Leviticus 16:11–19

¹¹And Aaron shall present the bullock of the sin-offering, which is for himself, and shall make atonement for himself and for his house, and shall slaughter the bullock of the sin-offering which is for himself. ¹²And he shall take the censer full of burning coals of fire from off the altar before Jehovah, and both his hands full of fragrant incense beaten small, and bring it inside the veil. ¹³And he shall put the incense upon the fire before Jehovah, that the cloud of the incense may cover the mercy-seat which is upon the testimony, that he die not. ¹⁴And he shall take of the blood of the bullock, and sprinkle with his finger upon the front of the mercy-seat eastward; and before the mercy-seat shall he sprinkle of the blood seven times with his finger.

¹⁵And he shall slaughter the goat of the sin-offering, which is for the people, and bring its blood inside the veil, and do with its blood as he did with the blood of the bullock, and sprinkle it upon the mercy-seat, and before the mercy-seat; ¹⁶and he shall make atonement for the sanctuary, to cleanse it from the uncleanness of the children of Israel, and from their transgressions in all their sins; and so shall he do for the tent of meeting which dwelleth among them in the midst of their uncleanness. ¹⁷And there shall be no man in the tent of meeting when he goeth in to make atonement in the sanctuary until he come out; and he shall make atonement for himself, and for his house, and for the whole congregation of Israel. ¹⁸And he shall go out unto the altar which is before Jehovah, and make atonement for it; and shall take of the blood of the bullock, and of the goat, and put it upon the horns of the altar round about; ¹⁹and he shall sprinkle upon it of the blood with his finger seven times, and cleanse it, and hallow it from the uncleannesses of the children of Israel.
