Albert Barnes Commentary Revelation 18:15

"The merchants of these things, who were made rich by her, shall stand afar off for the fear of her torment, weeping and mourning;" — Revelation 18:15 (ASV)

The merchants of these things. They trafficked in these things and supplied the city with them (Revelation 18:11).

Which were made rich by her. By traffic with her.

Shall stand afar off (Revelation 18:10).

For fear of her torment. Struck with terror by her torment, so that they did not dare to approach her (Revelation 18:10).
