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:

10 For the LORD has poured out on you a spirit of deep sleep, and has closed your eyes, the prophets; and he has covered your heads, the seers.
11 All vision has become to you like the words of a book that is sealed, which men deliver to one who is educated, saying, “Read this, please;” and he says, “I can’t, for it is sealed;”
