Job 28:2-5 New King James Version (NKJV)

2. Iron is taken from the earth,And copper is smelted from ore.

3. Man puts an end to darkness,And searches every recessFor ore in the darkness and the shadow of death.

4. He breaks open a shaft away from people;In places forgotten by feetThey hang far away from men;They swing to and fro.

5. As for the earth, from it comes bread,But underneath it is turned up as by fire;
