1:9-11 Men's hearts and their corruptions are the same now as in former times; their desires, and pursuits, and complaints, still the same. This should take us from expecting happiness in the creature, and quicken us to seek eternal blessings. How many things and persons in Solomon's day were thought very great, yet there is no remembrance of them now!
9. Rather, "no new thing at all"; as in Nu 11:6. This is not meant in a general sense; but there is no new source of happiness (the subject in question) which can be devised; the same round of petty pleasures, cares, business, study, wars, &c., being repeated over and over again [Holden].
