Daniel closes the book (Dan 12:4-12:4)

“But you!

Daniel!

Keep the words secret!

Keep the book sealed,

Until the time

Of the end!

Many shall be running

Back and forth.

Knowledge with evil

Shall increase.”

Gabriel then told Daniel to keep these words a secret.  He was to keep the book of life sealed until the end times.  Many people would be running around all over the place.  However, between then and now both knowledge and evil would increase.
