Revelation 18:20: Rejoice over her, thou heaven, and ye holy apostles and prophets; for God hath avenged you on her.

Three groups of wicked people will mourn when Babylon falls in a single day,¹ but the righteous angels in heaven² will rejoice.³ In fact, God the Father⁴ commands this heavenly host⁵ to rejoice over Babylon's ruin.⁶ John saw and heard them rejoice in Revelation 19:1-4.⁷

The heavenly host consists of the 144,000 Servants that will stand with Christ on heavenly mount Zion at the Second Coming.⁸ John divides them into three representative groups⁹ that include holy saints,¹⁰ apostles,¹¹ and prophets.¹² The three representative groups symbolically mirror the three opposite representative groups of mourners in Modern Babylon that include the kings of the earth,¹³ the merchants,¹⁴ and the mariners.¹⁵ The saints in heaven, and ye holy apostles and prophets represent all the victims¹⁶ of Babylon on earth.¹⁷ When Babylon falls, these victims from all ages will be vindicated.¹⁸ John saw that God hath avenged¹⁹ these victims with the same judgments that Babylon inflicted on them.²⁰ His vision is similar to Jeremiah's vision, which predicted that the judgments of Babylon would reach heaven.²¹
