Thematic Bible: How not to fast

And when ye fast, be not as the hypocrites, affecting a gloomy look: for they disfigure their visages, that they may make a shew of fasting to men. Verily I say unto you, That they have their reward. But when thou keepest a fast, anoint thine head, and wash thy face; that thou mayest not make a shew of fasting to men, but to thy Father who is in secret: and thy Father who seeth in secret shall reward thee openly.
