+Job's First Speech
+
+# Chapter 3
+1. At last Job spoke, and he cursed the day of his birth.
+2. He said:
+
+3. "Let the day of my birth be erased,
+    and the night I was conceived.
+
+4. Let that day be turned to darkness.
+    Let it be lost even to God on high,
+    and let no light shine on it.
+
+5. Let the darkness and utter gloom claim that day for its own.
+    Let a black cloud overshadow it,
+    and let the darkness terrify it.
+
+6. Let that night be blotted off the calendar,
+    never again to be counted among the days of the year,
+    never again to appear among the months.
+
+7. Let that night be childless.
+    Let it have no joy.
+
+8. Let those who are experts at cursing--
+    whose cursing could rouse Leviathan--
+    curse that day.
+
+9. Let its morning stars remain dark.
+    Let it hope for light, but in vain;
+    may it never see the morning light.
+
+10. Curse that day for failing to shut my mother's womb,
+    for letting me be born to see all this trouble.
+
+11. "Why wasn't I born dead?
+    Why didn't I die as I came from the womb?
+
+12. Why was I laid on my mother's lap?
+    Why did she nurse me at her breasts?
+
+13. Had I died at birth, I would now be at peace.
+    I would be asleep and at rest.
+
+14. I would rest with the world's kings and prime ministers,
+    whose great buildings now lie in ruins.
+
+15. I would rest with princes, rich in gold,
+    whose palaces were filled with silver.
+
+16. Why wasn't I buried like a stillborn child,
+    like a baby who never lives to see the light?
+
+17. For in death the wicked cause no trouble,
+    and the weary are at rest.
+
+18. Even captives are at ease in death,
+    with no guards to curse them.
+
+19. Rich and poor are both there,
+    and the slave is free from his master.
+
+20. "Oh, why give light to those in misery,
+    and life to those who are bitter?
+
+21. They long for death, and it won't come.
+    They search for death more eagerly than for hidden treasure.
+
+22. They're filled with joy when they finally die,
+    and rejoice when they find the grave.
+
+23. Why is life given to those with no future,
+    those God has surrounded with difficulties?
+
+24. I cannot eat for sighing;
+    my groans pour out like water.
+
+25. What I always feared has happened to me.
+    What I dreaded has come true.
+
+26. I have no peace, no quietness.
+    I have no rest; only trouble comes."
+
