Midrash su Levitico 7:12

1) (Vayikra 7:11) ("And this is the law of the sacrifice of peace-offerings which one shall offer to the L–rd. (Vayikra 7:12) If for thanksgiving he shall offer it, then he shall offer with the sacrifice of thanksgiving, unleavened cakes mixed with oil, and unleavened cakes spread with oil, and cakes of soaked fine flour mixed with oil.") What is the intent of (Vayikra 7:11) "which one shall offer" (and (Vayikra 7:12) "he shall offer it")? (It could simply have been written "If for thanksgiving, then he shall offer, etc.") (They are written for the following purpose:) Whence do we derive that if one set aside his thank-offering and it was lost, and he set aside a different one in its place, after which the first was found, so that now both are standing before him — whence do we derive that he may offer up whichever he wishes, and its loaves along with it? From (a thank-offering) "which one shall offer." I might think that both required loaves. It is, therefore, written "he shall offer it" — one requires loaves and not both.

2) "soleth mixed (with oil"): We are hereby taught that it is mixed (with oil) while it is soleth. Rebbi says: It is (thus) mixed (when they are at the stage of) challoth, viz. (Vayikra 2:4): "challoth … mixed" — whereupon they said to him: Are not "challoth" mentioned in respect to the thanksgiving loaves (Vayikra 7:12), and it is impossible to mix them (with oil) when they are challoth, (there being too little oil for that); but (it must be that the oil is mixed with) soleth. How is this done? He places oil in the vessel before processing (the meal-offering). Then he places oil on it (the soleth), and mixes it, and kneads it, and breaks it into pieces, and pours oil on it, and takes the fistful. Rebbi says: He mixes them (with oil) when they are challoth, viz.: "challoth … mixed with oil." How is this done? He places oil in the vessel before processing it, and places (oil) on it, and kneads it, and bakes it, and crumbles it, and places oil on it, and mixes it, and then again pours oil on it, and takes the fistful. "unleavened": I might think that this is a mitzvah specification only; it is, therefore, written "shall it be" — Scripture makes it a categorical requirement.

2) But does it not follow a fortiori (that lan obtains in a bamah), viz.: If a bird, which is not rendered unfit (as an offering) by a blemish, is rendered unfit by lan, bamah offerings, which are rendered unfit by a blemish — how much more so should they be rendered unfit by lan! — No, why is it that a bird, even though it is not rendered unfit by a blemish is rendered unfit by lan? Because (sacrifice by) a zar (a non-Cohein) renders it unfit. But would you, therefore, say of bamah offerings that because a blemish renders them unfit, lan should render them unfit? (This is not so,) because a zar does not render them unfit. And because a zar does not render them unfit, lan should not render them unfit! It is, therefore, written (Vayikra 7:11): "And this is the law of the sacrifice of peace-offerings … (Vayikra 7:12) If for thanksgiving he shall offer it, etc." (i.e., there is one law for all offerings, whether in the tent of meeting or in a bamah) — equating the time (and the lan) factor in a bamah with that in the tent of meeting.
