15 And you are to make upright boards of hard wood for the House. 16 Every board is to be ten cubits high and a cubit and a half wide. 17 Every board is to be joined to the one nearest to it by two tongues, and so for every board in the House. 18 These are the boards needed for the house; twenty boards for the south side, 19 With forty silver bases under the twenty boards, two bases under every board to take its tongues. 20 And twenty boards for the second side of the house on the north, 21 With their forty silver bases, two under every board. 22 And six boards for the back of the House on the west, 23 With two boards for the angles of the House at the back. 24 The two are to be joined together at the base and at the top to one ring, forming the two angles. 25 So there are to be eight boards, with their sixteen silver bases, two bases under every board. 26 And make rods of the same wood, five for the boards on the one side, 27 And five for the boards on the other side of the House, and five for the west side of the House at the back. 28 And the middle rod is to go through the rings of all the boards from end to end. 29 And the boards are to be plated with gold, having gold rings for the rods to go through: and the rods are to be plated with gold. 30 And you are to make the House from the design which you saw 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.
