Rejoice over her, {12} thou heaven, and ye holy apostles and prophets; for God hath avenged you on her.

(12) The other consequence on the ruin of Babylon, is the exultation or rejoicing of the godly in heaven and in earth as was noted in this verse.

People's New Testament

18:20 Rejoice over her, thou heaven, and ye holy apostles and prophets. While there are mourners, another company is called upon to rejoice. She had exalted herself against God. All who have been for God, and who have suffered from her, are called to rejoice.

Wesley's Notes

18:20 Rejoice over her, thou heaven - That is, all the inhabitants of it; and more especially, ye saints; and among the saints still more eminently, ye apostles and prophets.

Jamieson-Fausset-Brown Bible Commentary

20. holy apostles-So C reads. But A, B, Vulgate, Syriac, Coptic, and Andreas read, "Ye saints and ye apostles."

avenged you on her-Greek, "judged your judgment on (literally, exacting it from) her." "There is more joy in heaven at the harlot's downfall than at that of the two beasts. For the most heinous of all sin is the sin of those who know God's word of grace, and keep it not. The worldliness of the Church is the most worldly of all worldliness. Hence, Babylon, in Revelation, has not only Israel's sins, but also the sins of the heathen; and John dwells longer on the abominations and judgments of the harlot than on those of the beast. The term 'harlot' describes the false Church's essential character. She retains her human shape as the woman, does not become a beast: she has the form of godliness, but denies its power. Her rightful lord and husband, Jehovah-Christ, and the joys and goods of His house, are no longer her all in all, but she runs after the visible and vain things of the world, in its manifold forms. The fullest form of her whoredom is, where the Church wishes to be itself a worldly power, uses politics and diplomacy, makes flesh her arm, uses unholy means for holy ends, spreads her dominion by sword or money, fascinates men by sensual ritualism, becomes 'mistress of ceremonies' to the dignitaries of the world, flatters prince or people, and like Israel, seeks the help of one world power against the danger threatening from another" [Auberlen]. Judgment, therefore, begins with the harlot, as in privileges the house of God.

Matthew Henry's Concise Commentary

18:20-24 That which is matter of rejoicing to the servants of God on earth, is matter of rejoicing to the angels in heaven. The apostles, who are honoured and daily worshipped at Rome in an idolatrous manner, will rejoice in her fall. The fall of Babylon was an act of God's justice. And because it was a final ruin, this enemy should never molest them any more; of this they were assured by a sign. Let us take warning from the things which brought others to destruction, and let us set our affections on things above, when we consider the changeable nature of earthly things.

Matthew Henry's Whole Bible Commentary

Verses 9-24

Here we have,

I. A doleful lamentation made by Babylon's friends for her fall; and here observe,

1. Who are the mourners, namely, those who had been bewitched by her fornication, those who had been sharers in her sensual pleasures, and those who had been gainers by her wealth and trade-the kings and the merchants of the earth: the kings of the earth, whom she had flattered into idolatry by allowing them to be arbitrary and tyrannical over their subjects, while they were obsequious to her; and the merchants, that is, those who trafficked with her for indulgences, pardons, dispensations, and preferments; these will mourn, because by this craft they got their wealth.

2. What was the manner of their mourning. (1.) They stood afar off, they durst not come nigh her. Even Babylon's friends will stand at a distance from her fall. Though they had been partakers with her in her sins, and in her sinful pleasures and profits, they were not willing to bear a share in her plagues. (2.) They made a grievous outcry: Alas! alas! that great city, Babylon, that mighty city! (3.) They wept, and cast dust upon their heads, v. 19. The pleasures of sin are but for a season, and they will end in dismal sorrow. All those who rejoice in the success of the church's enemies will share with them in their downfall; and those who have most indulged themselves in pride and pleasure are the least able to bear calamities; their sorrows will be as excessive as their pleasure and jollity were before.

3. What was the cause of their mourning; not their sin, but their punishment. They did not lament their fall into idolatry, and luxury, and persecution, but their fall into ruin-the loss of their traffic and of their wealth and power. The spirit of antichrist is a worldly spirit, and their sorrow is a mere worldly sorrow; they did not lament for the anger of God, that had now fallen upon them, but for the loss of their outward comfort. We have a large schedule and inventory of the wealth and merchandise of this city, all which was suddenly lost (v. 12, 13), and lost irrecoverably (v. 14): All things which were dainty and goodly have departed from thee, and thou shalt find them no more at all. The church of God may fall for a time, but she shall rise again; but the fall of Babylon will be an utter overthrow, like that of Sodom and Gomorrah. Godly sorrow is some support under affliction, but mere worldly sorrow adds to the calamity.

II. An account of the joy and triumph there was both in heaven and earth at the irrecoverable fall of Babylon: while her own people were bewailing her, the servants of God were called to rejoice over her, v. 20. Here observe, 1. How universal this joy would be: heaven and earth, angels and saints, would join in it; that which is matter of rejoicing to the servants of God in this world is matter of rejoicing to the angels in heaven. 2. How just and reasonable; and that, (1.) Because the fall of Babylon was an act of God's vindictive justice. God was then avenging his people's cause. They had committed their cause to him to whom vengeance belongs, and now the year of recompence had come for the controversies of Zion; and, though they did not take pleasure in the miseries of any, yet they had reason to rejoice in the discoveries of the glorious justice of God. (2.) Because it was an irrecoverable ruin. This enemy should never molest them any more, and of this they were assured by a remarkable token (v. 21): An angel from heaven took up a stone like a great millstone, and cast it into the sea, saying, "Thus shall Babylon be thrown down with violence, and be found no more at all; the place shall be no longer habitable by man, no work shall be done there, no comfort enjoyed, no light seen there, but utter darkness and desolation, as the reward of her great wickedness, first in deceiving the nations with her sorceries, and secondly in destroying and murdering those whom she could not deceive," v. 24. Such abominable sins deserved so great a ruin.
