Isaiah 29:10-12, 18

For the LORD has poured over you a spirit of deep sleep, He has shut your eyes, the prophets; And He has covered your heads, the seers. The entire vision will be to you like the words of a sealed book, which when they give it to the one who is literate, saying, “Please read this,” he will say, “I cannot, for it is sealed.” Then the book will be given to the one who is illiterate, saying, “Please read this.” And he will say, “I cannot read.”

On that day the deaf will hear words of a book, And out of their gloom and darkness the eyes of the blind will see.
