Thematic Bible: What is hidden from mankind

"From where then cometh wisdom? And where is the place of understanding? She is hid from the eyes of all men; yea, and from the fouls of the air. Destruction and death say, 'We have heard tell of her with our ears.' read more.
But God seeth her way, and knoweth her place. For he holdeth the ends of the world and looketh upon all that is under the heaven.
