"And when you fast, do not look gloomy, like the hypocrites, for they disfigure their faces that they may be seen by men to be fasting. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, so that you do not appear to be fasting to men, but to your Father who is in secret; and your Father who sees in secret will reward you.
