NET
17 So I loathed life because what happens on earth seems awful to me; for all the benefits of wisdom are futile—like chasing the wind.
Darby
17 And I hated life; for the work that is wrought under the sun was grievous unto me; for all is vanity and pursuit of the wind.
KJV
17 Therefore I hated life; because the work that is wrought under the sun [is] grievous unto me: for all [is] vanity and vexation of spirit.
