Revelation 18:20 in the King James Version of the Bible, reads: "Rejoice over her, thou heaven, and ye holy apostles and prophets; for God hath avenged you on her." This verse occurs in the context of John's vision of the fall of Babylon the Great, the symbolic representation of the world system that opposes God. Throughout the book of Revelation, Babylon is presented as a powerful and influential force that opposes God and seeks to persecute and oppress his followers. This verse reflects the response of heaven, the holy apostles, and prophets to the fall of Babylon and the judgement of God upon her.

The theme of judgement is central to this verse. The fall of Babylon represents the ultimate judgement of God upon the forces of evil and those who oppose him. The call to "rejoice over her" reflects the celebration of this final victory and the defeat of the enemy. It symbolizes the triumph of righteousness over wickedness and the establishment of God's kingdom. This theme of judgement and victory is a common thread throughout the book of Revelation, as it reassures believers that ultimately, God will triumph over evil and that justice will be served.

The reference to heaven, the holy apostles, and prophets underscores the significance of this event. The heavenly realm rejoices over the judgement of Babylon, indicating the universal impact and significance of this event. The inclusion of the holy apostles and prophets further emphasizes the importance of this judgement in the divine plan of redemption and restoration. It is a momentous occasion that elicits a response of joy and celebration from all who are aligned with God and his purposes.

The language used in this verse also conveys a sense of retribution and vindication. The expression "for God hath avenged you on her" suggests that the judgement of Babylon is the fulfillment of God's promise to avenge his people and right the wrongs perpetrated against them. This language conveys a sense of justice and recompense, assuring believers that God will not overlook the sufferings and persecutions they have endured. It also serves as a source of comfort and encouragement, reminding believers that God is ultimately in control and will bring about justice in his perfect timing.
