Exodus 36:20-30

20And he made the boards for the tabernacle of acacia-wood, standing up;

21ten cubits the length of the boards, and one cubit and a half the breadth of one board;

22two tenons in one board, connected one with the other: thus did he make for all the boards of the tabernacle.

23And he made the boards for the tabernacle: twenty boards for the south side southward;

24and he made forty bases of silver under the twenty boards, two bases under one board, for its two tenons, and two bases under another board for its two tenons.

25And for the other side of the tabernacle, on the side toward the north, he made twenty boards,

26and their forty bases of silver, two bases under one board, and two bases under another board.

27And at the rear of the tabernacle, westward, he made six boards;

28and he made two boards for the corners of the tabernacle at the rear;

29and they were joined beneath, and were coupled together at the top thereof into one ring: thus he did to both of them in both the corners;

30and there were eight boards, and their silver bases: sixteen bases, under every board two bases.
