Proverbs 27:21-23

Expanded Bible

²¹ A ·hot furnace tests silver and gold [crucible for silver and a furnace for gold],
and people ·are tested by the praise they receive [^Lin the presence of those who praise them].

²² Even if you ground up a foolish person like grain in a bowl,
you couldn’t remove the foolishness.

²³ Be sure you know how your sheep are doing,
    and ·pay attention to the condition of [^Lset your heart on] your cattle.
