Isaiah 29:10-12

For the LORD has poured out on you a spirit of deep sleep. He has closed the eyes of your prophets and visionaries. All the future events in this vision are like a sealed book to them. When you give it to those who can read, they will say, “We can’t read it because it is sealed.” When you give it to those who cannot read, they will say, “We don’t know how to read.”
