+Job's Second Speech: A Response to Eliphaz
+
+# Chapter 6
+1. Then Job spoke again:
+
+2. "If my misery could be weighed
+    and my troubles be put on the scales,
+
+3. they would outweigh all the sands of the sea.
+    That is why I spoke impulsively.
+
+4. For the Almighty has struck me down with his arrows.
+    Their poison infects my spirit.
+    God's terrors are lined up against me.
+
+5. Don't I have a right to complain?
+    Don't wild donkeys bray when they find no grass,
+    and oxen bellow when they have no food?
+
+6. Don't people complain about unsalted food?
+    Does anyone want the tasteless white of an egg?
+
+7. My appetite disappears when I look at it;
+    I gag at the thought of eating it!
+
+8. "Oh, that I might have my request,
+    that God would grant my desire.
+
+9. I wish he would crush me.
+    I wish he would reach out his hand and kill me.
+
+10. At least I can take comfort in this:
+    Despite the pain,
+    I have not denied the words of the Holy One.
+
+11. But I don't have the strength to endure.
+    I have nothing to live for.
+
+12. Do I have the strength of a stone?
+    Is my body made of bronze?
+
+13. No, I am utterly helpless,
+    without any chance of success.
+
+14. "One should be kind to a fainting friend,
+    but you accuse me without any fear of the Almighty.
+
+15. My brothers, you have proved as unreliable as a seasonal brook
+    that overflows its banks in the spring
+
+16. when it is swollen with ice and melting snow.
+
+17. But when the hot weather arrives, the water disappears.
+    The brook vanishes in the heat.
+
+18. The caravans turn aside to be refreshed,
+    but there is nothing to drink, so they die.
+
+19. The caravans from Tema search for this water;
+    the travelers from Sheba hope to find it.
+
+20. They count on it but are disappointed.
+    When they arrive, their hopes are dashed.
+
+21. You, too, have given no help.
+    You have seen my calamity, and you are afraid.
+
+22. But why? Have I ever asked you for a gift?
+    Have I begged for anything of yours for myself?
+
+23. Have I asked you to rescue me from my enemies,
+    or to save me from ruthless people?
+
+24. Teach me, and I will keep quiet.
+    Show me what I have done wrong.
+
+25. Honest words can be painful,
+    but what do your criticisms amount to?
+
+26. Do you think your words are convincing
+    when you disregard my cry of desperation?
+
+27. You would even send an orphan into slavery
+    or sell a friend.
+
+28. Look at me!
+    Would I lie to your face?
+
+29. Stop assuming my guilt,
+    for I have done no wrong.
+
+30. Do you think I am lying?
+    Don't I know the difference between right and wrong?
+
+
