“Then I heard a loud voice from the temple saying to the seven angels, ‘Go and pour out the bowls of the wrath of God on the earth.’” Revelation 16:1.
“Then the sixth angel poured out his bowl on the great river Euphrates, and its water was dried up, so that the way of the kings from the east might be prepared. And I saw three unclean spirits like frogs coming out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet. For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.” Revelation 16:12-14.
“Then I looked, and behold, a white cloud, and on the cloud sat One like the Son of Man, having on His head a golden crown, and in His hand a sharp sickle. And another angel came out of the temple, crying with a loud voice to Him who sat on the cloud, ‘Thrust in Your sickle and reap, for the time has come for You to reap, for the harvest of the earth is ripe.’ So He who sat on the cloud thrust in His sickle on the earth, and the earth was reaped.” Revelation 14:14-16.
