Ecclesiastes 2:3

2:3 I thought deeply about the effects of indulging myself with wine

(all the while my mind was guiding me with wisdom)

and the effects of behaving foolishly,

so that I might discover what is profitable

for people to do on earth during the few days of their lives.

Ecclesiastes 9:3

9:3 This is the unfortunate fact about everything that happens on earth:

the same fate awaits everyone.

In addition to this, the hearts of all people are full of evil,

and there is folly in their hearts during their lives – then they die.
