the words of R. Meir. R. Yehudah says: This, too, is not "select." Rather he brings leaven (from elsewhere) and he places it into the (one-tenth) measure and fills it up (with fine flour). R. Meir: That, too, would be lacking (of the exact measure) or more (than it).
