And I gave my heart to seek and search out by wisdom concerning all which is done under the heavens. It is a sad task God has given to the sons of men to be humbled by it.

I set my heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness;

Then I looked at all the work of God, that a man cannot find out the work that is done under the sun; because though a man labors to seek it out, yet he shall not find it. Yea, further, though a wise one speaks of knowing, yet he shall not be able to find it.
