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, Isa 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 (Exo 26:24), and kept firm with bars that ran through golden staples in every board (Exo 26:26), and the boards and bars were all richly gilded, Exo 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, Rev 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, Co2 3:10, Co2 3:11. 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 Exo 20:24, An altar of earth shalt thou make unto me.

Ten cubits shall be the length of a board - Each of these boards or planks was about five yards and two feet and a half long, and thirty-two inches broad; and as they are said to be standing up, this was the Height of the tabernacle. The length being thirty cubits, twenty boards, one cubit and a half broad each, make about seventeen yards and a half, and the Breadth was about five yards.

And they shall be coupled together beneath,.... At the bottom of the boards or planks:

and they shall be coupled together above the head of it unto one ring at the top of the boards there was a ring, to which they were coupled and fastened, and so at the bottom of them, though not expressed: some understand this of all the planks, both at the two sides and at the west end; but it seems rather to respect only the corner planks, since it follows:

thus shall it be for them both, they shall be for the two corners; which were coupled and joined alike at each corner as if they were twins, as the word used signifies; or the meaning is, that these were double boards, and so like twins, which were so closely put together that they seemed but one board; which was done that the corners might be thicker and stronger, and so for the greater firmness of the building.

thou shalt make boards . . . rear up the tabernacle according to the fashion . . . which was showed thee--The tabernacle, from its name as well as from its general appearance and arrangements, was a tent; but from the description given in these verses, the boards that formed its walls, the five (cross) bars that strengthened them, and the middle bar that "reached from end to end," and gave it solidity and compactness, it was evidently a more substantial fabric than a light and fragile tent, probably on account of the weight of its various coverings as well as for the protection of its precious furniture.
