Exodus 26:26

You shall make two boards for the corners of the tabernacle in the far side.

They shall be double beneath, and in the same way they shall be whole to its top to one ring: thus shall it be for them both; they shall be for the two corners.

There shall be eight boards, and their sockets of silver, sixteen sockets; two sockets under one board, and two sockets under another board.

and five bars for the boards of the other side of the tabernacle, and five bars for the boards of the side of the tabernacle, for the far side westward.

The middle bar in the middle of the boards shall pass through from end to end.

You shall overlay the boards with gold, and make their rings of gold for places for the bars. You shall overlay the bars with gold.
