Earth’s kings, merchants, and maritime traders mourned the loss of those cities.

Revelation 18:9-19

9 “The kings of the earth who have acted immorally with people of those cities and have lived with the people of those cities, doing just what they wanted to do, will weep and mourn [DOU] for them when they see the smoke of the fire that is burning those cities. 10 They will stand far away from those cities, because they will be afraid that they will suffer just like the people of those cities are suffering. They will say, ‘Terrible things will happen to the awesome and mighty cities represented by Babylon! God will punish them suddenly and swiftly [MTY]!’ 11 The merchants of the earth will weep and will mourn [DOU] for those cities, because no one will ever again buy the things that they have to sell to the people in those cities. 12-13 12-13They sell ornaments made of gold, silver, precious stones, and pearls. They sell expensive cloth made of fine linen and silk, expensive cloth that is dyed purple and crimson. They sell all kinds of rare wood, all kinds of items made of ivory, costly wood, bronze, iron, and marble. They sell cinnamon, spice, perfume, frankincense, wine, olive oil, fine flour, and grain. They sell cattle, sheep, horses, and chariots. They even sell human beings [SYN, DOU] to become slaves. 14 The merchants will say, ‘The good things you people longed to have are gone! All your luxurious and splendid [DOU] possessions have vanished!! They will be gone forever/You will never have them again [LIT]!’ 15 The merchants who sold these things and who had become rich by supplying them for those cities will stand far away, because they will be afraid that they will suffer just like the people of those cities are suffering. They will weep and mourn [DOU], 16 and they will say, ‘Terrible things [DOU] have happened to the awesome/great [MET] cities! They were like queens who dressed themselves in clothes made of [MTY] fine linen cloth and expensive cloth dyed purple and crimson, and who were adorned with gold, precious stones, and pearls. 17 But suddenly and swiftly [MTY] God has destroyed these expensive things.’ Every ship captain, all people who travel by ship, all ◄sailors/those who work on ships►, and all others who earn their living by traveling on the ocean will stand far away from those cities. 18 When they see the smoke of the fire that is burning those cities, they will shout, ‘No other cities have ever been so awesome!’ [RHQ] 19 They will throw dust on their heads to show that they are sad, and they will shout, weep, and mourn [DOU]. They will say, ‘Terrible things have happened to the awesome/great cities, the cities that made all people who own ships that sail on the ocean become rich by carrying their costly ◄things for them to sell/merchandise►! God has suddenly and swiftly destroyed [MTY] those cities!’”
