Proverbs 23:7-9

New International Version - UK

⁷ for he is the kind of person
    who is always thinking about the cost.^[a]
‘Eat and drink,’ he says to you,
    but his heart is not with you.
⁸ You will vomit up the little you have eaten
    and will have wasted your compliments.

⁹ Do not speak to fools,
    for they will scorn your prudent words.
