Proverbs 27:22-24

New International Version - UK

²² Though you grind a fool in a mortar,
    grinding them like grain with a pestle,
    you will not remove their folly from them.

²³ Be sure you know the condition of your flocks,
    give careful attention to your herds;
²⁴ for riches do not endure for ever,
    and a crown is not secure for all generations.
