Midras Imamat 4:5: Sifra

5) (Vayikra 4:5): "And the anointed Cohein shall take (from the blood of the bullock"): "taking" is written here and elsewhere (Shemoth 24:6: "And Moses took half of the blood and put it into basins.") Just as the "taking" there refers to (receiving the blood) in a vessel, here, too, (the "taking" is) in a vessel.

6) "And the anointed Cohein": This tells me only of the (Cohein) anointed with the oil of anointment (i.e., the high-priest). Whence is it derived that the "many-garmented priest" (may also receive the blood)? From "the Cohein." If in the end we are to include a different Cohein, why state: "And the anointed Cohein shall take"? It is a mitzvah for the anointed Cohein to receive (the blood), but if a different Cohein does so, it is kasher.

7) "from the blood of the bullock": of the blood of the life (i.e., the blood with which the life goes out), and not of the blood of the flesh, and not of the blood that is squeezed out. "from the bullock": shall he receive it (to exclude blood that spilled to the ground and was gathered up.) "and he shall bring it (to the tent of meeting"): a (Cohein that is) kasher, and not one who is pasul. "to the tent of meeting" — to exclude his offering for the "distinct" mitzvah (i.e., the she-goat of Yom Kippur), that its blood not be sprinkled on the golden altar, (but on the outer altar.)
