Exodus 26:27

²⁵  And they shall be eight boards, and their sockets of silver, sixteen sockets; two sockets under one board, and two sockets under another board.

²⁶  And thou shalt make bars of shittim wood; five for the boards of the one side of the tabernacle,

²⁷  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 two sides westward.

²⁸  And the middle bar in the midst of the boards shall reach from end to end.

²⁹  And thou shalt overlay the boards with gold, and make their rings of gold for places for the bars: and thou shalt overlay the bars with gold.
