Sirach 22:14

¹²Seven days do men mourn for him that is dead; But for a fool and an ungodly man all the days of his life.

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.

— Sirach 22:14 —

¹⁵Sand, and salt, and a mass of iron, are easier to bear, Than a man without understanding.

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