Isaiah 29:9-12

9Tarry ye and wonder, take your pleasure and be blind: they are drunken, but not with wine; they stagger, but not with strong drink.

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

11And all vision 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:

12and the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.
