Isaiah 17:12

Woe to the multitude of many people, with the turmoil and tumult of their advance, which make a noise like the noise of the seas; and to the rushing of nations, that make a rushing like the rushing of mighty waters! The enemies of Israel, who are also types of the enemies of the Church, are pictured as being in a state of seething unrest, anxiously striving to harm the Lord's people.
