to find: to come upon someone or something, whether after looking for it or by simply meeting it
At its core this word names the moment of coming upon something. Sometimes that moment ends a search, as when a shepherd hunts down a lost sheep or a merchant tracks down a fine pearl. Just as often it is unplanned, the chance meeting of a person on the road or a coin happened upon while sweeping. The one word covers both, because in either case the point is the same: what was not in hand a moment ago is now in hand.
From that physical core the word reaches in a few natural directions. It can mean to find out, to discover a fact by looking into a matter, which is why a judge can say he finds no fault in a man. It can be turned around into the passive, where to be found means to turn out to be a certain way once examined, so a person is found faithful or found with child or found in Christ. And it anchors a fixed expression, to find favor or find grace, which describes gaining someone's goodwill rather than locating an object.
These are not separate words but one act of finding pointed at different things: a lost object, a hidden fact, a person's standing, a place in another's favor. The thread running through all of them is arrival at what was being sought or simply was not there before.
