Sirach 8:4-6

New Revised Standard Version, Anglicised

⁴ Do not make fun of one who is ill-bred,
    or your ancestors may be insulted.
⁵ Do not reproach one who is turning away from sin;
    remember that we all deserve punishment.
⁶ Do not disdain one who is old,
    for some of us are also growing old.
