Exodus 36:31-34

31He also made five crossbars of acacia wood for the frames on one side of the tabernacle, 32five for those on the other side, and five for those on the rear side of the tabernacle, to the west.

33He made the central crossbar to run through the center of the frames, from one end to the other. 34And he overlaid the frames with gold and made gold rings to hold the crossbars. He also overlaid the crossbars with gold.
