Ecclesiastes 2:21-23

The Vanity of Toil

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 _c all the toil and striving of heart with which he toils beneath the sun? ²³ For _d all his days are full of sorrow, and his _e work is a vexation. Even in the night his heart does not rest. This also is vanity.
