Proverbs 23:11

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.

13Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
