Leviticus 16:11-16

11“Then Aaron shall offer the bull of the 1sin offering 2which is for himself and make atonement for himself and 3for his household, and he shall slaughter the bull of the 4sin offering which is for himself. 12He shall take a 5firepan full of coals of fire from upon the altar before the Lord and 6two handfuls of finely ground 7sweet incense, and bring it inside the veil. 13He shall put the incense on the fire before the Lord, so that the cloud of incense may cover the 8atoning cover that is on the ark of the testimony, 9otherwise he will die. 14Moreover, 10he shall take some of the blood of the bull and sprinkle it 11with his finger on the atoning cover on the east side; also in front of the atoning cover he shall sprinkle some of the blood with his finger seven times.

15“Then he shall slaughter the goat of the sin offering, 12which is for the people, and bring its blood inside the veil and do with its blood as he did with the blood of the bull, and sprinkle it on the atoning cover and in front of the atoning cover. 1613He shall make atonement for the Holy Place, because of the impurities of the sons of Israel and because of their unlawful acts regarding all their sins; and he shall do so for the tent of meeting which remains with them in the midst of their impurities.
