The vision of all; of all your prophets, whether the true or false ones. As the words of a book that is sealed; in which no man can read whilst it is scaled up, as books then sometimes were, 1 Kings 21:8 Esther 3:12,13, being made in the form of rolls, which was convenient for that purpose. The book is delivered to him that is not learned; unsealed and opened, as the following clause implies. God so orders the manner of delivering this book, that neither the learned nor unlearned could read and understand it.
