John sees the Lamb standing on Mount Zion and with him 144,000 who have the Lamb's name and his Father's name written on their foreheads. A voice from heaven like the roar of many waters is heard, and they sing a new song before the throne that no one could learn except the 144,000, those redeemed from the earth. They are described as those who have not defiled themselves, who follow the Lamb wherever he goes, who were purchased as firstfruits for God and in whose mouth no lie was found (vv. 1-5).
A first angel flies in midheaven with the eternal gospel to proclaim to every nation, tribe, language and people that they should fear God and give him glory, because the hour of his judgment has come. A second angel announces that Babylon the great has fallen. A third warns that anyone who worships the beast and its image and receives its mark will drink the wine of God's wrath and be tormented. A call follows for the endurance of the saints who keep the commandments of God and their faith in Jesus (vv. 6-12).
A voice from heaven tells John to write: blessed are the dead who from now on die in the Lord, for they rest from their labors and their deeds follow them. Then John sees a white cloud and seated on it one like a son of man with a golden crown and a sharp sickle. An angel comes out of the temple and tells him to use the sickle, because the harvest of the earth is ripe, and the earth is reaped (vv. 13-16).
Another angel comes out of the temple with a sharp sickle, and another, who has authority over fire, tells him to gather the clusters of the vine of the earth. The angel throws the harvest into the great winepress of God's wrath, which is trodden outside the city, and blood flows from it as high as the horses' bridles for 1,600 stadia (vv. 17-20).
