Job 28:2-6

2They know where to dig iron from the earth and how to smelt copper from rock.

3They know how to shine light in the darkness and explore the farthest regions of the earth as they search in the dark for ore.

4They sink a mine shaft into the earth far from where anyone lives. They descend on ropes, swinging back and forth.

5Food is grown on the earth above, but down below, the earth is melted as by fire.

6Here the rocks contain precious lapis lazuli, and the dust contains gold.
