Exodus 36:22-24

Amplified Bible, Classic Edition

²² Each board had two tenons (projections) to fit into a mortise to form a clutch; he did this for all the boards of the tabernacle.

²³ And he made thus the boards [for frames] for the tabernacle: twenty boards for the south side,

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