Ecclesiastes 2:18-20

New International Version

¹⁸ I hated all the things I had toiled for under the sun, because I must leave them to the one who comes after me.^{(A) 19} And who knows whether that person will be wise or foolish?^(B) Yet they will have control over all the fruit of my toil into which I have poured my effort and skill under the sun. This too is meaningless. ²⁰ So my heart began to despair over all my toilsome labor under the sun.
