Leviticus 16:11-17

“Aaron will present his bull for an Absolution-Offering to make atonement for himself and his household. He will slaughter his bull for the Absolution-Offering. He will take a censer full of burning coals from the Altar before GOD and two handfuls of finely ground aromatic incense and bring them inside the curtain and put the incense on the fire before GOD; the smoke of the incense will cover the Atonement-Cover which is over The Testimony so that he doesn’t die. He will take some of the bull’s blood and sprinkle it with his finger on the front of the Atonement-Cover, then sprinkle the blood before the Atonement-Cover seven times. “Next he will slaughter the goat designated as the Absolution-Offering for the people and bring the blood inside the curtain. He will repeat what he does with the bull’s blood, sprinkling it on and before the Atonement-Cover. In this way he will make atonement for the Holy of Holies because of the uncleannesses of the Israelites, their acts of rebellion, and all their other sins. He will do the same thing for the Tent of Meeting which dwells among the people in the midst of their uncleanness. There is to be no one in the Tent of Meeting from the time Aaron goes in to make atonement in the Holy of Holies until he comes out, having made atonement for himself, his household, and the whole community of Israel.
