Proverbs 23:7-9

Authorized (King James) Version

⁷ for as he thinketh in his heart, 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 ears of a fool:
for he will despise the wisdom of thy words.
