Exodus 26:26-30

And thou shalt make bars of acacia wood: five for the boards of the one side of the tabernacle, and five bars for the boards of the other side of the tabernacle, and five bars for the boards of the side of the tabernacle, for the hinder part westward. And the middle bar in the midst of the boards shall pass through from end to end. And thou shalt overlay the boards with gold, and make their rings of gold for places for the bars: and thou shalt overlay the bars with gold. And thou shalt rear up the tabernacle according to the fashion thereof which hath been showed thee in the mount.
