SEV Biblia, Chapter 26:29
Y cubrirás las tablas de oro, y harás sus anillos de oro para meter por ellos las barras; también cubrirás las barras de oro.
Clarke's Bible Commentary - Exodus 26:29
Verse 29. Thou shalt overlay the boards with gold] It is not said how thick the gold was by which these boards, &c., were overlaid; it was no doubt done with gold plates, but these must have been very thin, else the boards, &c., must have been insupportably heavy. The gold was probably something like our gold leaf, but not brought to so great a degree of tenuity.
Matthew Henry Commentary
Verses 15-30 - The sockets of silver each weighed about 115 pounds; they were place in rows on the ground. In every pair of these sockets, a strong boar of shittim-wood, covered with plates of gold, was fitted by mortise and tenons. Thus walls were formed for the two sides, and for the wes end. The wall was further held together by bars, which passed throug 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 wa a type of the church of God, built upon the foundation of the apostle and prophets, Jesus Christ himself being the chief Corner-stone, Ep 2:20, 21.
