28:6 The stones of it [are] the place {f} of sapphires: and it hath dust of gold.

(f) He alludes to the mines and secrets of nature, which are under the earth, into which neither souls nor beasts can enter.

28:6 Sapphires - Of precious stones; the sapphire, is one of the most eminent, being put for all the rest. In some parts of the earth, the sapphires are mixed with stones, and cut out of them and polished. Hath - The earth continueth. Dust - Distinct from that gold which is found in the mass, both sorts of gold being found in the earth.

28:1-11 Job maintained that the dispensations of Providence were regulated by the highest wisdom. To confirm this, he showed of what a great deal of knowledge and wealth men may make themselves masters. The caverns of the earth may be discovered, but not the counsels of Heaven. Go to the miners, thou sluggard in religion, consider their ways, and be wise. Let their courage and diligence in seeking the wealth that perishes, shame us out of slothfulness and faint-heartedness in labouring for the true riches. How much better is it to get wisdom than gold! How much easier, and safer! Yet gold is sought for, but grace neglected. Will the hopes of precious things out of the earth, so men call them, though really they are paltry and perishing, be such a spur to industry, and shall not the certain prospect of truly precious things in heaven be much more so?
