leviticus
16Tell your brother Aaron that he is not to come at will into the Shrine behind the curtain, in front of the cover that is upon the ark, lest he die; for I appear in the cloud over the cover.16:3. Thus only shall Aaron enter the Shrine: with a bull of the herd for a sin offering and a ram for a burnt offering.16:4. He shall be dressed in a sacral linen tunic, with linen breeches next to his flesh, and be girt with a linen sash, and he shall wear a linen turban. They are sacral vestments; he shall bathe his body in water and then put them on.16:5. And from the Israelite community he shall take two he-goats for a sin offering and a ram for a burnt offering.16:6. Aaron is to offer his own bull of sin offering, to make expiation for himself and for his household.16:7. Aaron shall take the two he-goats and let them stand before the LORD at the entrance of the Tent of Meeting;16:8. and he shall place lots upon the two goats, one marked for the LORD and the other marked for Azazel.16:9. Aaron shall bring forward the goat designated by lot for the LORD, which he is to offer as a sin offering;16:10. while the goat designated by lot for Azazel shall be left standing alive before the LORD, to make expiation with it and to send it off to the wilderness for Azazel.16:11. Aaron shall then offer his bull of sin offering, to make expiation for himself and his household.
He shall slaughter his bull of sin offering,16:12. and he shall take a panful of glowing coals scooped from the altar before the LORD, and two handfuls of finely ground aromatic incense, and bring this behind the curtain.16:13. He shall put the incense on the fire before the LORD, so that the cloud from the incense screens the cover that is over [the Ark of] the Pact, lest he die.16:14. He shall take some of the blood of the bull and sprinkle it with his finger over the cover on the east side; and in front of the cover he shall sprinkle some of the blood with his finger seven times.16:
15. He shall then slaughter the people’s goat of sin offering, bring its blood behind the curtain, and do with its blood as he has done with the blood of the bull: he shall sprinkle it over the cover and in front of the cover.16:16.
