Isaiah 29:9-12

9Stop and be astonished; blind yourselves and be blind! They are drunk, but not with wine; they stagger, but not with beer.

10For the Lord has poured out on you an overwhelming urge to sleep; he has shut your eyes (the prophets) and covered your heads (the seers).

11For you the entire vision will be like the words of a sealed document. If it is given to one who can read and he is asked to read it, he will say, “I can’t read it, because it is sealed.”

12And if the document is given to one who cannot read and he is asked to read it, he will say, “I can’t read.”
