Sirach 3:9-11

New Revised Standard Version Catholic Edition

⁹ For a father’s blessing strengthens the houses of the children,
    but a mother’s curse uproots their foundations.
¹⁰ Do not glorify yourself by dishonoring your father,
    for your father’s dishonor is no glory to you.
¹¹ The glory of one’s father is one’s own glory,
    and it is a disgrace for children not to respect their mother.
