Proverbs 27:22-24

New International Reader's Version

²² 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.

²³ Be sure you know how your flocks are doing.
    Pay careful attention to your herds.
²⁴ Riches don’t last forever.
    And a crown is not secure for all time to come.
