18:20-24 That which is matter of rejoicing to the servants of God on earth, is matter of rejoicing to the angels in heaven. The apostles, who are honoured and daily worshipped at Rome in an idolatrous manner, will rejoice in her fall. The fall of Babylon was an act of God's justice. And because it was a final ruin, this enemy should never molest them any more; of this they were assured by a sign. Let us take warning from the things which brought others to destruction, and let us set our affections on things above, when we consider the changeable nature of earthly things.
23. What a blessed contrast is Re 22:5, respecting the city of God: "They need no candle (just as Babylon shall no more have the light of a candle, but for a widely different reason), for the Lord God giveth them light."
candle—Translate as Greek, "lamp."
bridegroom … bride … no more … in thee—Contrast the heavenly city, with its Bridegroom, Bride, and blessed marriage supper (Re 19:7, 9; 21:2, 9; Isa 62:4, 5).
thy merchants were—So most of the best authorities read. But A omits the Greek article before "merchants," and then translates, "The great men of … were thy merchants."
