+The LORD's Challenge Continues
+
+# Chapter 41
+1. "Can you catch Leviathan with a hook
+    or put a noose around its jaw?
+
+2. Can you tie it with a rope through the nose
+    or pierce its jaw with a spike?
+
+3. Will it beg you for mercy
+    or implore you for pity?
+
+4. Will it agree to work for you,
+    to be your slave for life?
+
+5. Can you make it a pet like a bird,
+    or give it to your little girls to play with?
+
+6. Will merchants try to buy it
+    to sell it in their shops?
+
+7. Will its hide be hurt by spears
+    or its head by a harpoon?
+
+8. If you lay a hand on it,
+    you will certainly remember the battle that follows.
+    You won't try that again!
+
+9. No, it is useless to try to capture it.
+    The hunter who attempts it will be knocked down.
+
+10. And since no one dares to disturb it,
+    who then can stand up to me?
+
+11. Who has given me anything that I need to pay back?
+    Everything under heaven is mine.
+
+12. "I want to emphasize Leviathan's limbs
+    and its enormous strength and graceful form.
+
+13. Who can strip off its hide,
+    and who can penetrate its double layer of armor?
+
+14. Who could pry open its jaws?
+    For its teeth are terrible!
+
+15. The scales on its back are like rows of shields
+    tightly sealed together.
+
+16. They are so close together
+    that no air can get between them.
+
+17. Each scale sticks tight to the next.
+    They interlock and cannot be penetrated.
+
+18. "When it sneezes, it flashes light!
+    Its eyes are like the red of dawn.
+
+19. Lightning leaps from its mouth;
+    flames of fire flash out.
+
+20. Smoke streams from its nostrils
+    like steam from a pot heated over burning rushes.
+
+21. Its breath would kindle coals,
+    for flames shoot from its mouth.
+
+22. "The tremendous strength in Leviathan's neck
+    strikes terror wherever it goes.
+
+23. Its flesh is hard and firm
+    and cannot be penetrated.
+
+24. Its heart is hard as rock,
+    hard as a millstone.
+
+25. When it rises, the mighty are afraid,
+    gripped by terror.
+
+26. No sword can stop it,
+    no spear, dart, or javelin.
+
+27. Iron is nothing but straw to that creature,
+    and bronze is like rotten wood.
+
+28. Arrows cannot make it flee.
+    Stones shot from a sling are like bits of grass.
+
+29. Clubs are like a blade of grass,
+    and it laughs at the swish of javelins.
+
+30. Its belly is covered with scales as sharp as glass.
+    It plows up the ground as it drags through the mud.
+
+31. "Leviathan makes the water boil with its commotion.
+    It stirs the depths like a pot of ointment.
+
+32. The water glistens in its wake,
+    making the sea look white.
+
+33. Nothing on earth is its equal,
+    no other creature so fearless.
+
+34. Of all the creatures, it is the proudest.
+    It is the king of beasts."
