Eclesiastés 1

And I have dedicated my heart, so that I may know prudence and doctrine, and also error and foolishness. Yet I recognize that, in these things also, there is hardship, and affliction of the spirit.

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.
