15 And he killed it, and Moses took the blood, and with his finger put it on the horns of the altar around it and purified the altar and poured out the blood at the base of the altar and consecrated it to make atonement for it.

19 And he killed it, and Moses threw the blood against the sides of the altar.

24 Then he presented Aaron's sons, and Moses put some of the blood on the lobes of their right ears and on the thumbs of their right hands and on the big toes of their right feet. And Moses threw the blood against the sides of the altar.
