Revelation 18:9 And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning,
10 Standing afar off for the fear of her torment, saying, Alas, alas, that great city Babylon, that mighty city! for in one hour is thy judgment come.
11 And the merchants of the earth shall weep and mourn over her; for no man buyeth their merchandise any more:
12 The merchandise of gold, and silver, and precious stones, and of pearls, and fine linen, and purple, and silk, and scarlet, and all thyine wood, and all manner vessels of ivory, and all manner vessels of most precious wood, and of brass, and iron, and marble,
13 And cinnamon, and odours, and ointments, and frankincense, and wine, and oil, and fine flour, and wheat, and beasts, and sheep, and horses, and chariots, and slaves, and souls of men.
14 And the fruits that thy soul lusted after are departed from thee, and all things which were dainty and goodly are departed from thee, and thou shalt find them no more at all.
Now all the kings and leaders of the earth that were taking advantage of the people that worshiped the beast are beginning to mourn the the destruction of all the economic centers of the world. I believe that it makes reference to city Babylon as being destroyed but you have to realize everything that is happening is happening world wide so all economic centers are being destroyed. All these merchants are distancing themselves from these centers for fear of punishment of themselves. They are saddened by the fact they no longer have any more goods to sell because everything is destroyed .You have to realize a lot of this stuff is things people can do without but there is also destruction to life necessities, such as food and water. It was bad enough to have the mark of the beast to buy and sell but now there is nothing to buy and sell , which can also be attributed to all the destruction that has happened because of all plagues. We see all this as being in the end times but unless we as nation turn back to God we could see some of this happening before that trumpet blows.
