Isaiah 29:10-12

10The Lord has brought over you a deep sleep: He has sealed your eyes (the prophets); he has covered your heads (the seers). 11For you this whole vision is nothing but words sealed in a scroll. And if you give the scroll to someone who can read, and say, “Read this, please,” they will answer, “I can’t; it is sealed.” 12Or if you give the scroll to someone who cannot read, and say, “Read this, please,” they will answer, “I don’t know how to read.”
