Exodus 36:20-24 ▼

20 Bezalel made boards of acacia wood for the upright framework of the tabernacle.

21 Each board was ten cubits long and one and a half cubits wide.

22 Each board had two tenons (dovetails), fitted to one another; he did this for all the boards of the tabernacle.

23 And [this is how] he made the boards [for frames] for the tabernacle: twenty boards for the south side;

24 and he made under the twenty boards forty silver sockets; two sockets under one board for its two tenons (dovetails), and two sockets under another board for its two tenons.
