Isaiah 29:9-12

9Astonish yourselves and be astonished; blind yourselves and be blind! Be drunk, but not with wine; stagger, but not with strong drink!

10For the Lord has poured out upon you a spirit of deep sleep, and has closed your eyes (the prophets), and covered your heads (the seers).

11And the vision of all this has become to you like the words of a book that is sealed. When men give it to one who can read, saying, "Read this," he says, "I cannot, for it is sealed."

12And when they give the book to one who cannot read, saying, "Read this," he says, "I cannot read."
