Proverbs 23:9-11

New Revised Standard Version, Anglicised

⁹ Do not speak in the hearing of a fool,
    who will only despise the wisdom of your words.
¹⁰ Do not remove an ancient landmark
    or encroach on the fields of orphans,
¹¹ for their redeemer is strong;
    he will plead their cause against you.
