Ecclesiastes 8:16-17

¹⁶When I applied my heart to know wisdom, and to see the business that is done on the earth (even though eyes see no sleep day or night),

¹⁷then I saw all the work of God, that man can’t find out the work that is done under the sun, because however much a man labours to seek it out, yet he won’t find it. Yes even though a wise man thinks he can comprehend it, he won’t be able to find it.
