Leviticus 16:16-19

16So he shall make atonement for the Holy Place, because of the uncleanness of the children of Israel, and because of their transgressions, for all their sins; and so he shall do for the tabernacle of meeting which remains among them in the midst of their uncleanness.

17There shall be no man in the tabernacle of meeting when he goes in to make atonement in the Holy Place, until he comes out, that he may make atonement for himself, for his household, and for all the assembly of Israel.

18And he shall go out to the altar that is before the Lord, and make atonement for it, and shall take some of the blood of the bull and some of the blood of the goat, and put it on the horns of the altar all around.

19Then he shall sprinkle some of the blood on it with his finger seven times, cleanse it, and consecrate it from the uncleanness of the children of Israel.
