15 You shall make upright frames of acacia wood for the tabernacle. 16 Ten cubits shall be the length of a frame, and a cubit and a half the width of each frame. 17 There shall be two pegs in each frame to fit the frames together; you shall make these for all the frames of the tabernacle. 18 You shall make the frames for the tabernacle: twenty frames for the south side; 19 and you shall make forty bases of silver under the twenty frames, two bases under the first frame for its two pegs, and two bases under the next frame for its two pegs; 20 and for the second side of the tabernacle, on the north side twenty frames, 21 and their forty bases of silver, two bases under the first frame, and two bases under the next frame; 22 and for the rear of the tabernacle westward you shall make six frames. 23 You shall make two frames for corners of the tabernacle in the rear; 24 they shall be separate beneath, but joined at the top, at the first ring; it shall be the same with both of them; they shall form the two corners. 25 And so there shall be eight frames, with their bases of silver, sixteen bases; two bases under the first frame, and two bases under the next frame. 26 You shall make bars of acacia wood, five for the frames of the one side of the tabernacle, 27 and five bars for the frames of the other side of the tabernacle, and five bars for the frames of the side of the tabernacle at the rear westward. 28 The middle bar, halfway up the frames, shall pass through from end to end. 29 You shall overlay the frames with gold, and shall make their rings of gold to hold the bars; and you shall overlay the bars with gold. 30 Then you shall erect the tabernacle according to the plan for it that you were shown on the mountain.

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.
