15 And another angel came out of the temple, calling with a loud voice to him who sat on the cloud, "Put in your sickle, and reap, for the hour to reap has come, for the harvest of the earth is fully ripe." 16 So he who sat on the cloud swung his sickle across the earth, and the earth was reaped. 17 Then another angel came out of the temple in heaven, and he too had a sharp sickle. 18 And another angel came out from the altar, the angel who has authority over the fire, and he called with a loud voice to the one who had the sharp sickle, "Put in your sickle and gather the clusters from the vine of the earth, for its grapes are ripe." 19 So the angel swung his sickle across the earth and gathered the grape harvest of the earth and threw it into the great winepress of the wrath of God.

Commentary on Revelation 14:14-20
(Read Revelation 14:14-20)
Warnings and judgments not having produced reformation, the sins of the nations are filled up, and they become ripe for judgments, represented by a harvest, an emblem which is used to signify the gathering of the righteous, when ripe for heaven, by the mercy of God. The harvest time is when the corn is ripe; when the believers are ripe for heaven, then the wheat of the earth shall be gathered into Christ's garner. And by a vintage. The enemies of Christ and his church are not destroyed, till by their sin they are ripe for ruin, and then he will spare them no longer. The wine-press is the wrath of God, some terrible calamity, probably the sword, shedding the blood of the wicked. The patience of God towards sinners, is the greatest miracle in the world; but, though lasting, it will not be everlasting; and ripeness in sin is a sure proof of judgment at hand.
