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 thou shalt make bars of shittim wood, Which being put into rings or staples of gold, kept the boards tight, close, and firm together:

five for the boards of the one side of the tabernacle: for instance, the south side; four of these were placed, two at the upper end of the boards, and two at the lower end, and the fifth in the middle, particularly taken notice of, Exo 26:28, how long these bars were it is not said, but it is reasonable to conclude that they reached the length of the tabernacle, which was thirty cubits; and as it was not easy to get bars of such a length, the notion of Josephus (u) perhaps, may be right, that each two consisted of divers parts which joined one another, the head of one entering into the hollow of the other and as he supposes they were five cubits long, a row of them must have six parts, which went along the sides, north and south, and the west end two, which was but ten cubits.

(u) Ut supra. (Antiqu. l. 3. c. 6. sect. 3.)

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.
