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.

The connection is: Individual men are continually changing, while the succession of the race continues; just as the sun, wind, and rivers are ever shifting about, while the cycle in which they move is invariable; they return to the point whence they set out. Hence is man, as in these objects of nature which are his analogue, with all the seeming changes "there is no new thing" (Ec 1:9).
