Proverbs 27:19-21

¹⁹As the faces of them that look therein, shine in the water, so-the hearts of men are laid open to the wise.

²⁰Hell and destruction are never filled: so the eyes of men are never satisfied.

²¹As silver is tried in the fining-pot and gold in the furnace: so a man is tried by the mouth of him that praiseth. The heart of the wicked seeketh after evils, but the righteous heart seeketh after knowledge.
