Exodus 36:20-30

20He also made the framework of boards for the Tabernacle from acacia wood, standing upright.

21The length of a board was ten cubits, the width was a cubit and a half.

22Each board had two supports, joined one to another. He did this for all the boards of the Tabernacle.

23So he built the boards for the Tabernacle, 20 boards from the south side southward.

24And he made 40 silver bases under the 20 boards, two bases under one board for its two supports, and two bases under another board for its two supports.

25Also for the second side of the Tabernacle, on the north side, he made 20 boards,

26along with their 40 silver bases, two under one board and two under the next.

27For the back part of the Tabernacle westward he made six boards.

28He also made two boards for the corners of the Tabernacle in the back,

29so that they could be doubled underneath, and in same way to be fixed to the top, at the first ring. He did this for both of them at the two corners.

30So there were eight boards, along with their silver bases, 16 in all, two under each board.
