Leviticus 16:14-16

American Standard Version

¹⁴ and he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy-seat on the east; 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 veil, and do with his 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 atonement for the holy place, because of the uncleannesses of the children of Israel, and because of their transgressions, even all their sins: and so shall he do for the tent of meeting, that dwelleth with them in the midst of their uncleannesses.
