Ecclesiastes 5:14-16

5:14 Then that wealth was lost through bad luck;

although he fathered a son, he has nothing left to give him.

5:15 Just as he came forth from his mother's womb, naked will he return as he came,

and he will take nothing in his hand that he may carry away from his toil.

5:16 This is another misfortune:

Just as he came, so will he go.

What did he gain from toiling for the wind?
