• Deuteronomy 28:28-29
  The LORD will strike you with madness and blindness and confusion of heart. And you shall grope at noonday, as a blind man gropes in darkness; you shall not prosper in your ways; you shall be only oppressed and plundered continually, and no one shall save you.
   
• Ecclesiastes 2:1-2
  I said in my heart, “Come now, I will test you with mirth; therefore enjoy pleasure”; but surely, this also was vanity. I said of laughter—“Madness!”; and of mirth, “What does it accomplish?”
   
• Ecclesiastes 2:12-13
  Then I turned myself to consider wisdom and madness and folly;
  For what can the man do who succeeds the king?—
  Only what he has already done.
  Then I saw that wisdom excels folly
  As light excels darkness.
