Exodus 26:25

²³  And two boards shalt thou make for the corners of the tabernacle in the two sides.

²⁴  And they shall be coupled together beneath, and they shall be coupled together above the head of it unto one ring: thus shall it be for them both; they shall be for the two corners.

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.
