Hebrews 9:23-24

That is why the Tabernacle and everything in it, which were copies of things in heaven, had to be purified by the blood of animals. But the real things in heaven had to be purified with far better sacrifices than the blood of animals. For Christ did not enter into a holy place made with human hands, which was only a copy of the true one in heaven. He entered into heaven itself to appear now before God on our behalf.
