Exodus 26:19

and forty bases of silver you shall make under the twenty frames, two bases under one frame for its two tenons, and two bases under the next frame for its two tenons;

and make forty silver bases to go under them—two bases for each frame, one under each projection.

Also make forty silver bases—two bases under each frame, with the pegs fitting securely into the bases.

And you will make forty silver bases under the twenty frames, with two bases under the one frame for its two pegs and two bases under the next frame for its two pegs.

And 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.
