4 Generations come and generations go, but the earth remains forever.

Matthew Henry's Commentary on Ecclesiastes 1:4

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.
