Leviticus 16:11-14, 18-19

“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.

“Then he will come out to the Altar that is before GOD and make atonement for it. He will take some of the bull’s blood and some of the goat’s blood and smear it all around the four horns of the Altar. With his finger he will sprinkle some of the blood on it seven times to purify and consecrate it from the uncleannesses of the Israelites.
