9 Do not speak to a fool,
for he will scorn the wisdom of your words.
10 Do not move an ancient boundary stone
or encroach on the fields of the fatherless,
11 for their Defender is strong;
he will take up their case against you.
12 Apply your heart to instruction
and your ears to words of knowledge.
13 Do not withhold discipline from a child;
if you punish him with the rod, he will not die.
14 Punish him with the rod
and save his soul from death.
15 My son, if your heart is wise,
then my heart will be glad;
16 my inmost being will rejoice
when your lips speak what is right.
17 Do not let your heart envy sinners,
but always be zealous for the fear of the LORD .
18 There is surely a future hope for you,
and your hope will not be cut off.
19 Listen, my son, and be wise,
and keep your heart on the right path.
20 Do not join those who drink too much wine
or gorge themselves on meat,
21 for drunkards and gluttons become poor,
and drowsiness clothes them in rags.
