'Churn' in the Bible

“Son of man, lament for Pharaoh king of Egypt and say to him:You compare yourself to a lion of the nations,but you are like a monster in the seas.You thrash about in your rivers,churn up the waters with your feet,and muddy the rivers.”

I will slaughter all its cattlethat are beside many waters.No human foot will churn them again,and no cattle hooves will disturb them.
