Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun.

So my mind was turned to grief for all the trouble I had taken and all my wisdom under the sun.

Οθεν εγω στραφεις απηλπισα την καρδιαν μου περι παντος του μοχθου, τον οποιον εμοχθησα υπο τον ηλιον.

Therefore I went about to cause my heart to despair of all the labour which I took under the sun.
