'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 have concluded that there is nothing better for people than to be happy and to enjoy themselves as long as they live,

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 that wisdom is better than might, but a poor man's wisdom is despised; no one ever listens to his advice.
