Babylon was the unstoppable death of many Old Testament nations. You know how you read in Exodus, Joshua and elsewhere about these “Tites” and those “Tites” and those “Vites” and so forth, then they all suddenly disappear by the time Jesus shows up in Matthew? Well, besides there being hundreds of years in between, Babylon is mainly responsible for wiping them all out. And just think; that’s only the first of four empires to remodel the Old Testament world. That’s why things are so different in the New Testament.
