SEV Biblia, Chapter 28:2
El hierro es tomado del polvo, y de la piedra es fundido el metal.
Clarke's Bible Commentary - Job 28:2
Verse 2. Iron is taken out of the earth ] This most useful metal is hidden under the earth, and men have found out the method of separating it from its ore. Brass is molten out of the stone. ] As brass is a factitious metal, copper must be the meaning of the Hebrew word hwjn nechusah: literally, the stone is poured out for brass. If we retain the common translation, perhaps the process of making brass may be that to which Job refers; for this metal is formed from copper melted with the stone calamine; and thus the stone is poured out to make brass.
Matthew Henry Commentary
Verses 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. God 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 muc easier, and safer! Yet gold is sought for, but grace neglected. Wil the hopes of precious things out of the earth, so men call them, thoug really they are paltry and perishing, be such a spur to industry, an shall not the certain prospect of truly precious things in heaven be much more so?
