Proverbs 27:21-23

²¹As is the fining pot for siluer and the fornace for golde, so is euery man according to his dignitie.

²²Though thou shouldest bray a foole in a morter among wheate brayed with a pestell, yet will not his foolishnes depart from him.

²³Be diligent to know ye state of thy flocke, and take heede to the heardes.
