Ecclesiastes 2:18-19

NHEB(i) 18 I hated all my labor in which I labored under the sun, seeing that I must leave it to the man who comes after me. 19 Who knows whether he will be a wise man or a fool? Yet he will have rule over all of my labor in which I have labored, and in which I have shown myself wise under the sun. This also is vanity.
