Exodus 36:31-34

31Then he made crossbars of acacia wood to link the frames, five crossbars for the north side of the Tabernacle

32and five for the south side. He also made five crossbars for the rear of the Tabernacle, which faced west.

33He made the middle crossbar to attach halfway up the frames; it ran all the way from one end of the Tabernacle to the other.

34He overlaid the frames with gold and made gold rings to hold the crossbars. Then he overlaid the crossbars with gold as well.
