Kohelet 1:2-3

2 Hevel havalim, saith Kohelet, hevel havalim; all is hevel.

3 What profit hath a man from all his amal (toil) which he hath toiled under the shemesh?

Kohelet 1:14

14 I have seen all the ma’asim that are done under the shemesh; and, hinei, all is hevel and chasing after ruach (wind).

Kohelet 1:17

17 And I applied my lev to have da’as of chochmah, and to have da’as of holelot (madness) and sichlut (folly); I perceived that this also is striving after ruach (wind).
