Daniel 12:4

"But thou, 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."

"Shut up the words, and seal the book, even to the time of the end ..." Keil stated that the true meaning of shut up and seal is that of "guarding and protecting the message" that it might be available to future generations."[13] Moreover, it is perfectly obvious that the instructions thus to guard and protect the message "refers to the whole Book of Daniel."[14]

"Men shall run to and fro, and knowledge shall be increased ..." Some interpreters have tried to apply this to persons letting their eyes run to and fro searching for the truth; but we cannot find anything like that in the passage. If men will just look at the travel to and from upon the planet earth by men of all nations throughout this whole century, they could not fail to be impressed with the truth that this going "to and fro" on the earth has been multiplied fantastically above everything that was even dreamed of a hundred years ago. Is not this prophesied here as being a development "at the time of the end"?

Likewise, has not knowledge been "increased"? In the field of medicine, more knowledge has been learned in the past century than in all previous centuries put together. Furthermore, this same phenomenon may be noted in any one of a hundred different fields of knowledge. Take transportation, chemistry, biology, agriculture, space travel, etc., etc., Is it not a fact that "knowledge has been increased"? Does this mean, therefore, that we are indeed approaching the time of the end? Our own conviction is that the answer is undoubtedly affirmative.
