5 The sun comes up and the sun goes down, and goes quickly back to the place where he came up. 6 The wind goes to the south, turning back again to the north; circling round for ever. 7 All the rivers go down to the sea, but the sea is not full; to the place where the rivers go, there 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.
