The ten toes on the
image that Nebuchadnezzar saw are
the same ten horns of the book of
Daniel and are the same ten horns in
the book of Revelation. They
are ten kings from ten different
countries -- five from the western
old Roman Empire and five from the
eastern old Roman Empire which make
up the one kingdom of the beast.
As for the 3 kings
(horns) plucked up by roots by
another horn called the Little Horn
or Antichrist, and these 3 kings
fell and are subdued by him, they
would have to be replaced by the
Little Horn in order for there to be
10 kings who give their power and
strength to the beast. These
10 kings destroy the city Mystery
Babylon during the Great Tribulation
period so these 10 kings have to
around for this to take place during
that time period.
