| Geneva Study Bible Iron is taken out of the earth, and brass is molten out of the stone. King James Translators' Notes earth: or, dust Jamieson-Fausset-Brown Bible Commentary 2. brass-that is, copper; for brass is a mixed metal of copper and zinc, of modern invention. Iron is less easily discovered, and wrought, than copper; therefore copper was in common use long before iron. Copper-stone is called "cadmium" by Pliny [Natural History, 34:1; 36:21]. Iron is fitly said to be taken out of the "earth" (dust), for ore looks like mere earth. Matthew Henry's Concise Commentary 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? |
