Translation
Then I saw the BEAST and the kings of
the earth and
their armies
gathered together to
make war against the One sitting on the horse
and against His army.
Paraphrase
Then I saw THE FEROCIOUS CREATURE and the power-brokers of the earth, along with all who followed them, willingly or unwillingly,
gathered together to
oppose the One who is powerful, decisive and cannot be avoided or turned back and against those who follow Him.
