5 Also, the sun hath risen, and the sun hath gone in, and unto its place panting it is rising there. 6 Going unto the south, and turning round unto the north, turning round, turning round, the wind is going, and by its circuits the wind hath returned. 7 All the streams are going unto the sea, and the sea is not full; unto a place whither the streams are going, thither they are turning back to go.
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.
