If Jesus is the High Priest, He needs a Temple to minister. There was the earthly Tabernacle which was constructed according to the pattern God showed Moses (Exodus 25:8-9). The Hebrews epistle writer summarizes the earth tabernacle.
My translation and notes on Hebrews 9:1-10
Hebrews Chapter 9
The Earthly Tabernacle
1 Now truly, the first [covenant] had regulations for worship and an earthly holy place.
2 For a tent was completely prepared. The outer part [had] in it the candlestick, the table, and the showbread. This is the Holy Place.
3 Behind the second curtain of the tent is [the place] called the Holy of Holies,
4 Having the golden alter of incense and the ark of the covenant, which was totally covered with gold [containing] the golden jar that held manna, Aaron’s rod that budded, and the tablets of the covenant.
5 Over it [were] the cherubim of glory whose shadow covered the mercy seat concerning which we cannot now speak in detail.
6 Now after these things were completely prepared, the priests always went into the outer tent doing the service [of God].
7 But only the high priest [goes] into the inner tent and then only once a year, and never without blood which he brought for himself and for the errors of the people.
[It is evident that the writer and the readers know the Tabernacle and its ministry well. Knowing all these things, we now follow the writer revealing the superiority of Jesus as High Priest and the heavenly Tabernacle].
8 The Holy Spirit making it evident that while the first tent was still standing the way into the Holy of Holies was not yet open.
9 This was a symbol for the present time, in which both gifts and sacrifices that are offered cannot make the conscience of the one who serves perfect,
[What we have and bring are not good enough. No matter how great the gift or sacrifice, it is not enough to atone for sins, make the conscience clear, and to restore fellowship with God. It is only a symbol because Jesus the High Priest is superior].
10 Since [they dealt with] only foods, drinks, various washings, and regulations [for the] body imposed [on them] until the time things would be straightened out.
[This is the reason—they only took care of violations of foods, etc. instead of the need to take care of the sin nature. Barclay (DAILY STUDY BIBLE) adds: Every year this ceremony had to be gone through again. Everyone but the High Priest was barred from the presence and even he entered in terror. The cleansing was a purely external one by baths of water. The sacrifice was that of bulls and goats and animal blood. The whole thing failed because such things cannot atone for sin. In it all the writer to the Hebrews sees a pale copy of the reality, a ghostly pattern of the one true sacrifice—the sacrifice of Christ. It was a noble ritual, a thing of dignity and beauty; but it was only an unavailing shadow. The only priest and the only sacrifice which can open the way to God for all men is Jesus Christ].
