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

And I gave my heart to getting knowledge of wisdom, and of the ways of the foolish. And I saw that this again was desire for wind.

Και εδωκα την καρδιαν μου εις το να γνωριση σοφιαν και εις το να γνωριση ανοησιαν και αφροσυνην· πλην εγνωρισα οτι και τουτο ειναι θλιψις πνευματος.

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