Leviticus 16:11-14

After these things are duly celebrated, he shall offer the calf: and praying for himself and for his own house, he shall immolate it: And taking the censer, which he hath filled with the burning coals of the altar, and taking up with his hand the compounded perfume for incense, he shall go in within the veil into the holy place: That when the perfumes are put upon the fire, the cloud and vapour thereof may cover the oracle, which is over the testimony, and he may not die. He shall take also of the blood of the calf, and sprinkle with his finger seven times towards the propitiatory to the east.
