The revelation of the eviction of Satan was
given to the Prophet Daniel.

But in his day, the time hadn't come yet
for the prophecy to be fulfilled. So the
words of the book were sealed up till the
time of the end.

Christ hadn't come as Redeemer; He hadn't
paid the ransom; and He wasn't the "Lamb
that had been slain" yet. Revelation 5:6

"And he said, Go thy way, Daniel: for the
words are closed up and sealed until the
time of the end." Daniel 12:9
