Isaiah 29:10-12

10For Jehovah hath poured out upon you a spirit of deep sleep, and hath closed your eyes; the prophets and your chiefs, the seers, hath he covered.

11And the whole vision is become unto you as the words of a book that is sealed, which they give to one that can read, saying, Read this, I pray thee; and he saith, I cannot, for it is sealed.

12And they give the book to him that cannot read, saying, Read this, I pray thee; and he saith, I cannot read.
