Kohelet 2:10-12

Orthodox Jewish Bible

¹⁰ And whatsoever mine eyes desired I kept not from them, I withheld not my lev from any simchah; for my lev rejoiced in all my amal (labor); and this was my chelek (portion) for all my amal.

¹¹ Then I looked on kol ma’asim that my hands had wrought, and on the amal that I had labored to do; and, hinei, all was hevel and chasing after ruach, and there was no profit under the shemesh.

¹² And I turned myself to consider chochmah, and holelot, and sichlut; for what can the adam do who cometh after HaMelech? Even that which hath been done already.
