מדרש על ויקרא 2:6

3) (Vayikra 2:6): "You shall break it": I might think only in two; it is, therefore, written: "into pieces." I might then think it should be made into crumbs; it is, therefore, written: "it" — "it" into pieces (so that there are four pieces), and not its pieces into pieces.

4) From here it was derived that the meal-offering of an Israelite (not a Cohein) is doubled into halves and then into quarters and separated (for the taking of the fistful); the meal-offering of Cohanim is doubled into halves and then into quarters, but not separated, (no fistful being taken); the meal-offering of the anointed (high-) priest was not doubled (twice, but only once). R. Shimon says: The meal-offering of Cohanim and the meal-offering of the high-priest did not require doubling, there being no fistful requirement for them; and wherever there is no fistful, there is no doubling. And all of the pieces (after the quartering) are reduced to olive-sizes.

5) "You shall break it into pieces … It is a meal-offering" — to include all meal-offerings for breaking into pieces. I might think that even the two loaves and the show bread are to be broken into pieces; it is, therefore, written: "it" (to exclude the foregoing). Why do you see fit to include all the meal-offerings and to exclude the two loaves and the show bread? After Scripture included, it excluded. Just as these (the other meal-offerings) are unique in that something is taken from them for the fire (of the altar), so, all from which something is taken for the fire (are broken into pieces) — to exclude the two loaves and the show bread, from which nothing is taken for the fire (but which are entirely eaten by the Cohanim).

6) (Vayikra 2:6): "and you shall pour oil upon it; it is a meal-offering" — to include all meal-offerings for pouring of oil. I might think that even a meal-offering baked in an oven (is thus included); it is, therefore, written "upon it." (In that case,) I would exclude (from pouring, only) challoth, (of which the verse [Vayikra 2:5] speaks), but not wafers (baked in an oven); it is, therefore, written (to exclude wafers too): "it (is a meal-offering").

(Lev. 7:12:) IF HE OFFERS IT FORA THANKSGIVING…. See how the Holy One forgives the sins of Israel.³⁰Tanh., Lev. 2:6. So what did they offer to the Holy One? It is simply that the Holy One said: Whoever has a bull, let him bring a bull; and whoever has a calf let him bring a calf. Whoever has a lamb, let him bring a lamb. Whoever has a dove, let him bring a dove. Whoever has only one of all these, let him bring fine flour; and whoever has neither flour nor anything at all, let him bring words. Thus it is stated (in Hos. 14:3 [2]): TAKE YOUR WORDS WITH YOU [AND RETURN UNTO THE LORD]. It is therefore stated (in Lev. 7:12:) IF HE OFFERS IT FOR A THANKSGIVING….
