Ecclesiastes 2:21-23

New Living Translation

²¹ Some people work wisely with knowledge and skill, then must leave the fruit of their efforts to someone who hasn’t worked for it. This, too, is meaningless, a great tragedy. ²² So what do people get in this life for all their hard work and anxiety? ²³ Their days of labor are filled with pain and grief; even at night their minds cannot rest. It is all meaningless.
