9. Speak not in the ears of a fool: for he will despise the wisdom of your words.
10. Remove not the old landmark; and enter not into the fields of the fatherless:
11. For their redeemer is mighty; he shall plead their cause with you.
12. Apply your heart unto instruction, and your ears to the words of knowledge.
13. Withhold not correction from the child: for if you beat him with a rod, he shall not die.
