Isaiah 57:20

But the wicked are like the troubled sea, when it cannot rest,.... Disturbed by winds, storms, and hurricanes, when its waves rise, rage, and tumble about, and beat against the shore and sand, threatening to pass the bounds fixed for it. In such like agitations will the minds of wicked men be, through the terrors of conscience for their sins; or through the malice and envy in them at the happiness and prosperity of the righteous, now enjoyed, upon the downfall of antichrist; and through the judgments of God upon them, gnawing their tongues for pain, and blaspheming the God of heaven, because of their plagues and pains, Revelation 16:9:

whose waters cast up mire and dirt; from the bottom of the sea upon the shore; so the hearts of wicked men, having nothing but the mire and dirt of sin in them, cast out nothing else but the froth and foam of their own shame, blasphemy against God, and malice against his people.
