18 I hated all my toil in which I toil under the sun, seeing that I must ^oleave it to the man who will come after me, 19 and who knows whether he will be wise or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity. 20 So I turned about and gave my heart up to despair over all the toil of my labors under the sun, 21 because sometimes a person who has toiled with wisdom and knowledge and skill must leave everything to be enjoyed by someone who did not toil for it. This also is vanity and a great evil. 22 What has a man from all the ^ptoil and striving of heart with which he toils beneath the sun? 23 For ^qall his days are full of sorrow, and his work is a vexation. Even in the night his heart does not rest. This also is vanity.
