'Trouble' in the Bible

“Son of man, take up a dirge (funeral poem to be sung) over Pharaoh king of Egypt and say to him,‘You have compared yourself to a young lion among the nations,But you are like a monster in the seas;You burst into your riversAnd disturbed and muddied the waters with your feetAnd fouled their rivers [the source of their prosperity].’”

I will also put fear into the hearts of many peoples when I bring your destruction [and captivity] among the nations, into countries which you have not known.

“I will also destroy all its cattle from beside its great waters;And the foot of man will not muddy them anymoreNor will the hoofs of the animals muddy them.
