And you shall make the boards for the tabernacle, twenty boards on the south side southward.
Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
And you shall make boards for the tabernacle of shittim wood standing up.
Two tenons shall there be in one board, set in order one against another: thus shall you make for all the boards of the tabernacle.
And you shall make forty sockets of silver under the twenty boards; two sockets under one board for his two tenons, and two sockets under another board for his two tenons.
