Kohelet 2:20-22

Orthodox Jewish Bible

²⁰ Therefore I turned aside to give up my lev to despair over all the wearisome amal with which I toiled under the shemesh.

²¹ For there is an adam whose amal is with chochmah, and da’as, and kishron (skill); yet to an adam that hath not worked for it he must leave it for his chelek. This also is hevel and a ra’ah rabbah.

²² For what hath adam for all his amal, and for all the striving of his lev, wherein he hath labored under the shemesh?
