Very particular directions are here given about the boards of the tabernacle, which were to bear up the curtains, as the stakes of a tent which had need to be strong, Isaiah 54:2. These boards had tenons which fell into the mortises that were made for them in silver bases.
God took care to have every thing strong, as well as fine, in his tabernacle. Curtains without boards would have been shaken by every wind; but it is a good thing to have the heart established with grace, which is as the boards to support the curtains of profession, which otherwise will not hold out long.
The boards were coupled together with gold rings at top and bottom (Exodus 26:24), and kept firm with bars that ran through golden staples in every board (Exodus 26:26), and the boards and bars were all richly gilded, Exodus 26:29.
Thus every thing in the tabernacle was very splendid, agreeable to that infant state of the church, when such things were proper enough to please children, to possess the minds of the worshippers with a reverence of the divine glory, and to affect them with the greatness of that prince who said, Here will I dwell; in allusion to this the new Jerusalem is said to be of pure gold, Revelation 21:18.
But the builders of the gospel church said, Silver and gold have we none; and yet the glory of their building far exceeded that of the tabernacle, 2 Corinthians 3:10-11. How much better is wisdom than gold!
No orders are given here about the floor of the tabernacle; probably that also was boarded; for we cannot think that within all these fine curtains they trod upon the cold or wet ground; if it was so left, it may remind us of Exodus 20:24, An altar of earth shalt thou make unto me.
