When there is a man who has labored with wisdom, knowledge, and skill, and he must give his portion to a man who has not worked for it, this too is futile and a great evil.

Psalm 49:10
For it is clear that wise men die, and the foolish and the senseless both perish and leave their wealth to others.

Ecclesiastes 2:18
I hated all for which I had toiled under the sun, because I must leave it to the man who comes after me.

Ecclesiastes 2:20
So my heart began to despair over all the labor that I had done under the sun.

Ecclesiastes 4:4
I saw that all labor and success spring from a man's envy of his neighbor. This too is futile and a pursuit of the wind.

Ecclesiastes 4:8
There is a man all alone, without even a son or brother. And though there is no end to his labor, his eyes are still not content with his wealth: "For whom do I toil and bereave my soul of enjoyment?" This too is futile--a miserable task.

For there is a man whose labor is in wisdom, and in knowledge, and in equity; yet to a man that has not labored therein shall he leave it for his portion. This also is vanity and a great evil.
