The crossbar

I believe the Tabernacle is interesting. The crossbars strengthen the frames on the north, south, and west sides of the courtyards. The gold rings on the sides of the chest to carry the ark. A curtain was to divide the tabernacle into two rooms, the Holy place and the most holy place. The Most Holy Place formed a perfect square 15 feet by 15 feet by 15 feet. Enclosed with linen curtains embroidered with cherubim . It contained the ark of the Testimony, it represented God's throne room. The Holy Place represented his royal guest chamber where his people symbolically came before him in the bread of the  Presence. The light from the lamp-stand and the incense from the altar of incense. Inside the tabernacle, gold was the metal of choice; On the outside beginning with the bases of the outer curtain. In this area, the metal of choice was bronze. The furnishings near to the place of God's dwelling were made of gold; those farther away were made of bronze. The bases that supported the frames of the tabernacle and the four posts holding the dividing curtain were made of silver.

Exodus 26:26-37

 

²⁶ “Also make crossbars of acacia wood: five for the frames on one side of the tabernacle, ²⁷ five for those on the other side, and five for the frames on the west, at the far end of the tabernacle. ²⁸ The center crossbar is to extend from end to end at the middle of the frames. ²⁹ Overlay the frames with gold and make gold rings to hold the crossbars. Also overlay the crossbars with gold.
³⁰ “Set up the tabernacle according to the plan shown you on the mountain.
³¹ “Make a curtain of blue, purple and scarlet yarn and finely twisted linen, with cherubim woven into it by a skilled worker. ³² Hang it with gold hooks on four posts of acacia wood overlaid with gold and standing on four silver bases. ³³ Hang the curtain from the clasps and place the ark of the covenant law behind the curtain. The curtain will separate the Holy Place from the Most Holy Place. ³⁴ Put the atonement cover on the ark of the covenant law in the Most Holy Place. ³⁵ Place the table outside the curtain on the north side of the tabernacle and put the lampstand opposite it on the south side.
³⁶ “For the entrance to the tent make a curtain of blue, purple and scarlet yarn and finely twisted linen—the work of an embroiderer. ³⁷ Make gold hooks for this curtain and five posts of acacia wood overlaid with gold. And cast five bronze bases for them.
