Isaiah 29:10-12, 18

The LORD has brought over you a deep sleep: He has sealed your eyes (the prophets); he has covered your heads (the seers). For 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.” Or 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.”

In that day the deaf will hear the words of the scroll, and out of gloom and darkness the eyes of the blind will see.
