Hebrews 9:3-8

3Behind the second curtain was a room called the Most Holy Place, 4which had the golden altar of incense and the gold-covered ark of the covenant. This ark contained the gold jar of manna, Aaron’s staff that had budded, and the stone tablets of the covenant. 5Above the ark were the cherubim of the Glory, overshadowing the atonement cover. But we cannot discuss these things in detail now. 6When everything had been arranged like this, the priests entered regularly into the outer room to carry on their ministry. 7But only the high priest entered the inner room, and that only once a year, and never without blood, which he offered for himself and for the sins the people had committed in ignorance. 8The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still functioning.
