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 is mighty; He shall plead their cause with thee.
12Apply thine heart unto instruction, And thine ears to the words of knowledge.
Proverbs 23
