Which stilleth the noise of the seas, the noise of their waves,.... By a word speaking; as our Lord did when here on earth, and which was a proof and evidence of his eternal power and Godhead. These figurative expressions are interpreted by the next clause; and the tumult of the people: of wicked men, who foam and rage against the people of God, and are like a troubled sea that cannot rest; but God can say to these proud waters, which threaten to go over their souls, Peace, be still; he can stop their opposition, quell their insurrections, restrain their wrath, and make them peaceable and quiet; wherefore the saints have no reason to be afraid of them, Psa 46:2.
