Proverbs 23:11-13

Amplified Bible

¹¹ 
For their Redeemer is strong and mighty;
He will plead their case against you.
¹² 
Apply your heart to discipline
And your ears to words of knowledge.

¹³ 
Do not withhold discipline from the child;
If you ^[a]swat him with a reed-like rod [applied with godly wisdom], he will not die.
