Leviticus 16:11-14

“And Aaron shall present the sin offering’s bull, which is for himself, and so he shall make atonement for himself and for his family; then he shall slaughter the sin offering’s bull, which is for himself. And he shall take a censer full of burning charcoal from upon the altar from before Yahweh and two handfuls of incense of powdered fragrant perfumes, and he shall bring it from behind the curtain, and he shall put the incense on the fire before Yahweh so that the cloud of incense might cover the atonement cover, which is on the covenant text, so that he might not die. And he shall take some of the bull’s blood, and he shall spatter it with his finger on the atonement cover’s surface on the eastern side, and before the atonement cover he shall spatter some of the blood with his finger seven times.
