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.
By the sweat of your face you will eat bread until you return to the ground, because out of it you were taken; for you are dust, and to dust you will return.”
Just as you do not know the path of the wind, or how the bones grow to fullness in the womb of a woman with child; so you do not know the work of God who makes everything.
To the person who is pleasing before Him, God gives wisdom, knowledge, and joy, but to the one who sins, He gives the task to gather and collect, to give to the other person who is pleasing before God. This also is vanity and a chasing after wind.
He has made everything beautiful in its time. He has also put obscurity in their hearts so that people do not come to know the work that God has done from the beginning to the end.
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.
