Thematic Bible: How not to fast

Moreover, when ye fast, be not, as the hypocrites, of a sad countenance; for they disfigure their faces, that they may appear to men to be fasting. Truly do I say to you, They have received their reward. But do thou, when thou fastest, anoint thy head, and wash thy face; that thou appear not to men to be fasting, but to thy Father who is in secret; and thy Father, who seeth in secret, will reward thee.
