'Discover' in the Bible

would not God discover this, for he knows [the] secrets of [the] heart?

I also {explored} {the effects of indulging my flesh} with wine. My mind guiding me with wisdom, {I investigated} folly so that I might discover what [is] good under heaven for {humans} to do {during the days of their lives}.

{Whatever is--it is far beyond comprehension}. Who can discover it?

Then I saw all the work of God--man [is] not able to discover the work that is done under the sun. Although man may toil in seeking, he cannot find it. Even if a wise man claims [that he] knows it, he cannot find it.
