Leviticus 16:15

12 And he shall take a censer full of burning coals of fire from off the altar before the LORD, and his hands full of sweet incense beaten small, and bring [it] within the vail:

13 And he shall put the incense upon the fire before the LORD, that the cloud of the incense may cover the mercy seat that [is] upon the testimony, that he die not:

14 And he shall take of the blood of the bullock, and sprinkle [it] with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times.

15 Then shall he kill the goat of the sin offering, that [is] for the people, and bring his blood within the vail, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy seat, and before the mercy seat:

16 And he shall make an atonement for the holy [place], because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.

17 And there shall be no man in the tabernacle of the congregation when he goeth in to make an atonement in the holy [place], until he come out, and have made an atonement for himself, and for his household, and for all the congregation of Israel.

18 And he shall go out unto the altar that [is] before the LORD, and make an atonement for it; and shall take of the blood of the bullock, and of the blood of the goat, and put [it] upon the horns of the altar round about.
