Daniel 8:26-27 (New King James Version)

²⁶ “ And the vision of the evenings and mornings
      Which was told is true;
      Therefore seal up the vision,
      For it refers to many days in the future.”

²⁷ And I, Daniel, fainted and was sick for days; afterward I arose and went about the king’s business. I was astonished by the vision, but no one understood it.
