Matthew 6:16
"In addition, when you fast [i.e., go without food and/or drink for religious reasons], do not be like the hypocrites with long faces, for they go around with gloomy expressions on their faces in order to advertise that they are fasting. It is true when I say to you, these people have [already] received their reward.
