Proverbs 23:8-10

New Revised Standard Version, Anglicised Catholic Edition

⁸ You will vomit up the little you have eaten,
    and you will waste your pleasant words.
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,
