The noise of their waves, when the sea is tempestuous, and threatens to swallow up ships and men that are in it, or to overflow the earth. And the tumult of the people; and as he stills the natural, so also he quiets the metaphorical seas, tumultuous and unruly people; for multitudes of people are oft called seas in prophetical writings, as Isaiah 17:12,13 Jer 51:42 Revelation 17:15.
