Leviticus 16:15-17

New Revised Standard Version Catholic Edition

¹⁵ He shall slaughter the goat of the sin offering that is for the people and bring its blood inside the curtain, and do with its blood as he did with the blood of the bull, sprinkling it upon the mercy seat^[a] and before the mercy seat.^{[b] 16} Thus he shall make atonement for the sanctuary, because of the uncleannesses of the people of Israel, and because of their transgressions, all their sins; and so he shall do for the tent of meeting, which remains with them in the midst of their uncleannesses. ¹⁷ No one shall be in the tent of meeting from the time he enters to make atonement in the sanctuary until he comes out and has made atonement for himself and for his house and for all the assembly of Israel.
