BBE(i)
20 So my mind was turned to grief for all the trouble I had taken and all my wisdom under the sun.
21 Because there is a man whose work has been done with wisdom, with knowledge, and with an expert hand; but one who has done nothing for it will have it for his heritage. This again is to no purpose and a great evil.
22 What does a man get for all his work, and for the weight of care with which he has done his work under the sun?
23 All his days are sorrow, and his work is full of grief. Even in the night his heart has no rest. This again is to no purpose.
