Charles H. Spurgeon on Psalms 33:7

He gathereth the waters of the sea together as an heap, etc. "God called the gathering together of the waters, seas." Ge 1:10. This unstable element must, like all other elements, be put under law, and confined within bounds, that there might be a habitable earth for man and all the creatures around him. Thus the psalmist sings, He gathereth the waters of the sea together as an heap: he layeth up the depth in storehouses. The boundary was such as to cause his servants to wonder. They looked from the shore, as we do, and under the influence of a well known law, the billows in their heaving swells, seemed as if they would, as if they did, touch the sky itself; and as if they were so much higher than the shore, that they were in danger of leaving their basin and stretching over the land. Just such an impression, we with all our science, popularly hold. The prophets thus looked as we do, and under the same kind of feeling. How wonderful, they thought, is all this! A low barrier of sand is made Jehovah's agent for bounding the deep. "The Lord hath placed the sand for the bound of the sea by a perpetual decree, that it cannot pass it: and though the waves thereof toss themselves, yet they not prevail; though they roar, yet can they not pass over it." Jer 5:22. John Duns, D.D., in "Science and Christian Thought, "1868.
