Eclesiastés 1

Mais ayant appliqué mon cœur à discerner ce qui est sagesse, et à discerner ce qui est folie, je reconnus que cela aussi est un effort stérile.

Y dí mi corazón á conocer la sabiduría, y también á entender las locuras y los desvaríos: conocí que aun esto era aflicción de espíritu.

And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.
