Leviticus 16:11-19

“Then Aaron will offer the bull as a sin offering for himself, to remove the sins from him and his family so they will belong to the LORD; he will kill the bull for the sin offering for himself. Then he must take a pan full of burning coals from the altar before the LORD and two handfuls of sweet incense that has been ground into powder. He must bring it into the room behind the curtain. He must put the incense on the fire before the LORD so that the cloud of incense will cover the lid on the Ark. Then when Aaron comes in, he will not die. Also, he must take some of the blood from the bull and sprinkle it with his finger on the front of the lid; with his finger he will sprinkle the blood seven times in front of the lid. “Then Aaron must kill the goat of the sin offering for the people and bring its blood into the room behind the curtain. He must do with the goat’s blood as he did with the bull’s blood, sprinkling it on the lid and in front of the lid. Because the people of Israel have been unclean, Aaron will perform the acts to make the Most Holy Place ready for service to the LORD. Then it will be clean from the sins and crimes of the Israelites. He must also do this for the Meeting Tent, because it stays in the middle of unclean people. When Aaron makes the Most Holy Place ready for service to the LORD, no one is allowed in the Meeting Tent until he comes out. So Aaron will perform the acts to remove sins from himself, his family, and all the people of Israel, so they will belong to the LORD. Afterward he will go out to the altar that is before the LORD and will make it ready for service to the LORD. Aaron will take some of the bull’s blood and some of the goat’s blood and put it on the corners of the altar on all sides. Then, with his finger, he will sprinkle some of the blood on the altar seven times to make the altar holy for the LORD and clean from all the sins of the Israelites.
