'Benefit' in the Bible

What benefit do people get from all the effort which they expend on earth?

So I decided to discern the benefit of wisdom and knowledge over foolish behavior and ideas; however, I concluded that even this endeavor is like trying to chase the wind!

What benefit does the worker gain from what he undertakes?

And I have seen all the labour, and all the benefit of the work, because for it a man is the envy of his neighbour. Even this is vanity and vexation of spirit.

Two people are better than one, because they can reap more benefit from their labor.

In the multiplying of good have its consumers been multiplied, and what benefit is to its possessor except the sight of his eyes?

Because many words lead to pointlessness, how do people benefit from this? 12Who knows what is best for people in this life, every day of their pointless lives that they pass through like a shadow? Who informs people on earth what will come along after them?

Wise use of possessions is good; it brings benefit to the living.
