For who [limited by human wisdom] knows what is good for man during his lifetime, during the few days of his futile life? He spends them like a shadow [staying busy, but achieving nothing of lasting value].

The heart of the wise is in the house of mourning, but the heart of fools is in the house of merrymaking.

It is better to go to a house of mourning
than to go to a house of feasting,
since that is the end of all mankind,
and the living should take it to heart.
