16When I applied my mind to know wisdom and to observe the task that one performs on the earth— though his eyes do not see sleep in the day or even in the night —
17I saw every work of God, and that a man is unable to comprehend the work that is done under the sun. Despite his efforts to search it out, he cannot find its meaning; even if the wise man claims to know, he is unable to comprehend.
— Ecclesiastes 8:16-17
