Proverbs 23:7-10 American Standard Version (ASV)

7. For 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.

10. Remove not the ancient landmark; And enter not into the fields of the fatherless:
