Leviticus 4:25
And the priest shall take of the blood of the sin offering with his finger, and put it upon the horns of the altar of burnt offering, and shall pour out his blood at the bottom of the altar of burnt offering.
And the priest shall take of the blood of the sin offering with his finger,.... With the finger of his right hand, as the Talmudists {n} observe, and Gersom on the place; the priest first received the blood into a basin or ministering vessel, and then dipped the finger of his right hand into it, that next the thumb:
and put it upon the horns of the altar of burnt offering; the four horns of it; in this there was a difference between the sacrifice of the anointed priest and of the congregation, and this of the ruler; the blood of the former was put upon the horns of the altar of incense, this upon the horns of the altar of burnt offering:
and shall pour out his blood at the bottom of the altar of burnt offering; the South bottom of it; the order of the priest's proceeding in putting the blood was different from that used in putting it on the horns of the altar of incense; here he first put the blood upon the southeast horn, then upon the northeast, next upon the northwest, and then upon the southwest; and upon the bottom of that horn where he finished, he poured the remainder of the blood, which was the southern bottom {o}.
