Proverbs 23:9-13

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.

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

Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
