I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold of folly, until I might see what it was good for the sons of men that they should do under heaven all the days of their lives.
For that which happens to the sons of men happens to animals. Even one thing happens to them. As the one dies, so the other dies. Yes, they have all one breath; and man has no advantage over the animals: for all is vanity.
When I applied my heart to know wisdom, and to see the business that is done on the earth (for also there is that neither day nor night sees sleep with his eyes),
This is an evil in all that is done under the sun, that there is one event to all: yes also, the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead.
