Revelation 11:18
And the nations were enraged, but your wrath has come [anyway]. The time has come for the dead to be judged and for your servants the prophets to receive their reward, [along with] the saints and [both] the insignificant and important ones who revere your name. [It is also time] to destroy those who destroy the earth."
Revelation 16:6
For they [i.e., the followers of the beast. See verse 2] have shed the blood of God's holy people and [their] prophets, and you have given them blood to drink because they deserved it [i.e., these persecutors deserved the punishment they received for shedding blood].
Revelation 16:14
For they are spirits of demons, which perform [supernatural] signs. These spirits go out to the kings of the whole world to assemble them for battle on the great day of Almighty God.
Revelation 16:16
So, the [demonic] spirits assembled the kings together at the place which is called "Armageddon" in Hebrew. [Note: "Armageddon" means "mountain of Megiddo" and was a site in northwestern Palestine where several decisive battles had been fought centuries earlier. See Judges 4,5,7].
Revelation 18:20-21
Be glad, heaven, and you saints, and you apostles, and you prophets, for God has brought judgment on her for you [i.e., for the way she treated you].'"
Revelation 19:19-21
Then I saw the beast [See 13:1ff], and the kings of the earth and their armies assembled together to wage war against the One who was riding on the horse [i.e., Christ. See verse 11] and His army.
Revelation 20:8
and he will [again] go out to deceive the nations which are [located] throughout the whole world --- Gog and Magog. [Note: Based on Eze. 35-40, it appears that these names are used here figuratively for all the forces of wickedness which are enemies of God]. Satan will assemble them together for battle, and they will be as numberless as the sand on the seashore.
