Exodus 36:31-34

31And he made bars of acacia wood: five for the boards on one side of the tabernacle,

32five bars for the boards on the other side of the tabernacle, and five bars for the boards of the tabernacle on the far side westward.

33And he made the middle bar to pass through the boards from one end to the other.

34He overlaid the boards with gold, made their rings of gold to be holders for the bars, and overlaid the bars with gold.
