What or who is the little horn in the book of Daniel?
"I was considering the horns, and there was another horn, a little one, coming up among them, before whom three of the first horns were plucked out by the roots. And there, in this horn, were eyes like the eyes of a man, and a mouth speaking pompous words" (Daniel 7:8).
In this verse Daniel was trying to figure out what the ten horns represent when an eleventh horn, that was smaller from the ten, emerged. Three of the ten horns were pulled out by the roots by the eleventh horn. The eleventh horn had the eyes of a man and a mouth, which spoke pride-filled arrogant words.
The ten horns of this fourth beast are the ten kings who rule the world with the beast during the Tribulation. They are given authority to rule with the beast by the devil who gives the beast his authority (Revelation 13:2).
The eleventh horn is the little horn, the beast, who attempts to join the ten nation confederacy. Three of the ten do not want him to join their group so war breaks out and the beast (Antichrist) defeats them. After he takes them down this war spreads to the entire world (Matthew 24:6-7; Revelation 6:3-4) and sets in motion great devastation with one-fourth of the world's population being killed (Revelation 6:8). Those who have come to salvation in Jesus Christ during the Tribulation are blamed for this war and are slaughtered by the millions (Matthew 24:9-10; Revelation 6:9-11).
