Revelation 18:15

The merchants of these things, who became rich by her
Her lusting after luxuries provided the stream of revenue by which the merchants became rich (Rev. Rev. 18:3+, Rev. 18:11+).

will stand at a distance for fear of her torment, weeping and wailing
The merchants have no heartfelt pity over the city and her destruction. Their concern and lamentation derives entirely from their own self-interest. Their self-preservation explains both their standing at a distance and their lamentation. For it is their loss of revenue and commercial exchange which causes their sorrow, not the countless lives or devastation associated with the fall of the city. “Your merchants from your youth; they shall wander each one to his quarter. No one shall save you” (Isa. Isa. 47:15).
