Exodus 26:26-29

“Make crossbars of acacia wood to link the frames, five crossbars for the north side of the Tabernacle and five for the south side. Also make five crossbars for the rear of the Tabernacle, which will face west. The middle crossbar, attached halfway up the frames, will run all the way from one end of the Tabernacle to the other. Overlay the frames with gold, and make gold rings to hold the crossbars. Overlay the crossbars with gold as well.
