Midrash su Levitico 14:10

1) (Another proof for the above") R. Yehudah b. Betheirah says: It is written (Vayikra 14:21): "And if he is poor … (then he brings) a tenth-part of fine flour." Just as we find that a poor man brings one beast and one tenth-part, so a rich man, who brings three beasts, brings three tenth-parts. How, then, am I to satisfy "and three tenth parts of (an ephah of) fine flour for a meal-offering mixed with oil"? (That it is to be understood as) for the beasts.

2) (Vayikra 14:10) "and one log of oil": (Why write "one" instead of "a"?) For (if it were written "a," I would think that) just as we find that a poor man, who brings one tenth-part brings one log of oil, so, a rich man, who brings three tenth-parts, requires three logs of oil. It must, therefore, be written "and one log of oil."

7) (Vayikra 14:10) ("And on the eighth day he shall take two he-lambs without blemish, and one ewe-lamb of its first year, without blemish, and three tenth parts of (an ephah of) fine flour for a meal-offering mixed with oil, and one log of oil.") On the seventh day he shaves and on the eighth day he brings (his offerings). And if he shaved on the eighth day, he brings his offerings on the ninth day. These are the words of R. Akiva. R. Tarfon queried him: Why is this different from the instance of a Nazirite (who became tamei, about whom you said that if he shaves on the eighth day, he brings his offerings on the same day)? He answered: The cleansing of the Nazirite is dependent on (the passage of) days (and not on shaving), and the cleansing of the leper is dependent on his shaving, and he cannot bring his offerings until the sun has set (on the day of his shaving).
