Proverbs 23:9LXX

7For as he thinketh in his heart, so he: Eat and drink, saith he to thee; but his heart not with thee.

8The morsel 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.

10Remove not the old landmark; and enter not into the fields of the fatherless:

11For their redeemer mighty; he shall plead their cause with thee.
