Exodus 36:30

²⁸  And two boards made he for the corners of the tabernacle in the two sides.

²⁹  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.

³⁰  And there were eight boards; and their sockets were sixteen sockets of silver, under every board two sockets.

³¹  And he made bars of shittim wood; five for the boards of the one side of the tabernacle,

³²  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.
