+Job Speaks of Wisdom and Understanding
+
+# Chapter 28
+1. "People know where to mine silver
+    and how to refine gold.
+
+2. They know where to dig iron from the earth
+    and how to smelt copper from rock.
+
+3. They know how to shine light in the darkness
+    and explore the farthest regions of the earth
+    as they search in the dark for ore.
+
+4. They sink a mine shaft into the earth
+    far from where anyone lives.
+    They descend on ropes, swinging back and forth.
+
+5. Food is grown on the earth above,
+    but down below, the earth is melted as by fire.
+
+6. Here the rocks contain precious lapis lazuli,
+    and the dust contains gold.
+
+7. These are treasures no bird of prey can see,
+    no falcon's eye observe.
+
+8. No wild animal has walked upon these treasures;
+    no lion has ever set his paw there.
+
+9. People know how to tear apart flinty rocks
+    and overturn the roots of mountains.
+
+10. They cut tunnels in the rocks
+    and uncover precious stones.
+
+11. They dam up the trickling streams
+    and bring to light the hidden treasures.
+
+12. "But do people know where to find wisdom?
+    Where can they find understanding?
+
+13. No one knows where to find it,
+    for it is not found among the living.
+
+14. 'It is not here,' says the ocean.
+    'Nor is it here,' says the sea.
+
+15. It cannot be bought with gold.
+    It cannot be purchased with silver.
+
+16. It's worth more than all the gold of Ophir,
+    greater than precious onyx or lapis lazuli.
+
+17. Wisdom is more valuable than gold and crystal.
+    It cannot be purchased with jewels mounted in fine gold.
+
+18. Coral and jasper are worthless in trying to get it.
+    The price of wisdom is far above rubies.
+
+19. Precious peridot from Ethiopia cannot be exchanged for it.
+    It's worth more than the purest gold.
+
+20. "But do people know where to find wisdom?
+    Where can they find understanding?
+
+21. It is hidden from the eyes of all humanity.
+    Even the sharp-eyed birds in the sky cannot discover it.
+
+22. Destruction and Death say,
+    'We've heard only rumors of where wisdom can be found.'
+
+23. "God alone understands the way to wisdom;
+    he knows where it can be found,
+
+24. for he looks throughout the whole earth
+    and sees everything under the heavens.
+
+25. He decided how hard the winds should blow
+    and how much rain should fall.
+
+26. He made the laws for the rain
+    and laid out a path for the lightning.
+
+27. Then he saw wisdom and evaluated it.
+    He set it in place and examined it thoroughly.
+
+28. And this is what he says to all humanity:
+'The fear of the Lord is true wisdom;
+    to forsake evil is real understanding.'"
