Proverbs 23:7-9

American Standard Version

⁷ For ^[a]as he thinketh within himself, so is he:
Eat and drink, saith he to thee;
But his heart is not with thee.
⁸ The morsel which thou hast eaten shalt thou vomit up,
And lose thy sweet words.
⁹ Speak not in the hearing of a fool;
For he will despise the wisdom of thy words.
