The heads of the Beast have 10 horns who are now 10 kings, spiritual entities, demonic spirits. The Destroyer (the Beast) is one of the horns. These 10 now receive authority with the Beast but will be able to exercise it for one hour only, the hour of testing, the hour of judgment, the one hour in which they will attack the woman who rides the Beast and destroy her. They all have one mind and one purpose, and they give their power and authority to the Beast.
They will in the future wage war against the Lamb and the
Lamb will defeat them because He now is Lord of lords and King of kings, and those with Him Called and Chosen and Faithful.
