'Seeking' in the Bible

which I am still seeking but have not found. I have found one man among a thousand [who pleases God], but I have not found [such] a woman among all these [a thousand in my harem].

and I saw all the work of God, I concluded that man cannot discover the work that is done under the sun. Even though man may labor in seeking, he will not discover; and [more than that], though a wise man thinks and claims he knows, he will not be able to find it out.
