Exodus 26:16-21

26:16 Each frame is to be fifteen feet long, and each frame is to be two feet three inches wide, 26:17 with two projections per frame parallel one to another. You are to make all the frames of the tabernacle in this way. 26:18 So you are to make the frames for the tabernacle: twenty frames for the south side, 26:19 and you are to make forty silver bases to go under the twenty frames – two bases under the first frame for its two projections, and likewise two bases under the next frame for its two projections; 26:20 and for the second side of the tabernacle, the north side, twenty frames, 26:21 and their forty silver bases, two bases under the first frame, and two bases under the next frame.
