Leviticus 16:3-10

3“When Aaron enters the sanctuary area, he must follow these instructions fully. He must bring a young bull for a sin offering and a ram for a burnt offering.

4He must put on his linen tunic and the linen undergarments worn next to his body. He must tie the linen sash around his waist and put the linen turban on his head. These are sacred garments, so he must bathe himself in water before he puts them on.

5Aaron must take from the community of Israel two male goats for a sin offering and a ram for a burnt offering.

6“Aaron will present his own bull as a sin offering to purify himself and his family, making them right with the Lord.

7Then he must take the two male goats and present them to the Lord at the entrance of the Tabernacle.

8He is to cast sacred lots to determine which goat will be reserved as an offering to the Lord and which will carry the sins of the people to the wilderness of Azazel.

9Aaron will then present as a sin offering the goat chosen by lot for the Lord.

10The other goat, the scapegoat chosen by lot to be sent away, will be kept alive, standing before the Lord. When it is sent away to Azazel in the wilderness, the people will be purified and made right with the Lord.
