12 Take some of the bull’s blood on your finger and put it on the horns of the altar,+ and pour out all the rest of the blood at the base of the altar.+

15 Moses slaughtered it and took the blood+ with his finger and put it on the horns of the altar on all sides, and he purified the altar from sin, but the rest of the blood he poured at the base of the altar, in order to sanctify it to make atonement on it.
