Exodus 26:15-25

26:15 “You are to make the frames for the tabernacle out of acacia wood as uprights. 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. 26:22 And for the back of the tabernacle on the west you will make six frames. 26:23 You are to make two frames for the corners of the tabernacle on the back. 26:24 At the two corners they must be doubled at the lower end and finished together at the top in one ring. So it will be for both. 26:25 So there are to be eight frames and their silver bases, sixteen bases, two bases under the first frame, and two bases under the next frame.

Exodus 40:18-19

40:18 When Moses set up the tabernacle and put its bases in place, he set up its frames, attached its bars, and set up its posts. 40:19 Then he spread the tent over the tabernacle and put the covering of the tent over it, as the Lord had commanded Moses.
