Proverbs 23:10LXX

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.

12Apply thine heart unto instruction, and thine ears to the words of knowledge.
