"Paul calls the Sanctuary of the first covenant, "which was a figure for the time then present, in which were offered both gifts and sacricifices;" Hebrews 9:9.
"But Christ being come an High Priest of good things to come by a greater and more perfect tabernacle, not made with hands;" verse 11.
The priests entered the "figures" or "patterns of the true", which true are the "heavenly places themselves", into which Christ entered when He entered "heaven itself"; verses 23, 24. When He ascended to the right hand of the Father, "in the heavens", He became "A Minister of the Sanctuary (or Hagion, Holies) and of the true tabernacle, which the Lord pitched and not man;" Hebrews 8:1,2. That is the Sanctuary of the "better (the new) covenant;" verse 6.
---The Sanctuary to be cleansed at the end of 2300 days is also the Sanctuary of the new covenant, for the vision of the treading down and cleansing, is after the crucifixion. We see that the Sanctuary of the new covenant is not on earth, but in heaven."
