If a godly person hit me, it would be an act of kindness. If they would correct me, it would be like pouring olive oil on my head. I wouldn’t say no to it. I will always pray against the things that sinful people do.
If you whip a person who makes fun of others, childish people will learn to be wise. If you warn those who already understand what is right, they will gain even more knowledge.
Suppose you could grind a foolish person in a mill. Suppose you could grind them as you would grind grain with a tool. Even then you could not remove their foolishness from them.
