The ten horns represent ten kings who will reign at the very end for a short time as vassals to the
Antichrist (Rev 17:12-13). Because the Promised Land is ruled by the
fourth empire, these horns likely represent the leaders for the rest of the world who will, in alliance with
Satan's Antichrist, assemble at Armageddon to defend against Jesus who is coming to claim His kingdom
(Rev 19:19).
While the ten horns follow the seventh king, the Scarlet Beast and Antichrist, they resist the dominion of
the Great Harlot, which is likely the world's seductive lifestyle and culture, in the pursuit of their own
worldview and lusts.
Whether it is Babylon or the "common purpose" of each of the ten kings (horns), they all represent a secular
worldview that extinguished any perspective of God and compelled people to rise up and fight in Armageddon.
