15 "And for the tabernacle you shall make the boards of acacia wood, standing upright. 16 Ten cubits shall be the length of a board, and a cubit and a half shall be the width of each board. 17 Two tenons shall be in each board for binding one to another. Thus you shall make for all the boards of the tabernacle. 18 And you shall make the boards for the tabernacle, twenty boards for the south side. 19 You shall make forty sockets of silver under the twenty boards: two sockets under each of the boards for its two tenons. 20 And for the second side of the tabernacle, the north side, there shall be twenty boards 21 and their forty sockets of silver: two sockets under each of the boards. 22 For the far side of the tabernacle, westward, you shall make six boards. 23 And you shall also make two boards for the two back corners of the tabernacle. 24 They shall be coupled together at the bottom and they shall be coupled together at the top by one ring. Thus it shall be for both of them. They shall be for the two corners. 25 So there shall be eight boards with their sockets of silver--sixteen sockets--two sockets under each board. 26 "And you shall make bars of acacia wood: five for the boards on one side of the tabernacle, 27 five bars for the boards on the other side of the tabernacle, and five bars for the boards of the side of the tabernacle, for the far side westward. 28 The middle bar shall pass through the midst of the boards from end to end. 29 You shall overlay the boards with gold, make their rings of gold as holders for the bars, and overlay the bars with gold. 30 And you shall raise up the tabernacle according to its pattern which 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.
