Isaiah 29:10-11

29:10 For the Lord has poured out on you

a strong urge to sleep deeply.

He has shut your eyes (the prophets),

and covered your heads (the seers).

29:11 To you this entire prophetic revelation is like words in a sealed scroll. When they hand it to one who can read and say, “Read this,” he responds, “I can’t, because it is sealed.”
