'Muddied' in the Bible

A righteous person who yields to the wickedis like a muddied spring or a polluted well.

“Son of man, take up a lamentation over Pharaoh king of Egypt and say to him,‘You compared yourself to a young lion of the nations,Yet you are like the monster in the seas;And you burst forth in your riversAnd muddied the waters with your feetAnd fouled their rivers.’”

Yet My flock has to feed on what your feet have trampled, and drink what your feet have muddied.
