Exodus 26:22-25

22And for the rear of the tabernacle westward thou shalt make six boards.

23And two boards shalt thou make for the corners of the tabernacle at the rear;

24and they shall be joined beneath, and together shall be united at the top thereof to one ring: thus shall it be for them both; they shall be for the two corners.

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