Isaiah 6:8-13 (New King James Version)

⁸ Also I heard the voice of the Lord, saying:


      “ Whom shall I send,
      And who will go for Us?”

Then I said, “Here am I! Send me.”
⁹ And He said, “Go, and tell this people:


      ‘ Keep on hearing, but do not understand;
      Keep on seeing, but do not perceive.’
       ¹⁰ “ Make the heart of this people dull,
      And their ears heavy,
      And shut their eyes;
      Lest they see with their eyes,
      And hear with their ears,
      And understand with their heart,
      And return and be healed.”

¹¹ Then I said, “Lord, how long?”

   And He answered:


      “ Until the cities are laid waste and without inhabitant,
      The houses are without a man,
      The land is utterly desolate,
       ¹² The LORD has removed men far away,
      And the forsaken places are many in the midst of the land.
       ¹³ But yet a tenth will be in it,
      And will return and be for consuming,
      As a terebinth tree or as an oak,
      Whose stump remains when it is cut down.
      So the holy seed shall be its stump.”
