Proverbs 23:7-9

Revised Standard Version

⁷ for he is like one who is inwardly reckoning.^[a]
    “Eat and drink!” he says to you;
    but his heart is not with you.
⁸ You will vomit up the morsels which you have eaten,
    and waste your pleasant words.
⁹ Do not speak in the hearing of a fool,
    for he will despise the wisdom of your words.
