Job 28:1-4

“Surely there is a mine for silver, And a place where they refine gold. “Iron is taken out of the earth, And copper is smelted from the stone ore. “Man puts an end to darkness [by bringing in a light], And to the farthest bounds he searches out The rock buried in gloom and deep shadow. “He breaks open (mine) shafts far away from where people live, [In places] forgotten by the [human] foot; They dangle [in the mines] and hang away from men.
