'Roaring' in the Bible

And he knew their desolate palaces, and he laid waste their cities; and the land was desolate, and the fulness thereof, by the noise of his roaring.

There is a conspiracy of her prophets in the midst thereof, like a roaring lion ravening the prey; they have devoured souls; they have taken the treasure and precious things; they have made her many widows in the midst thereof.
