Leviticus 16:3-13

³These are the instructions as to how Aaron is to enter the sanctuary. He is to come with a young bull for a sin offering and a ram for a burnt offering.

⁴He is to be wearing the holy linen tunic, with linen underwear. He has to tie a linen sash around him and put on the linen turban. These are holy clothes. He must wash himself with water before he puts them on.

⁵From the people of Israel he is to bring two male goats for a sin offering, and a ram for a burnt offering.

⁶Aaron will present the bull as his own sin offering to make himself and his household right.

⁷Then he will bring the two goats and present them before the Lord at the entrance to the Tent of Meeting.

⁸Aaron will casts lots to choose between the goats, one for the Lord and the other for the scapegoat.

⁹He will present the goat that was chosen by lot for the Lord and sacrifice it as a sin offering.

¹⁰The goat chosen by lot as the scapegoat is to be presented alive before the Lord to make things right by sending it away into the wilderness as the scapegoat.

¹¹Aaron is to present the bull for his sin offering to make things right for himself and his household by killing the bull as his own sin offering.

¹²Then he will fill up a incense burner with burning coals from the altar that is before the Lord, and with his hands full of finely-ground sweet-smelling incense, take them behind the veil.

¹³In the presence of the Lord he will put the incense on the burning coals, and the smoke from the incense will cover the atonement cover above the Testimony, so that he will not die.
