Exodus 26:26-29

26And thou shalt make bars of acacia-wood; five for the boards of the one side of the tabernacle,

27and five bars for the boards of the other side of the tabernacle, and five bars for the boards of the side of the tabernacle at the rear westward;

28and the middle bar in the midst of the boards reaching from one end to the other.

29And thou shalt overlay the boards with gold, and make [of] gold their rings, the receptacles of the bars, and shalt overlay the bars with gold.
