6 Reward her even as she rewarded you, and double unto her double according to her works: in the cup which she hath filled fill to her double.
6 Give back to her as she has given; pay her back double for what she has done. Pour her a double portion from her own cup.
6 Pay her back as she herself has paid back others, and repay her double for her deeds; mix a double portion for her in the cup she mixed.
6 Give her back what she's given, double what she's doubled in her works, double the recipe in the cup she mixed;
6 Render to her just as she rendered to you, and repay her double according to her works; in the cup which she has mixed, mix double for her.
6 Do to her as she has done to others. Double her penalty for all her evil deeds. She brewed a cup of terror for others, so brew twice as much for her.
Matthew Henry's Commentary on Revelation 18:6
Commentary on Revelation 18:1-8
(Read Revelation 18:1-8)
The downfal and destruction of the mystical Babylon are determined in the counsels of God. Another angel comes from heaven. This seems to be Christ himself, coming to destroy his enemies, and to shed abroad the light of his gospel through all nations. The wickedness of this Babylon was very great; she had forsaken the true God, and set up idols, and had drawn all sorts of men into spiritual adultery, and by her wealth and luxury kept them in her interest. The spiritual merchandise, by which multitudes have wickedly lived in wealth, by the sins and follies of mankind, seems principally intended. Fair warning is given to all that expect mercy from God, that they should not only come out of this Babylon, but assist in her destruction. God may have a people even in Babylon. But God's people shall be called out of Babylon, and called effectually, while those that partake with wicked men in their sins, must receive of their plagues.
