'Searching' in the Bible

And I gave my heart to searching out in wisdom all things which are done under heaven: it is a hard thing which God has put on the sons of men to do.

And I set my mind to know [practical] wisdom and to discern [the character of] madness and folly [in which men seem to find satisfaction]; I realized that this too is a futile grasping and chasing after the wind.

a time to search, and a time to give up searching; a time to keep, and a time to discard;

I gave my mind to knowledge and to searching for wisdom and the reason of things, and to the discovery that sin is foolish, and that to be foolish is to be without one's senses.

See this which I have found, saith the Preacher, searching one by one to find out the reason;

For which my soul is still searching, but I have it not; one man among a thousand have I seen; but a woman among all these I have not seen.

This only have I seen, that God made men upright, but they have been searching out all sorts of inventions.

And because the Preacher was wise he still gave the people knowledge; searching out, testing, and putting in order a great number of wise sayings.
