6. Eat thou not the bread of him that hath an evil eye, neither desire thou his dainties:
7. For as he reckoneth 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.
