Ecclesiastes 2:21-23

New International Version - UK

²¹ For a person may labour with wisdom, knowledge and skill, and then they must leave all they own to another who has not toiled for it. This too is meaningless and a great misfortune. ²² What do people get for all the toil and anxious striving with which they labour under the sun? ²³ All their days their work is grief and pain; even at night their minds do not rest. This too is meaningless.
