“When you fast, don’t be gloomy like the play-actors. They make their faces quite unrecognizable, so that everyone can see they’re fasting. I’m telling you the truth: they have received their reward in full. No: when you fast, tidy your hair and beard the way you normally do, and wash your face, so that others won’t notice you’re fasting—except your father, privately. Then your father, who sees in private, will repay you.
