Hebrews 9 presents a detailed contrast between the Old Covenant sanctuary (the tabernacle) and the New Covenant heavenly sanctuary where Jesus Christ now ministers. This contrast makes it clear that the New Covenant sanctuary is superior.
This section of Hebrews reminds readers that the regulations and practices in the tabernacle were ordained of God. If there was any inferiority in the tabernacle service, it was not because God had not established the ritual. While the Old Covenant was in force, the ministry of the priests was ordained of God and perfectly proper.
It was an earthly sanctuary, meaning made by human hands and out of earthly material. God gave spiritual wisdom and skill to Bezalel and Oholiab to do the intricate work of making the various parts of the tabernacle and its furnishings (Ex. 35–36).
The writer listed the various parts and furnishings of the tabernacle because each of these carried a spiritual meaning. They were “patterns of things in the heavens” (Heb. 9:23).
https://seekingourgod.com/hebrews-91-5-the-furniture-of-the-tabernacle/The Christian is a citizen of two worlds, the earthly and the heavenly. We must render to Caesar (or the government) the things that are Caesar’s and to God the things that are God’s (Matt. 22:21). Because a Christian is a citizen of two worlds, we must learn how to walk by faith in a world that is governed by sight. Like Moses, a believer must see the invisible if they are to overcome the pull of the world (Heb. 11:24–27). A practical person says, “Seeing is believing!” But the person of faith replies, “Believing is seeing!”
This principle of faith must apply to our relationship to the heavenly sanctuary. We have never seen this sanctuary. Yet we believe what the Bible tells us about it. We realize that God is not worshiped today in temples made with hands (Acts 7:46–50). There is no special place on earth where God dwells (cf. Isa. 57:15; 66:1–2; John 4:19–24). We may call a local church building a “house of God,” but we know that God does not live there. The building is dedicated to God and His service, but it is not His dwelling place.
With regard to the “aging” First Covenant, the writer wished to discuss that covenant’s regulations for worship and its earthly sanctuary. These the author highlighted in order to contrast them with the superior features of the New Covenant ministry. How “earthly” (kosmikon, v. 1), or mundane, that first sanctuary was, the author emphasized by reviewing the material objects associated with it. All these had typological value, but the author could not discuss these things in detail at the time (v. 5). The author confined themselves to the chief features of the comparison they wished to make.
The discussion regarding the sanctuary prepares you for consideration of a sacrifice. So the writer has got to talk about the furniture. Then the writer will keep moving on to the sacrifice.
