Which setteth fast the mountains That they are not overthrown by floods, or earthquakes, or other natural causes; which stability they have only from God's preserving providence, which alone sustains all persons and things; being girded with power Being able to do it, and that with infinite ease, having only to speak and it is done. Which stillest the noise of the sea When it is very tempestuous, and threatens to swallow up ships and men that are in it, or to overflow the earth. And the tumults of the people As he stills the natural, so he also quiets the metaphorical seas, tumultuous and unruly mobs and insurrections of people, often represented under this emblem in the prophetical writings.
