"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." Daniel 12:4

There is going to be an unusual increase of

knowledge;
There is going to be an unusual increase in
travel upon the earth;
earthquakes in various places;
and distress of nations.
Luke 21:11, 25
