Kohelet 2:21-23

Orthodox Jewish Bible

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?

²³ For all his yamim are machovim (sorrows), and his travail ka’as (grief, vexation); yea, his lev taketh not rest balailah. This also is hevel.
