19 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.
19 and make forty silver bases to go under them-two bases for each frame, one under each projection.
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;
19 with forty silver sockets to receive the two pegs from each of the twenty frames;
19 You shall make forty sockets of silver under the twenty boards: two sockets under each of the boards for its two tenons.
19 Also make forty silver bases-two bases under each frame, with the pegs fitting securely into the bases.

Commentary on Exodus 26:15-30
(Read Exodus 26:15-30)
The sockets of silver each weighed about 115 pounds; they were placed in rows on the ground. In every pair of these sockets, a strong board of shittim-wood, covered with plates of gold, was fitted by mortises and tenons. Thus walls were formed for the two sides, and for the west end. The wall was further held together by bars, which passed through rings of gold. Over this the curtains were spread. Though movable, it was strong and firm. The materials were very costly. In all this it was a type of the church of God, built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief Corner-stone, Ephesians 2:20,21.
