Ecclesiastes 2:18-20

Darby Translation

¹⁸ And I hated all my labour wherewith I had been toiling under the sun, because I should leave it unto the man that shall be after me.

¹⁹ And who knoweth whether he will be a wise [man] or a fool? yet shall he have rule over all my labour at which I have laboured, and wherein I have been wise under the sun. This also is vanity.

²⁰ Then I went about to cause my heart to despair of all the labour wherewith I had laboured under the sun.
