Leviticus 9:9 - Ellicott's Commentary On The Whole Bible

And the sons of Aaron brought the blood. — His sons, for whom the sacrifice was offered as well as for himself, and who assisted at the ritual, after catching the blood in a bowl (see Leviticus 1:5), brought it to Aaron, who stood at the altar waiting to receive it. Unlike the ordinary law of the sin offering for the high priest and for the people, the blood of which was taken into the tabernacle (see Leviticus 4:7; Leviticus 4:16-18), Aaron on this occasion simply put some of it upon the four horns of the brazen altar as Moses had done in the sin offering of consecration (see Leviticus 8:15), for, though high priest, he had not as yet access to the holy place of the sanctuary till he had qualified himself by this sacrifice in the court-yard.
