The waters wear the stones. The power of the soft element of water, by continual washing or dripping, to wear away the hardest stone, has often been noticed, and is a frequent topic in poetry. Deep ravines have been worn in course of time, through broad and lofty mountain ranges by rivers, the stone yielding little by little to the action of the water, until at last a broad chasm is made.
So the continual wearing action of calamity often lays low the prosperous. Thou washest away the things which grow out of the dust of the earth; rather, as in the Revised Version, the overflowings thereof wash away the dust of the earth; i.
e. "overflows of water, inundations, floods, not only make a way through rocks, but often carry off great tracts of rich soil, hurrying the alluvium down to the sea, and leaving in its place a marsh or a waste."
And thou destroyest the hope of man. Even thus from time to time does God ruin and destroy the hopes of a prosperous man.
