Midrash su Levitico 6:16

4) (Vayikra 6:16) ("And every meal-offering of a Cohein shall be entirely (smoked); it shall not be eaten.") The meal-offering of a Cohein is not eaten. The meal-offering of the daughter of a Cohein is eaten. This tells me only of his required meal-offering (above, the griddle meal-offering). Whence do I derive the same for his gift meal-offering? From "every meal-offering of a Cohein." This tells me (that he transgresses only if he eats) all of it. Whence do I derive the same for (his eating) part of it? From "shall it be" — even part of it. This tells me only that the above (Vayikra 6:15) (the griddle meal-offering) comes under "it shall be entirely smoked" and that the lower (Vayikra 6:16) (the gift meal-offering comes under "it shall not be eaten" Whence do I derive that the upper (also) comes under "it shall not be eaten" and the lower under "it shall be entirely smoked"? From the identity of "entire" (kalil, in both instances, so that what applies to one applies to the other). R. Eliezer says: "It shall be entirely (kalil) smoked; it shall not be eaten" — "All that comes under kalil" (even a burnt-offering and devoted portions, which are to be entirely consumed) — if he eats them, he transgresses a negative commandment.

11) (Vayikra 5:13): "and it shall be to the Cohein": That is, the meal-offering service of the Cohein (if he himself is the sinner) can be performed by the Cohein himself. Or perhaps its intent is only to permit (the eating of what remains of) the tenth of an ephah of a Cohein (who sinned). And how would I satisfy (Vayikra 6:16): "And every meal-offering of a Cohein shall be entire, (exclusively for the L–rd); it shall not be eaten"? By his donative meal-offering; but his one tenth of the ephah may be eaten. It is therefore, (to negate this) written ("and it shall be to the Cohein) as a meal-offering" — as his donative meal-offering. Just as his donative meal-offering is not eaten, so the tenth of the ephah is not eaten. R. Shimon says: "and it shall be to the Cohein as a meal-offering": The tenth of an ephah of a Cohein is like the tenth of the ephah of an Israelite, viz. Just as a fistful is taken of the tenth of the ephah of an Israelite, so a fistful is taken of this tenth of an ephah (of a Cohein).
