Bible Verses About Fasting: Not to be made a subject of display

`And when ye may fast, be ye not as the hypocrites, of sour countenances, for they disfigure their faces, that they may appear to men fasting; verily I say to you, that they have their reward.

`But thou, fasting, anoint thy head, and wash thy face,

that thou mayest not appear to men fasting, but to thy Father who is in secret, and thy Father, who is seeing in secret, shall reward thee manifestly.
