17 Then the seventh angel poured out his bowl into the air, and a loud voice came out of the temple of heaven, from the throne, saying, "It is done!" 18 And there were noises and thunderings and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth. 19 Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath. 20 Then every island fled away, and the mountains were not found. 21 And great hail from heaven fell upon men, each hailstone about the weight of a talent. Men blasphemed God because of the plague of the hail, since that plague was exceedingly great.

Commentary on Revelation 16:17-21

(Read Revelation 16:17-21)

The seventh and last angel poured forth his vial, and the downfal of Babylon was finished. The church triumphant in heaven saw it and rejoiced; the church in conflict on earth saw it and became triumphant. God remembered the great and wicked city; though for some time he seemed to have forgotten her idolatry and cruelty. All that was most secure was carried away by the ruin. Men blasphemed: the greatest judgments that can befal men, will not bring to repentance without the grace of God. To be hardened against God, by his righteous judgments, is a certain token of sure and utter destruction.
