Proverbs 29:15, 17-18

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. Where there is no vision [no revelation of God and His word], the people are unrestrained; But happy and blessed is he who keeps the law [of God]. [1 Sam 3:1; Amos 8:11, 12]
