I think you would have to take that up with Solomon who wrote Proverbs. But there are only 2 choices the grave or hell. I am fairly certain that being punished does not keep anyone from the grave. So Solomon must have meant save him from hell by correcting the son so that he is not rebellious.
Proverbs 23:13-14
(13) Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
(14) Thou shalt beat him with the rod, and shalt deliver his soul from hell.[sheol]
How does being punished keep one out of hell? Scripture declares that all humanity is rebellious. So, explain how that applies to the atonement.
You know "beat" in Hebrew means to come after someone again and again and "the rod of correction" is the tool that's used. And "rod" in that sense is clearly metaphoric!
If your kid doesn't know how to do algebra; you don't physically hit them until they "get it right"? No, you find a method of instruction that works for them.
So why do we seem to believe that physically hitting kids is going to teach them how to behave?
I have a child who was extremely difficult to discipline. He never "learned the lesson" though until I could present it to him in a way that he could absorb it. And I made a lot of mistakes along the way.
The hardest lesson I learned was how to be the parent he needed; not the parent I thought I should be; or the parent other people thought I should be.
My son is almost 21 years old now. He still lives with me. He's got the developmental maturity of maybe an 11 year old; with the intellectual reasoning capacity of maybe a.... 40 year old? He's an "old soul" in a lot of ways. He can't remember squat though. (He's like someone with dementia though he knows he has it.) He gets confused and has difficulty processing information.
But he's 6 foot 1 inch and has like 70 pounds on me. I aint going to "beat" this kid into submission! (Besides he's got osteoporosis and if I injure him; I'm legally on the hook for assault!) Besides the fact that he'd be extremely emotionally distraught if I did something to intentionally injure him. He trusts me and that is something that took a long time to reestablish.
I came from an extremely dysfunctional background and though my parents weren't particularly physically abusive; (they did spank me when I was small) there was a lot of other types of abuse and neglect that went on. When I found out I was pregnant, I promised God and this child; that I was not going to throw him to the wolves of my dysfunctional upbringing. I learned a hell of a lot in those years about the development of the human brain.
My son respects me and obeys me; because I learned to develop a parenting style that was modeled off of my relationship with Christ. And I've known now for almost a decade that he's one of the elect. My son is a believer; despite he struggles with a lot in regards to the limitations his epilepsy causes.
I pray every day for wisdom from God; because I don't know how to help him. I can't do this alone. I know that. And God has brought me the resources (and people) I needed to help me help him get to the next phase of his growth process. And in a lot of ways; I believe my son has taught me more than I've actually taught him.
Now I was in the military for 3 years and did clean up after the 1991 Gulf War; But still, I think my son is one of the bravest people I've ever met. He's faced many life altering events on top of his own mortality; and he keeps going. He prays for help a lot despite the frustration and pain. I have a lot of respect for the kid and how he's prayed through his path in life!
But he would not have gotten as far as he has; if I'd ignored the lessons God was teaching me of how to teach him to be as independent and functional in society as he's capable of being.
After many tough years, multiple school placements and a lot of challenging behavior; there's peace, cooperation and a lot of love in this house. And that didn't happen with me hitting him.
