Read Isaiah 29:11 Using Other Translations
And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed:
And the vision of all this has become to you like the words of a book that is sealed. When men give it to one who can read, saying, "Read this," he says, "I cannot, for it is sealed."
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.”
