Sirach 22:15

¹³Talk 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.

¹⁴What is heavier than lead? and what is the name thereof, but a fool?

— Sirach 22:15 —

¹⁶As timber girt and bound together in a building cannot be loosed with shaking: so the heart that is stablished by advised counsel shall fear at no time.

¹⁷A heart settled upon a thought of understanding is as a fair plaistering on the wall of a gallery.
