Shall they therefore empty their net, and not spare continually to slay the nations? And not spare continually to slay the nation? - They are running from conquest to conquest; burning, slaying, sacking, and slaughtering. Like the fishermen, who throw cast after cast while any fish are to be caught, so Nebuchadnezzar is destroying one nation after another. This last sentence explains the allegory of the net.
