And the vision of all has 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 you: and he says, I cannot; for it is sealed:
All Commentaries on Isaiah 29:11 Go To Isaiah 29
Primasius of Hadrumetum
AD 560
This is also why Isaiah would say to the Jews: “Behold, all of these words will be to you like the words of a sealed book.” The skilled reader and the illiterate are equally said to be deprived of fruit, since one is prevented by the seal from penetrating what lies hidden within and the other is shackled by ignorance.
