But you, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
All Commentaries on Daniel 12:4 Go To Daniel 12
Aquinas Study Bible
AD 2017
He who had revealed manifold truth to Daniel now signifies that the things he has said are matters of secrecy, and he orders him to roll up the scroll containing his words and set a seal upon the book, with the result that many shall read it and inquire as to its fulfilment in history, differing in their opinions because of its great obscurity. And as for the statement, "Many shall pass over" or "go through," this indicates that it will be read by many people. For it is a familiar expression to say: "I have gone through a book," or, "I have passed through an historical account." But that book can be opened by one who has learned the mysteries of Scripture and understands its hidden truths, and its words which seem dark because of the greatness of the secrets they contain. He it is who can interpret the parables and transmute the letter which killeth into the spirit which quickeneth. (St. Jerome)
