Leviticus 16:11-19 - The Sin Offering Sacrificial Procedures
11 "Aaron shall present the bull of the sin offering, which is for himself, and shall make atonement for himself and for his house, and shall kill the bull of the sin offering which is for himself. 12 He shall take a censer full of coals of fire from off the altar before the LORD, and two handfuls of sweet incense beaten small, and bring it within the veil: 13 and he shall put the incense on the fire before the LORD, that the cloud of the incense may cover the mercy seat that is on the testimony, so that he will not die. 14 He shall take some of the blood of the bull, and sprinkle it with his finger on the mercy seat on the east; and before the mercy seat he shall sprinkle some of the blood with his finger seven times.
15 "Then he shall 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 bull, and sprinkle it on the mercy seat, and before the mercy seat: 16 and he shall make atonement for the Holy Place, because of the uncleanness of the children of Israel, and because of their transgressions, even all their sins; and so he shall do for the Tent of Meeting, that dwells with them in the midst of their uncleanness. 17 There shall be no one in the Tent of Meeting when he enters to make atonement in the Holy Place, until he comes out, and has made atonement for himself and for his household, and for all the assembly of Israel. 18 "He shall go out to the altar that is before the LORD and make atonement for it, and shall take some of the bull's blood, and some of the goat's blood, and put it around on the horns of the altar. 19 He shall sprinkle some of the blood on it with his finger seven times, and cleanse it, and make it holy from the uncleanness of the children of Israel.
