Proverbs 17:10-12

EasyEnglish Bible

¹⁰ You can warn a wise person once and he will learn what is right.
    But a fool never learns, even if you hit him a hundred times.
¹¹ An evil person never obeys authority,
    so a cruel messenger will come to punish him.
¹² Do not go near a fool who is doing stupid things.
    It would be safer to meet a mother bear who has lost her babies.
