+# Chapter 37
+1. "My heart pounds as I think of this.
+    It trembles within me.
+
+2. Listen carefully to the thunder of God's voice
+    as it rolls from his mouth.
+
+3. It rolls across the heavens,
+    and his lightning flashes in every direction.
+
+4. Then comes the roaring of the thunder--
+    the tremendous voice of his majesty.
+    He does not restrain it when he speaks.
+
+5. God's voice is glorious in the thunder.
+    We can't even imagine the greatness of his power.
+
+6. "He directs the snow to fall on the earth
+    and tells the rain to pour down.
+
+7. Then everyone stops working
+    so they can watch his power.
+
+8. The wild animals take cover
+    and stay inside their dens.
+
+9. The stormy wind comes from its chamber,
+    and the driving winds bring the cold.
+
+10. God's breath sends the ice,
+    freezing wide expanses of water.
+
+11. He loads the clouds with moisture,
+    and they flash with his lightning.
+
+12. The clouds churn about at his direction.
+    They do whatever he commands throughout the earth.
+
+13. He makes these things happen either to punish people
+    or to show his unfailing love.
+
+14. "Pay attention to this, Job.
+    Stop and consider the wonderful miracles of God!
+
+15. Do you know how God controls the storm
+    and causes the lightning to flash from his clouds?
+
+16. Do you understand how he moves the clouds
+    with wonderful perfection and skill?
+
+17. When you are sweltering in your clothes
+    and the south wind dies down and everything is still,
+
+18. he makes the skies reflect the heat like a bronze mirror.
+    Can you do that?
+
+19. "So teach the rest of us what to say to God.
+    We are too ignorant to make our own arguments.
+
+20. Should God be notified that I want to speak?
+    Can people even speak when they are confused?
+
+21. We cannot look at the sun,
+    for it shines brightly in the sky
+    when the wind clears away the clouds.
+
+22. So also, golden splendor comes from the mountain of God.
+    He is clothed in dazzling splendor.
+
+23. We cannot imagine the power of the Almighty;
+    but even though he is just and righteous,
+    he does not destroy us.
+
+24. No wonder people everywhere fear him.
+    All who are wise show him reverence."
