There will be a war in the future between the Egyptians and the Babylonians. The Ethiopians, Libyans and Lydians will be involved. The swords will get drunk on the blood they spill. In the end, the Babylonians will win.
God is coming for the Philistines' and the Ashkelonites' hair.
God is going to make the Moabites vomit to death while the other nations laugh. He's going to do a lot of other stuff as well, but I think we're all familiar with the diatribe by now. However, he'll restore them in the end.
God still isn't done. He has more death and destruction in store for the Ammonites and the Edomites and a bunch more cities and nations. And even though he's been dead for a long time and even though Ecclesiastes just told us the dead don't know anything, god is going to uncover his secret places and kill off all his children. He also brings up Sodom and Gomorrah. It's almost like these books were written independently at different times and only brought together later.
