5 The sun also ariseth, and the sun goeth down, and hasteth to its place where it ariseth. 6 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. 7 All the rivers run into the sea, yet the sea is not full; unto the place whither the rivers go, thither they go again.
Matthew Henry's Commentary on Ecclesiastes 1:5-7
Commentary on Ecclesiastes 1:4-8
(Read Ecclesiastes 1:4-8)
All things change, and never rest. Man, after all his labour, is no nearer finding rest than the sun, the wind, or the current of the river. His soul will find no rest, if he has it not from God. The senses are soon tired, yet still craving what is untried.
