What does 2 Chronicles 3-4 really mean?

³ Then Solomon began to build the house of the Lord in Jerusalem on Mount Moriah, where the Lord had appeared to David his father, at the place that David had appointed, on the threshing floor of Ornan the Jebusite.
² He began to build in the second day of the second month in the fourth year of his reign.
³ These are Solomon’s measurements for building the house of God: the length, in cubits of the old standard, was sixty cubits, and the breadth twenty cubits.
⁴ The vestibule in front of the nave of the house was twenty cubits long, equal to the width of the house, and its height was 120 cubits. He overlaid it on the inside with pure gold.
⁵ The nave he lined with cypress and covered it with fine gold and made palms and chains on it.
⁶ He adorned the house with settings of precious stones. The gold was gold of Parvaim.
⁷ He overlaid the house with gold, its beams, its thresholds, and its walls and its doors; and he carved cherubim on the walls.
⁸ The Most Holy Place was twenty cubits long, corresponding to the width of the house, and twenty cubits wide.
⁹ The weight of the nails was fifty shekels of gold. He also overlaid the upper chambers with gold.
¹⁰ And he overlaid the whole house with gold, until all the house was finished.
¹¹ The wings of the cherubim together extended twenty cubits: one wing of the one, of five cubits, touched the wall of the house, and its other wing, of five cubits, touched the wing of the other cherub.
¹² The two doors were of olive wood, and he carved on them carvings of cherubim, palm trees, and open flowers, and overlaid them with gold; and he spread gold on the cherubim and on the palm trees.
¹³ The wings of these cherubim extended twenty cubits. The cherubim stood on their feet, facing the main hall.
¹⁴ He made the veil of blue and purple and crimson fabrics and fine linen, and he worked cherubim on it.
¹⁵ In front of the house he made two pillars thirty-five cubits high, with a capital of five cubits on the top of each.
¹⁶ He made chains like a necklace and put them on the tops of the pillars, and he made a hundred pomegranates and put them on the chains.
¹⁷ He set up the pillars in front of the temple, one on the south, the other on the north; that on the south he called Jachin, and that on the north Boaz.
¹ He made an altar of bronze, twenty cubits long and twenty cubits wide and ten cubits high.
² And he cast a round molding, half a cubit high, around the top of it.
³ Now figures like oxen were under it, and all around it. And the second row of oxen was below the first row.
⁴ He also made a sea of cast metal ten cubits from brim to brim, circular in form, and five cubits high, and a line of thirty cubits measured its circumference.
⁵ It was a handbreadth thick, and its brim was made like the brim of a cup, like the flower of a lily. It held 3,000 baths.
⁶ He also made ten basins in which to wash, and set five on the south side, and five on the north side, to rinse in them things for the burnt offering. They were made of cast metal.
⁷ And he made ten golden lampstands as prescribed by the law and set them in the temple, five on the south side and five on the north.
⁸ He also made ten tables and placed them in the temple, five on the south side and five on the north.
⁹ Then he made the court of the priests and the great court and doors for the court and overlaid their doors with bronze.
¹⁰ He set the sea at the southeast corner of the house, east of the south.
¹¹ Huram also made the pots, the shovels, and the basins. So Huram finished the work that he did for King Solomon on the house of God:
¹² the two pillars, the bowls, and the two capitals on the top of the pillars; and the two latticeworks to cover the two bowls of the capitals that were on the top of the pillars;
¹³ and the four hundred pomegranates for the two lattices, two rows of pomegranates for each latticework to cover the two bowls of the capitals that were on the pillars.
¹⁴ He made the stands also, and the basins on the stands,
¹⁵ the pots, the shovels, and the basins. All these vessels in the house of the Lord which Hiram made for King Solomon were of burnished bronze.
¹⁶ The pots, the shovels, and the basins, all these vessels that Hiram made for King Solomon for the house of the Lord were of burnished bronze.
¹⁷ In the plain of the Jordan the king cast them, in the clay ground between Succoth and Zeredah.
¹⁸ So Solomon made all these vessels in great quantities, for the weight of the bronze was not sought.
¹⁹ Solomon also made all the vessels that were in the house of God, the golden altar, the tables for the bread of the Presence,
²⁰ the lampstands and their lamps of pure gold to burn before the inner sanctuary, as prescribed;
²¹ the flowers, the lamps, and the tongs, of purest gold.
²² the snuffers, basins, dishes for incense, and fire pans, of pure gold, and the sockets of the temple for the inner doors to the Most Holy Place and for the doors of the nave of the temple were of gold.
