Hebrews 9:7-10

And the high priest was permitted to enter into the Holiest Sanctuary of All only once a year and he could never enter without first offering sacrificial blood for both his own sins and for the sins of the people. Now the Holy Spirit uses the symbols of this pattern of worship to reveal that the perfect way of holiness had not yet been unveiled. For as long as the tabernacle stood it was an illustration that pointed to our present time of fulfillment, demonstrating that offerings and animal sacrifices had failed to perfectly cleanse the conscience of the worshiper. For this old pattern of worship was a matter of external rules and rituals concerning food and drink and ceremonial washings which was imposed upon us until the appointed time of heart-restoration had arrived.
