Hebrews 9:3-8

Hebrews 9:3-8. And after the second veil, the tabernacle which is called the Holiest of All; which had the golden censer, and the ark of the covenant overlaid round about with gold, wherein was the golden pot that had manna, and Aaron’s rod that budded, and the tables of the covenant; and over it the cherubims of glory shadowing the mercyseat; of which we cannot now speak particularly. Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God. But into the Second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people: the Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:

Notice especially those words, "Not without blood." There could be no approach to God under the old dispensation without the shedding of blood, and there is no access to the Lord now without the precious blood of Christ.
