I set my heart to seek and to investigate with wisdom everything that is done under heaven. It is a burdensome task that God has given to humanity to be occupied with.
There is a person who is alone, having neither son nor brother; there is not an end to all his toil, and his eyes are not satisfied with riches. He asks, “For whom do I labor and cause my life to lack good things?” This also is vanity and a burdensome task.
And I turned my heart to know and seek and search out wisdom in the scheme of things and to know the wickedness of folly, and that foolishness is madness.
