Proverbs 23:6-9

⁶Eat thou not the bread of him that hath an evil eye, neither desire thou his dainties;

⁷For as one that hath reckoned within himself, so is he: 'Eat and drink', saith he to thee; but his heart is not with thee.

⁸The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.

⁹Speak not in the ears of a fool; for he will despise the wisdom of thy words.
