Ecclesiasticus 22:14
13. Talk not much with a fool, and go not to him that hath no understanding: beware of him, lest thou have trouble, and thou shalt never be defiled with his fooleries: depart from him, and thou shalt find rest, and never be disquieted with madness.14. What is heavier than lead? and what is the name thereof, but a fool?15. Sand, and salt, and a mass of iron, is easier to bear, than a man without understanding.
