5 The sun rises and the sun goes down, and hurries to the place where it rises. 6 The wind blows to the south, and goes around to the north; round and round goes the wind, and on its circuits the wind returns. 7 All streams run to the sea, but the sea is not full; to the place where the streams flow, there they continue to flow.
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.
