Ecclesiastes 2:19; Ecclesiastes 2:23

Ecclesiastes 2:19

19 And who knows whether that person will be wise or foolish? 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.

Ecclesiastes 2:23

23 All their days their work is grief and pain; even at night their minds do not rest. This too is meaningless.
