Exodus 36:31-38

Then he made crossbars of acacia wood to link the frames, five crossbars for the north side of the Tabernacle and five for the south side. He also made five crossbars for the rear of the Tabernacle, which faced west. He made the middle crossbar to attach halfway up the frames; it ran all the way from one end of the Tabernacle to the other. He overlaid the frames with gold and made gold rings to hold the crossbars. Then he overlaid the crossbars with gold as well. For the inside of the Tabernacle, Bezalel made a special curtain of finely woven linen. He decorated it with blue, purple, and scarlet thread and with skillfully embroidered cherubim. For the curtain, he made four posts of acacia wood and four gold hooks. He overlaid the posts with gold and set them in four silver bases. Then he made another curtain for the entrance to the sacred tent. He made it of finely woven linen and embroidered it with exquisite designs using blue, purple, and scarlet thread. This curtain was hung on gold hooks attached to five posts. The posts with their decorated tops and hooks were overlaid with gold, and the five bases were cast from bronze.
