What we have here is a description of the tabernacle constructed by Moses in the wilderness. It is called the first tabernacle, to distinguish it from the heavenly tabernacle, the true tabernacle (Hebrews 8:2).
How we value truth, the truth of God! What would we know about God without revelation? What can human imagination tell us? We see how human imagination goes wrong in these things. You ask anybody who knows little about Christian teaching, how do you approach God and their immediate assumption is that well, you approach God, presumably by living a better life, by giving away money, by doing various good works. Now the Bible has taught us that that is as wrong as it could possibly be. Because of our sinfulness and his holiness the only approach to God is by receiving a free salvation purchased for us by Christ. You see how we would go wrong without revelation, and that great candelabra represented the revelation that God gives to this world.
