ECC 8:17

17 And I understood, that of all the works of God, a man may find no reason of those things, that be done under the sun, (or And I understood, that of all the works of God, a person can find no reason for those things, that be done under the sun); and inasmuch as he travaileth more to seek (it out), by so much (the more) he shall find (it) less; yea, though a wise man say that he knoweth, (or understandeth, what is done under the sun), he shall not be able to find (it out).
