'Concluded' in the Bible

I decided to carefully and thoroughly examine all that has been accomplished on earth. I concluded: God has given people a burdensome task that keeps them occupied.

I reflected on everything that is accomplished by man on earth, and I concluded: Everything he has accomplished is futile -- like chasing the wind!

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!

Yet when I reflected on everything I had accomplished and on all the effort that I had expended to accomplish it, I concluded: "All these achievements and possessions are ultimately profitless -- like chasing the wind! There is nothing gained from them on earth."

I concluded that wisdom is more useful than foolishness, just as light is more useful than darkness.

I have concluded that the only worthwhile thing for them is to take pleasure in doing good in life;

I have concluded that everything that God undertakes will last for eternity nothing can be added to it nor taken away from it and that God acts this way so that people will fear him.

I concluded that it is worthwhile for people to find joy in their accomplishments, because that is their inheritance, since who can see what will exist after them?

Here is a pointless thing that happens on earth: A righteous man receives what happens to the wicked, and a wicked man receives what happens to the righteous. I concluded that this, too, is pointless.

I observed all the work of God and concluded that man is unable to discover the work that is done under the sun. Even though a man labors hard to explore it, he cannot find it; even if the wise man claims to know it, he is unable to discover it.

So I reflected on all this, attempting to clear it all up. I concluded that the righteous and the wise, as well as their works, are in the hand of God; whether a person will be loved or hated -- no one knows what lies ahead.

So I concluded, "Wisdom is better than strength. Nevertheless, the wisdom of the poor is rejected his words are never heard."
