Leviticus 9:12

And he slew the burnt offering
The ram, which was for himself also; this he slew at the north side of the altar, ( Leviticus 1:11 ) and Aaron's sons presented unto him the blood:
which they had received into a basin, when it was slain: which he sprinkled round about upon the altar;
as he had seen Moses do before him, ( Leviticus 8:19 ) .
