And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this grievous labor hath God given to the sons of man to be exercised with it.

So I returned, and considered all the oppressions that are done under the sun: and behold the tears of such as were oppressed, and they had no comforter; and on the side of their oppressors there was power; but they had no comforter.

I applied 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 beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man may labor to seek it out, yet he shall not find it; yes further; though a wise man thinketh to know it, yet shall he not be able to find it.
