Isaiah 29:11,12

And the vision of all Of all your prophets, or every vision; is unto you as the words of a book that is sealed Which no man can read while it is sealed up, as books then sometimes were, being in the form of rolls. Which men deliver to one that is learned That understands the language in which the book is written; saying, Read this he saith, I cannot; for it is sealed Mere human learning, without supernatural illumination, will not enable any man rightly to understand the word of God, and things divine: see 1 Corinthians 2:11; 1 Corinthians 2:14. The book is delivered Unsealed and opened; to him that is unlearned and he saith, I cannot read it; for I am unlearned. Thus, neither the learned nor the unlearned among the Jews were any better for the messages which God sent them by his servants the prophets, nor desired to be better.
