Sirach 22:16-18

New Revised Standard Version Catholic Edition

¹⁶ A wooden beam firmly bonded into a building
    is not loosened by an earthquake;
so the mind firmly resolved after due reflection
    will not be afraid in a crisis.
¹⁷ A mind settled on an intelligent thought
    is like stucco decoration that makes a wall smooth.
¹⁸ Fences^[a] set on a high place
    will not stand firm against the wind;
so a timid mind with a fool’s resolve
    will not stand firm against any fear.
