9Do not speak to a fool, for he will despise the wisdom of your words.
10Do not move an ancient boundary stone or encroach on the fields of the fatherless,
11for their Redeemer is strong; He will take up their case against you.
12Apply your heart to instruction and your ears to words of knowledge.
13Do not withhold discipline from a child; although you strike him with a rod, he will not die.
