26:17Two tenons shall there be in one board, set in order one against another: thus shalt thou make for all the boards of the tabernacle.

26:19And thou shalt 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.

36:22One board had two tenons, equally distant one from another: thus did he make for all the boards of the tabernacle.

36:23And he made boards for the tabernacle; twenty boards for the south side southward:

36:24And forty sockets of silver he made under the twenty boards; two sockets under one board for his two tenons, and two sockets under another board for his two tenons.
