Exodus 36:20-34

Then he made the boards for the tabernacle of acacia wood, standing upright. Ten cubits was the length of each board and one and a half cubits the width of each board. There were two tenons for each board, fitted to one another; thus he did for all the boards of the tabernacle. He made the boards for the tabernacle: twenty boards for the south side; and he made forty sockets of silver under the twenty boards; two sockets under one board for its two tenons and two sockets under another board for its two tenons. Then for the second side of the tabernacle, on the north side, he made twenty boards, and their forty sockets of silver; two sockets under one board and two sockets under another board. For the rear of the tabernacle, to the west, he made six boards. He made two boards for the corners of the tabernacle at the rear. They were double beneath, and together they were complete to its top to the first ring; thus he did with both of them for the two corners. There were eight boards with their sockets of silver, sixteen sockets, two under every board. Then he made bars of acacia wood, five for the boards of 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 tabernacle for the rear side to the west. He made the middle bar to pass through in the center of the boards from end to end. He overlaid the boards with gold and made their rings of gold as holders for the bars, and overlaid the bars with gold.
