Leviticus 16:3; Leviticus 16:15; Leviticus 16:33; Leviticus 16:34

3 “This is how Aaron is to enter the Most Holy Place: He must first bring a young bull for a sin offering and a ram for a burnt offering.

15 “He shall then slaughter the goat for the sin offering for the people and take its blood behind the curtain and do with it as he did with the bull’s blood: He shall sprinkle it on the atonement cover and in front of it.

33 and make atonement for the Most Holy Place, for the tent of meeting and the altar, and for the priests and all the members of the community.

34 “This is to be a lasting ordinance for you: Atonement is to be made once a year for all the sins of the Israelites.” And it was done, as the LORD commanded Moses.
