Hebrews 9:6-8

Living Bible

⁶ Well, when all was ready, the priests went in and out of the first room whenever they wanted to, doing their work. ⁷ But only the high priest went into the inner room, and then only once a year, all alone, and always with blood that he sprinkled on the mercy seat as an offering to God to cover his own mistakes and sins and the mistakes and sins of all the people.

⁸ And the Holy Spirit uses all this to point out to us that under the old system the common people could not go into the Holy of Holies as long as the outer room and the entire system it represents were still in use.
