The rod and reproof (godly instruction) give wisdom,
But a child who gets his own way brings shame to his mother.

Correct your son, and he will give you comfort;
Yes, he will delight your soul.

For though he understands, he will not respond [nor pay attention].

²¹ 
He who pampers his slave from childhood
Will find him to be a son in the end.
