Exodus 36:31

He made two boards for the corners of the tabernacle in the far part.

They were double beneath, and in the same way they were all the way to its top to one ring. He did this to both of them in the two corners.

There were eight boards and their sockets of silver, sixteen sockets—under every board two sockets.

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

He made the middle bar to pass through in the middle of the boards from the one end to the other.

He overlaid the boards with gold, and made their rings of gold as places for the bars, and overlaid the bars with gold.
