Nor detest His correction;

Just as a father the son in whom he delights.
Prov 4:10 Hear, my son, and receive my sayings,
And the years of your life will be many.
11 I have taught you in the way of wisdom;
I have led you in right paths.
Prov 12:26 The righteous should choose his friends carefully,
For the way of the wicked leads them astray.
Prov 13:24 He who spares his rod hates his son,
But he who loves him disciplines him promptly.
Prov 14:12 There is a way that seems right to a man,
But its end is the way of death.
Prov 15:10 Harsh discipline is for him who forsakes the way,
And he who hates correction will die.
Prov 17:10 Rebuke is more effective for a wise man
Than a hundred blows on a fool. 11 An evil man seeks only rebellion;
Therefore a cruel messenger will be sent against him.

Prov 23:13 Do not withhold correction from a child,
For if you beat him with a rod, he will not die.
14 You shall beat him with a rod,
And deliver his soul from hell.
