Leviticus 16:3-13

³With this shall Aaron come into the holy place: with a young bullock for a sin-offering, and a ram for a burnt-offering.

⁴A holy linen coat shall be put on, and linen breeches shall he have upon his flesh, and with a linen girdle shall he gird himself, and a linen mitre shall he bind on his head; these are holy garments; therefore shall he wash his flesh in water, and then put them on.

⁵And from the congregation of the children of Israel shall he take two goats for a sin-offering, and one ram for a burnt-offering.

⁶And Aaron shall bring near the bullock of the sin-offering, which is for himself, and make an atonement for himself, and for his house.

⁷And he shall take the two goats, and place them before the Lord at the door of the tabernacle of the congregation.

⁸And Aaron shall put lots upon the two goats; one lot “for the Lord,” and the other lot “for 'Azazel.”

⁹And Aaron shall bring near the goat upon which fell the lot “for the Lord,” and offer him for a sin-offering.

¹⁰But the goat on which fell the lot “for 'Azazel,” shall be placed alive before the Lord, to make an atonement with him, by sending him away to 'Azazel into the wilderness.

¹¹And Aaron shall bring near the bullock of the sin-offering, which is for himself, and he shall make an atonement for himself, and for his house; and he shall kill the bullock of the sin-offering which is for himself.

¹²And he shall take a censer full of burning coals of fire from off the altar before the Lord, and both his hands full of incense of spices, pounded fine, and bring it within the vail;

¹³And he shall put the incense upon the fire, before the Lord; that the cloud of the incense may envelop the mercy-seat that is upon the testimony, that he die not.
