Proverbs 23:7-11

For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

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

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

Remove not the old landmark; and enter not into the fields of the fatherless:

For their redeemer is mighty; he shall plead their cause with thee.
