Exodus 26:15 - Wesley's Explanatory Notes

Very particular directions are here given about the boards of the tabernacle, which were to bear up the curtains. These had tenons which fell into the mortaises that were made for them in silver bases. The boards were coupled together with gold rings at top and bottom, and kept firm with bars that run through golden staples in every board. Thus every thing in the tabernacle was very splendid, agreeable to that infant state of the church, when such things were proper to possess the minds of the worshippers with a reverence of the divine glory. 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.
