Ecclesiastes 8:17
Brenton's English Septuagint · Berean Standard Bible
And I beheld all the works of God, that a man shall not be able to discover the work which is wrought under the sun; whatsoever things a man shall endeavour to seek, however a man may labour to seek it, yet he shall not find it; yea, how much soever a wise man may speak of knowing it, he shall not be able to find it: for I applied all this to my heart, and my heart has seen all this.
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.
