Thematic Bible: How not to fast

And when ye fast, be not, like the hypocrites, of a gloomy countenance; for they disfigure their faces, that they may be observed by men to fast: I tell you, they have indeed their reward. But thou, when thou fastest, anoint thine head and wash thy face; that thou mayst not appear unto men to fast, but to thy Father who is in secret; and thy Father, who seeth in secret, will reward thee openly.
