And they shall be eight boards,.... Six at the west end and one at each corner, northwest and southwest:

and their sockets of silver, sixteen sockets the same as those for the boards on both sides north and south: they were of the same metal, silver; and they were two under one board, to receive its two tenons as follows:

two sockets under one board, and two sockets under another board; and so under all eight, and which sockets joining with those of the two sides, and in all made ninety six, were the basis and foundation of the tabernacle, and was a figure of Christ, the only foundation of his church and people; and the several tenons of the boards joined into those sockets of silver may denote the union of the members of Christ and ministers of his word to him, and their dependence on him.

Sixteen sockets were to be made for these eight boards, two for each. - Exodus 26:26-29. To fasten the boards, that they might not separate from one another, bars of acacia-wood were to be made and covered with gold, five for each of the three sides of the dwelling; and though it is not expressly stated, yet the reference to rings in Exodus 26:29 as holders of the bars (לבּריחים בּתּים) is a sufficient indication that they were passed through golden rings fastened into the boards.

And they shall be eight boards, and their sockets of silver, sixteen sockets; two sockets under one board, and two sockets under another board.

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, Eph 2:20,21.
