Isaiah 29:10-12, 18

For the LORD hath poured out upon you the spirit of deep sleep, and hath closed your eyes: the prophets and your rulers, the seers hath he covered. And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed: and the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.

And in that day shall the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity, and out of darkness.
