Ecclesiastes 8:17
World English Bible British Edition · Berean Standard Bible
then 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.
I 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.
