Revelation 19:19

John now saw another scene on earth. The beast at this time will have 10 allies (Revelation 17:12-14; cf. Psalms 2:2). Their armies will represent the worldwide population of earth-dwellers. These armies will unite to oppose Christ (Revelation 16:13-16). The battle will be over world leadership. When Jesus Christ returns, the beast’s 10 allies that will have been fighting each other (Ezekiel 38:21; Daniel 11:40-44) will unite against Christ (Revelation 16:14). This is a description of the judgment portrayed proleptically in Revelation 14:14-20. It is surprisingly brief in view of its importance in history. This probably indicates that the battle will not last long (cf. Matthew 24:13-45).

"The Seer is not describing the gradual conquest of evil in the spiritual struggles of the faithful, but a great historic event which brings to an end the Antichrist and his forces and ushers in the long-awaited era of righteousness." [Note: Mounce, p. 349.]
