Wisdom of Ben Sira 22:14-16

New Catholic Bible

¹⁴ What is heavier than lead,
    and what is its name but “Fool”?
¹⁵ Sand, salt, and a lump of iron
    are easier to bear than a stupid man.
¹⁶ A wooden beam firmly bonded into a building
    is not dislodged by an earthquake.
So, too, a mind firmly resolved after due reflection
    will not be shaken in a moment of crisis.
