3 For all the nations have drunk of the wine of the wrath of her sexual immorality, the kings of the earth committed sexual immorality with her, and the merchants of the earth grew rich from the abundance of her luxury.”
all the nations have drunk the wine of her immorality – taking the cup of the Lord without discernment (1 Cor 11:27), this becomes the “wine of God’s wrath,” as in Rev 14:10.
the merchants rich – see verse 11.
