'Anything' in the Bible

Listen to this, you elders; pay attention, all inhabitants of the land. Has anything like this ever happened in your whole life or in the lifetime of your ancestors?

It will be a day of dreadful darkness, a day of foreboding storm clouds, like blackness spread over the mountains. It is a huge and powerful army -- there has never been anything like it ever before, and there will not be anything like it for many generations to come!
