23. How does the voice out of heaven emphasize the urgency of fleeing out of Babylon the Great?

²³ Is it really so urgent to flee out of Babylon the Great, withdrawing from membership in the world’s religions and making a complete separation? It is, for we need to take God’s view of this age-old religious monstrosity, Babylon the Great. He did not mince words in calling her the great harlot. So now the voice out of heaven informs John further concerning this whore: “For her sins have massed together clear up to heaven, and God has called her acts of injustice to mind. Render to her even as she herself rendered, and do to her twice as much, yes, twice the number of the things she did; in the cup in which she put a mixture put twice as much of the mixture for her. To the extent that she glorified herself and lived in shameless luxury, to that extent give her torment and mourning. For in her heart she keeps saying, ‘I sit a queen, and I am no widow, and I shall never see mourning.’ That is why in one day her plagues will come, death and mourning and famine, and she will be completely burned with fire, because Jehovah God, who judged her, is strong.”​—Revelation 18:5-8.

27. What parallels are there between the judgments on ancient Babylon and those on Babylon the Great?

²⁷ Ancient Babylon’s fall and eventual desolation was a punishment for her sins. “For clear to the heavens her judgment has reached.” (Jeremiah 51:9) Similarly, the sins of Babylon the Great have “massed together clear up to heaven,” so as to come to the attention of Jehovah himself. She is guilty of injustice, idolatry, immorality, oppression, robbery, and murder. Ancient Babylon’s fall was, in part, vengeance for what she had done to Jehovah’s temple and his true worshippers. (Jeremiah 50:8, 14; 51:11, 35, 36) The fall of Babylon the Great and her eventual destruction are likewise expressions of vengeance for what she has done to true worshippers over the centuries. Indeed, her final destruction is the beginning of “the day of vengeance on the part of our God.”​—Isaiah 34:8-10; 61:2; Jeremiah 50:28.

28. What standard of justice does Jehovah apply to Babylon the Great, and why?

²⁸ Under the Mosaic Law, if an Israelite stole from his fellow countrymen, he had to pay back at least double in compensation. (Exodus 22:1, 4, 7, 9) In the coming destruction of Babylon the Great, Jehovah will apply a comparable standard of justice. She is to receive twice as much as she gave out. There will be no mercy shown because Babylon the Great has shown no mercy to her victims. She fed parasitically on the peoples of the earth to keep herself in “shameless luxury.” Now she will experience suffering and mourning. Ancient Babylon felt that she was in an absolutely secure position, boasting: “I shall not sit as a widow, and I shall not know the loss of children.” (Isaiah 47:8, 9, 11) Babylon the Great also feels secure. But her destruction, decreed by Jehovah who “is strong,” will happen quickly, as if “in one day”!
