Leviticus 4:18

‘The priest shall also put some of the blood on the horns of the altar of fragrant incense which is before Yahweh in the tent of meeting; and all the blood of the bull he shall pour out at the base of the altar of burnt offering which is at the doorway of the tent of meeting.

‘Then the priest shall take some of the blood of the sin offering with his finger and put it on the horns of the altar of burnt offering; and the rest of its blood he shall pour out at the base of the altar of burnt offering.

‘And the priest shall take some of its blood with his finger and put it on the horns of the altar of burnt offering; and all the rest of its blood he shall pour out at the base of the altar.

‘And the priest shall take some of the blood of the sin offering with his finger and put it on the horns of the altar of burnt offering, and all the rest of its blood he shall pour out at the base of the altar.

‘He shall also sprinkle some of the blood of the sin offering on the side of the altar, while the rest of the blood shall be drained out at the base of the altar: it is a sin offering.

‘But no sin offering, of which any of the blood is brought into the tent of meeting to make atonement in the holy place, shall be eaten; it shall be burned with fire.

“And he shall take from the congregation of the sons of Israel two male goats for a sin offering and one ram for a burnt offering.

So they slaughtered the bulls, and the priests took the blood and splashed it on the altar. They also slaughtered the rams and splashed the blood on the altar; they slaughtered the lambs also and splashed the blood on the altar.
