Sirach 33:4-6

New Revised Standard Version Catholic Edition

⁴ Prepare what to say, and then you will be listened to;
    draw upon your training, and give your answer.
⁵ The heart of a fool is like a cart wheel,
    and his thoughts like a turning axle.
⁶ A mocking friend is like a stallion
    that neighs no matter who the rider is.
