(30) According to the fashion thereof which was shewed thee.—See Exodus 25:9; Exodus 25:40. However minute—even tediously minute—the description, there would necessarily have been a multitude of particulars, not to be described in words, where Moses would have to be guided by the pattern that he had seen.

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.In the midst of the boards - If we suppose the boards to have been of ordinary thickness Exodus 26:16, the bar was visible and passed through an entire row of rings. In any case, it served to hold the whole wall together.15-30. 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. Either by visible representation to his eye, or rather by mental vision or impression of it upon his imagination.

And thou shall rear up the tabernacle,.... When thus finished, and all the furniture belonging to it completed:

according to the fashion thereof, which was showed thee in the mount; this is the third time that this is observed to Moses in the account of the tabernacle; which shows how punctually God would have the pattern observed he had given him, and that all things might be particularly and exactly done according to it, see Hebrews 8:5.

And thou shalt rear up the tabernacle according to the fashion thereof which was showed thee in the mount.
