For he saith to the snow. — All the operations of nature obey the behest of God — the snow, the gentle showers, the drenching downpour. By means of these He sealeth up the hand of every man, obstructing and impeding their works and movements, so that all the men whom He has made may know it or know Him. This is the plain meaning, which the Authorised Version gives somewhat less clearly. Men may learn from these things that they and their works are under the control of God. They are not the entirely free agents they suppose.
