Exodus 36:28-32

And two boards made he for the corners of the tabernacle in the two sides.

And they were coupled beneath, and coupled together at the head thereof, to one ring: thus he did to both of them in both the corners.

And there were eight boards; and their sockets were sixteen sockets of silver, under every board two sockets.

And he made bars of shittim wood; five for the boards of the 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 sides westward.
