“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.
“Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth – to every nation, tribe, tongue, and people – saying with a loud voice, ‘Fear God and give glory to Him, for the hour of His judgment has come; and worship Him who made heaven and earth, the sea and springs of water.’” Revelation 14:6-7.
“Then I was given a reed like a measuring rod. And the angel stood, saying, ‘Rise and measure the temple of God, the altar, and those who worship there. But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city underfoot for forty-two months.’” Revelation 11:1-2.
“The first angel sounded: And hail and fire followed, mingled with blood, and they were thrown to the earth; and a third of the trees were burned up, and all green grass was burned up.” Revelation 8:7.
