'Roaring' in the Bible

‘He destroyed their palacesAnd he flattened their cities;And the land and all who were in it were appalledBy the sound of his roaring.

There is a conspiracy of her [false] prophets in her midst, like a roaring lion tearing the prey. They have devoured [human] life; they have taken [in their greed] treasure and precious things; they have made many widows among her.
