Ecclesiastes 1:3-7

What profit hath man of all his labor wherein he laboreth under the sun? One generation goeth, and another generation cometh; but the earth abideth for ever. The sun also ariseth, and the sun goeth down, and hasteth to its place where it ariseth. The wind goeth toward the south, and turneth about unto the north; it turneth about continually in its course, and the wind returneth again to its circuits. All the rivers run into the sea, yet the sea is not full; unto the place whither the rivers go, thither they go again.
