12 Apply your heart to instruction
and your ear to words of knowledge.
13 Do not withhold discipline from a child;
if you strike him with a rod, he will not die.
14 If you strike him with the rod,
you will save his soul from Sheol.
15 My son, if your heart is wise,
my heart too will be glad.
16 My inmost being  will exult
when your lips speak what is right.
17 Let not your heart envy sinners,
but continue in the fear of the Lord all the day.
18 Surely there is a future,
and your hope will not be cut off.
19 Hear, my son, and be wise,
and direct your heart in the way.
20 Be not among drunkards 
or among gluttonous eaters of meat,
21 for the drunkard and the glutton will come to poverty,
and slumber will clothe them with rags. (ESV)
Many are the plans in the mind of a man,
but it is the purpose of the Lord that will stand.
