16 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 fast. Verily, I say to you, they have their reward.

17 But thou, when thou fastest, anoint thy head, and wash thy face;

18 That thou mayest not appear to men to fast, but to thy Father, who is in secret: and thy Father, who seeth in secret, shall reward thee openly.
