Verse 29. - The rings were to be of solid gold; the boards and the bars of acacia wood overlaid with gold.

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.And thou shalt overlay the boards with gold,.... Not merely gild them, but cover them with thin plates of gold; and which, because it would take up a great quantity of gold, and make the boards very heavy, unless the plates were very thin, when they were taken down and carried from place to place, some have thought they were only glided:

and make their rings of gold, for places for the bars; these were made of solid gold, and were as staples to let the bars into: and, according to Jarchi, there were two rings to every board:

and thou shalt overlay the bars with gold: cover them with plates of gold; and these bars and staples of gold show how compact and firm the church of God is, through his almighty power, as well as how glorious and splendid it is by his grace.
