Leviticus 16:11-19 - The Sin Offering Sacrificial Procedures
11 And Aaron shall bring the ox of his sin offering, and reconcile for himself and for his household, and kill him. 12 "And then he shall take a censer full of burning coals out of the altar that is before the LORD, and his handful of sweet cense beaten small, and bring them within the veil, 13 and put the cense upon the fire before the LORD: that the cloud of the cense may cover the mercy seat that is upon the witness, that he die not. 14 And he shall take of the blood of the ox and sprinkle it with his finger before the mercy seat eastward: even seven times.
15 Then shall he kill the goat that is the people's sin offering, and bring his blood within the veil, and do with his blood as he did with the blood of the ox, and let him sprinkle it toward the mercy seat, and before the mercy seat: 16 and reconcile the holy place from the uncleanness of the children of Israel, and from their trespasses and all their sins. And so let him do also unto the tabernacle of witness that dwelleth with them, even among their uncleannesses. 17 "And there shall be nobody in the tabernacle of witness, when he goeth in to make an atonement in the holy place, until he come out again. And he shall make an atonement for himself and for his household, and for all the multitude of Israel. 18 Then he shall go out unto the altar that standeth before the LORD, and reconcile it, and shall take of the blood of the ox and of the blood of the goat, and put it upon the horns of the altar round about, 19 and sprinkle of the blood upon it with his finger seven times, and cleanse it, and hallow it from the uncleannesses of the children of Israel.
