Then shall he kill the goat of the sin offering that is for [the sins of] the people and bring its blood within the veil [into the Holy of Holies] and do with that blood as he did with the blood of the bull, and sprinkle it on the mercy seat and before the mercy seat. Thus he shall make atonement for the Holy Place because of the uncleanness of the Israelites and because of their transgressions, even all their sins; and so shall he do for the Tent of Meeting, that remains among them in the midst of their uncleanness.
