Proverbs 27:21

As the fining-pot for silver and the furnace for gold, both of them serving to bring out the purity of the metals tried in them, so is a man to his praise, he is tested, his real character is disclosed, by his glorying or boasting, whether this is concerned with praiseworthy or with blameworthy and trivial things, or, according to the opinion in which he is held by honorable people. cf Proverbs 12:8.
