Job 28:9

He putteth forth his hand upon the rock,.... The discourse is carried on concerning the miner, and digger in the earth for metals and precious stones; who meeting with a rock or flint, and a ridge of them, is not discouraged, but goes to work therewith, and with his hammer in his hand lays upon the rock or flint, and beats it to pieces, and with proper instruments cuts through it; and using fire and vinegar, as Pliny observes, makes his way into it, and oftentimes by splitting it discovers gold or silver, or precious stones, in it:he overturneth the mountains by the roots; or turns them up from the roots; he roots them up, he undermines them; he turns up the earth at the roots of them, to get what is hid at the bottom, or in the bowels of them.
