Leviticus 16:15–20

^15*After that, he shall kill the goat for the sin offering for the people, bring its blood into the Most Holy Place, and sprinkle it on the lid and then in front of the Covenant Box, as he did with the bull’s blood. ¹⁶In this way he will perform the ritual to purify the Most Holy Place from the uncleanness of the people of Israel and from all their sins. He must do this to the Tent, because it stands in the middle of the camp, which is ritually unclean. ¹⁷From the time Aaron enters the Most Holy Place to perform the ritual of purification until he comes out, there must be no one in the Tent. When he has performed the ritual for himself, his family, and the whole community, ¹⁸he must then go out to the altar for burnt offerings and purify it. He must take some of the bull’s blood and some of the goat’s blood and put it all over the projections at the corners of the altar. ¹⁹With his finger he must sprinkle some of the blood on the altar seven times. In this way he is to purify it from the sins of the people of Israel and make it holy.

The Scapegoat

²⁰When Aaron has finished performing the ritual to purify the Most Holy Place, the rest of the Tent of the Lord’s presence, and the altar, he shall present to the Lord the live goat chosen for Azazel.^g
