9Do not speak in the hearing of a fool, for he will despise the wisdom of your words.
10Do not move an ancient boundary stone or encroach on the fields of orphans,
11for their Redeemer is strong and he will plead their case against you.
12Apply your heart to instruction and your ears to words of knowledge.
13Do not withhold instruction from a child, for if you discipline him, he will not die.
